Sorry if I've asked in the wrong place, but does anyone know what readings on VCDS to show my MAF is working correctly ?
Trying to cure a cold start Miss-fire, that disappears after 1 minute of idling, but don't wanna splash out over £100 to get a new one if my diagnosis is wrong.

Trouble is , it missfire's like a bitch from cold, as soon as the revs drop from 1200 to 750 on warm up, approx 1 minute after cold start, the engine stops misfiring . No errors show in VCDS neither, my recent Emmisions tests have been poop recently and so has my MPG, so I'm wondering if this is the cause. Since having the Twintake installed, its been a problem. Might be coincidentle?
Any ideas?
-
Do it with the MAF disconnected.
-
I removed it 1st thing this morning, seem to clear, but didn't occur to me till late. Might of been where car had warmed after 1 minute, before I thought to do it. Gonna try in the morning and see if its cleared.
Just wanna be 110% sure before paying out. But with high emissions readings and higher then usual fuel consumption, might just bite the bullet.
Car is fine over wise .
-
oh dear not you as well having a cold start mis-fire. seems to be a lot of mis-fire issues of late.
have you confirmed it's a proper mis-fire though? blocks 15 and 16 will tell you if it's happening on all cylinders or just individual ones. then you can start narrowing down things and finding the problem

I will take a look, but as I said, its not showing in a full scan of errors ?

An autoscan wont generally show up misfires.

Ok.. To update, I logged 15-16 and indeed, shows I had a bad idle missfire on cylinder 4. Logging over 40 missfire's on each cycle of scan..
1st thing I then did was swop coil packs, then spark plugs from cylinder 1 to 4 to see if fault would hopefully move.But alas it didn't :sad1:
So consulted the knowledge of a forum legend ( hurdy) and after disconnecting the MAF, the rate in which the missfire's were happening was less.
So it pointed to Dirty Gummed up exhaust and inlet valves.So use the Can of Wynns via the MAF port , whilst holding revs at 2000 rpm, and spray contents in , in stages .The results were conclusive, the rate of missfire's got even further less down to under 20 per cycle. After putting engine back together , road test and a 2 mile quick sprint, missfire's are now at Zero and interestingly, my idle speed has increased to 780-800 and not hint of judder on engine note and also a very smooth idle.
So the moral of the story is, that I'm gonna go buy another can tomorrow :laugh:

I bought a similar product but never tried it.
Glad that solved your problems Steve :happy2:

Good to hear you've made some progress. Did you inject the fluid by removing the IAT sensor?
I still don't think this stuff can shift much off the coked up valves but it might have dislodged some lumps hanging on?

Glad you got it sorted Steve :happy2: How do you log 15-16 ? If you dont mind me asking, I seem to be getting more of a splutter in the morning, 2 mins down the road when i have to add abit more pedal for a busier road, it only seems to have come on more recently...
I am wondering is it something the same, i stuck a new maf in tonite so, i will tell if it has helped in morning, as it only happens when cold an left overnight...
I am not one for having to be hard as the car has not fully warmed up yet, but at times i have no choice but speed up abit,, just for a short distance and not for too long.. It does thow up some what looks like exhaust fumes or steam, which cover the back window... :confused:
again no faults coming up on vcds... it has me baffled.
the only thing that has changed is a new clutch fitted, now with over 1000 miles on it, so should be worn in abit ...
and an oil change at the same time...
Don't mean to highjack your thread, just incase its along the same line mate :happy2:
thanks :wink:

How do you log 15-16 ?
Open vcds>select>engine>measuring blocks>enter 015 in the first box>go. Do the same in the next box for 016.
Click log>do a run or just look at the numbers by pressing start. Click stop when finished. :smiley:

Yes, , just start her up, someone on the loud pedal at 2000rpm and squirt every 15-20 secs depending on revs.
Been out in it tonight, certainly a lot happier on idle speed, but truth be told what she'll do in the morning is what it's all about.
Update to follow in the morning.
-
This mornings cold start.. Same again :sad1:
Missfire again detected on cylinder 4.
Must be gummed up valve/injector?.. Not sure what to do next, buy some more Cans of Wynns? :sick:
-
Don't keep cleaning them. Get it to a specialist.have you tired swapping cylinder 4 plug and coil pack around as a pair?

It must need a decoke..as the Wynns improved the running whilst warm ,but obviously not enough to clean the problem.i only used half a can not the complete can so might not had been enough?

You need a borescope to have a butchers.

Give JKM a call. Perhaps once sorted a catch can would be beneficial? Would help in the long run. How many miles? what fuel used?

A catch can has proven useless by other members, so I won't waste my money on fitting one, car has done 67k, and always run on Tesco 99.
Been doing long runs recently and it's still the same. ( up to Solihull etc this past weekend)
Need I think to find someone that will do a compression check, and do a decoke, without going to the expense of a head overhaul.
Car only shows idle speed missfire at idle, no issues up the rev range, and Cold starting if the cars left to idle for 20 seconds , the fault then also appears.The Wynns has made a difference so to me it must be a case of working out best way next without huge expense as its something I could really do without right now. :sad1:
Need to find someone in Hampshire that offers something like terraclean ?

Walnuts anyone?

By the time you've tried all sorts of remedies that are ineffectual it would have been cheaper to get the head popped and cleaned.
At least pay someone to take the intake manifold off so you can see if it is the valves that are coked up.

Steve I have a can of something in the shed thats designed to clear gunk off valves, i'll let you know what it is. Could always bring to JKM (if your coming?)

mass air / .8g/s = whp
mass air / .68g/s = crank hp
Group 002 will. Intake air mass should read a minimum of 0.8(g/s) * WHP if whp is known (I believe it is 0.68 for bhp). If low or even close to the minimum it needs replacing now or soon.
Another way to quickly check the maf sensor is swap yours using a bud's not having the issue.
Have you replaced the #4 plug yet?
I clean my valves every 10k miles and have had no misfires through 93k miles.
Cleaning the valves my way:
-
Did u get a look at what the plug was like on 4 compared to the others?
Darker or lighter?
Think it's time the intake manifold came off for injector swap.

Darker on cyl 4 lee. Yes does look like a faulty injector.Somethings up as the car doesnt appear to be making full power accoarding to the MAF readings i took today at full chat of around 220.8 :confused:
Whether a duff injector would cause power loss and show that air speed/mass would also suffer if one cylinder is not 100%?
-
That suggests spark plug / coil pack. Dark normally equates to running rich. My plug was clearly lighter than the other 3 hence it pointed to faulty injector and running lean!
But get it looked at by a pro is best way cos im a numpty lol
Ps. I changed all 4 plugs too at same time mind.

What ever it is, i hope you get it sorted soon matey :happy2:

Thinking about it, one plug was darker then the other, I just pulled plugs 1 and 4 out , can't remember which one was which, but a deffo imbalance.
Does anyone know, would the MAF reading be suffering if an injector isn't working properly? Or is that a different issue.
To be on stage 2 bluefin with a forge Twintake, seems abit low to me.?

220.8g/s on the MAF equates to around 276 bhp. So you're missing 25+ ponies!

No. The maf reading would not be affected. It only reports/suggests how well the maf sensor is reading. But since it reports/suggests, it leaves the ecu to make requests due to data reported by the maf. So with a failing maf - the ecu will cut back and these cuts will show in your requested fuel pressure and more.
My data below with a good maf sensor shows I'm good for 295whp, and I dyno @ 290whp.

Apologize for the earlier equation. We do whp here.
220.8 / 0.68 = 324hp
220.8 / 0.80 = 276whp
I don't know the ratio of hp to bhp if any...sorry ;p
Your maf seems close perhaps for your stage remap, yes?
Time to sort out whether the dark or light plug came from the #4 cylinder now.
If dark: you have misfire in #4 and it is a plug, coil, or poor valve seal in #4
If light: injector
-
Going to take the plugs out this morning, I have a spare set of NGK iridiums, so will put these in from cold, and see if the car starts misfiring from cold again.
-
Fingers crossed here ;p
-
Well found out the answer as to why my thoughts of 220.8 on the MAF were low, and that was because of an "amendment" to my remap back in may 2011, when I asked Superchips to "tweak" my remap, what they had actually done was put my car back to Stage 1 without telling me.. :fighting:
So means my car on current config with my Twintake installed exactly 1 year ago, means that my car has never had stage 2 !, in other words I've been running stage 1 for a very long time! :signLOL:
It now has stage 2 and now goes even better especially higher up the revs now. :driver:
Still have an injector on number 4 cyl that's misfiring a handful of times on tickover though,but not a biggy.
I also at the same time changed my spark plugs to a spare set of NGK iridiums I had to rule out a dodgy plug.
Gonna keep an eye out for a spare injector in the mean time.

I questioned them and asked what file do I have on my device and was abit shocked.
I then had to proove that I did indeed pay for an upgrade as he didn't believe me that I had when I told him I should have it.
Fortunately I found a bank statement in case they Said I never payed, but fortunately they agreed'd to resend the stage 2 file.
The mistake was made when I asked them to amend my map with an issue in MAY 2011 ,which I've since replaced various items to cure the problem, so I thought I was running a stage 2 turned down map, but instead they had just given me back a stage 1 file unbeknown to me :fighting:
I can confirm after logging, I'm suffering with no misfires when underway with my current misfire issue, so nothing's gonna go bang for the time being. I can live with the odd misfire at idle as it has improved since put these cans of Wynns through the engine, and I'm sure this odd misfire is down to Carbon build up.
I've heard JKM recommend something to clean injectors out with (SNP) ?? Which might be worth filling the fuel tank with to see if that helps.Apparently it's not uncommon for these engines to have the odd misfire, so I will just keep an eye on it for the time being, as with me still being off work with my back injury, I can do without the expense right now.
If the cold start running issue gets worse then need to get it sorted ASAP.

I can confirm stage 2 now on the car is very good rich.. MAF now says 305bhp.. Not worth spending £500 on another type of software for the same end result :happy2:
As Superchips always say " it's not the software, it's a fault elsewhere". Well I can safely say they got that right :laugh:

Little Update.
After giving it some thought as to what to do next to cure my Lazy Number 4 injector, I've decided to book the car in have a Terraclean done to her.
The misfire I have is only really apparent on Cold starts for the 1st minute and also after long periods of idling.
After seeing this on Discovery with Ed China giving it the thumbs up, and looking at cost over replacing injector and cost of few hours labour at jkm(my nearest TFSI specialist) it's worth giving this a whirl.
Turns out I have a local dealer of this on my doorstep in Hamble (1.5 miles from me)
Incase anyone hasn't seen about Terraclean..

Car is being done Tomorrow now at home around 1pm, so watch this space for results which being one of the 1st may be quite interesting.

I cant access the link (as i'm at work :wink:)
Does this clean the inlet side of the engine as well or is it just a fuel system clean (like a posh redex / Forte)?

Does it a lot better by the looks of it :happy2:
Does the lot from fuel rail to exhaust cat..
I'd advise a watch of the video when you get home gray... Looks like a great answer to our cars Achilles heal.

If it's injected with the fuel then it can't clean the inlet side of the engine.

Thanks,
Yeah I will have to watch the video. Read some reviews and folk seem to rate it. :smiley:
Just out of interest have you tried a throttle body adaptation to cure your misfires?

Yes, and its not that or I'd have multiple cyl misfires which I don't :happy2:

If it cures my injector issue which means if its a fuel substitute ,then happy days. It promises low HC and better engine performance and economy , then £90 well spent :happy2:

So how does he do it on the TFSI Steve?

Didn't ask but he says its not a problem. Will find out tomorrow I guess... :happy2:

Recon he disconnects the fuel line and insets their own line hooked up to the fancy machine :popcornsoda:

How's that going to clean your inlet valves?

How's that going to clean your inlet valves?
It isn't :stupid:
May clean your fuel lines, cylinder, exhaust valve and exhaust system though. They run the engine on their own fuel which has some magic cleaning power.
I wondered whether they could disconnect the MAF and run it on some form of inlet cleaner. Maybe that's the next revolution in direct injection cleaning. . .
Steve - may be worth a run on the rollers with your new map and clean fuel system?
-

I'm not fussed about the valves Ian, my injector is my objective as I agree, if this goes on the fuel rail, then this will treat everything from the rail to the exhaust Cat.
If I didn't have this misfire then I wouldn't be trying this. But I now my valves aren't the issue as when warm, the car is fine .
We shall see. If I get better mpg after, and a better performing car,then it's money we'll spent. You can't have clean valves all the time. :grin:
-
If the injector is f00ked no cleaning will fix it!
It'll help ur high HC readings though potentially but yeah I can't see how it will clean the inlet valves as it DI bypasses that!
They claim on their site it works for DI though so lets see how Steve gets on

The injector seems to be working ok 90% of the time :grin:
I'm looking foward to the results :happy2:
-
Yeah I thought that till all the lights came on
Just watch out for the EML mine didn't come on for a few weeks.
But I think it's inevitable unfortunately

Either that or AKS changed an injector that might of been salvageable ?
No one knows that this Terraclean will or won't do, so it's a cheaper alternative to an expensive decoke , then it's worth a go.
Even a fuel mpg improvement will be worth it :grin:

Well the swap fixed the problem straight away. There wasn't much build up the mani was off from what he can see.
Mine was probably a load more than u though. Was counting into the hundreds and thoughout the rev range

Well had the car done.. Early days yet, but I can confirm it starts faster from warm, feels smoother on power delivery at any given point on the throttle. Won't know just yet on mpg as its too early to tell.
Looking at the misfire count, after 5 minutes of idling, it managed just 6 misfires in total over that period, compared to when I first found out, I had nearly 50 misfires within 1 minute.
After going for a blast , the crap in the exhaust has stained my gravel driveway :laugh:..
Overall , seems worth a go but unsure with regard to the inlet track as the two canisters are designed for Red (fuel system) and black (combustion).i sort of got the impression I knew more about the TFSi engine then the Actual guy from Terraclean :scared:

If I was you, I would also try the "italian tuneup" which is also what VW recommends. Drive 20-30 minutes with rpm atleast over 3500, so use low gear on highway. This should bring up the inlet valve temperatures to burn away some sh*t. I tend to do this once or twice a year and I have zero misfires. Dont know how my valves look like but engine works ok. I just passed 100kkm, so its not that old but just throwing out an extra idea.

Tried this half dozen times, and it didn't do a thing (apart from drinking stacks of fuel lol) and why had to try something else.
Certainly saved me from cost of new injector and inlet manifold removal costs.

I wouldn't bank on it.
I had the same issue when I was on stock injectors but mine was cylinder 3. It was fine when warm but misfired when cold. After the K04 conversion with new injectors the misfire completly disappeared.

I read on briskoda that you just changed your injectors and didn't bother cleaning your inlet valves out and your car is fine now??
so if that's the case, if Terraclean didn't clean where it should then, I've got nothing to worry about? :confused:
At least I know that the fuel system and combustion/exhaust system with sports cat would of flushed out, well looking at my tail pipes, its extremely black now :grin:
-
The terraclean is suppose to clean injectors?
-

Yes the red can treats the fuel system from the fuel rail, and the black can does the Combustion/exhaust side.
The cars fuel and return are blocked off and the contents of the cars are pressurised to I think 40psi I think.
I asked the question to the operative about this not reaching the intake valves, and his answer was at that pressure it will because its under pressure and the molecular reaction will do enough...
I think different as I read that Terraclean offer an intake Carboniser which my Rep didn't see need for it.. Jury's well out on that but I wasn't gonna stand and call him a pleb... :mad:
We shall see how it goes.. :happy2:
-
40psi = 2.8 bar
Your fuel line runs at approx 115bar. :happy2:

Correct, I tried but gave up on cleaning the valves, it was stuck like tar!!
My car runs spot on now, after I replaced the faulty secondhand K04 injector grrr.
If you use a good quality fuel such as vpower they contain a good quantity of detergent so you should never need fuel line cleaning additive.

This mornings Cold morning start up.
I can confirm, misfire has now gone and car idles like a dream. Problem resolved :drinking:
Draw your own conclusion, but I'm satisfied that the Terraclean treatment has made a big difference to sorting out my cold start and misfire issue. :happy2:
-
What fuel do you use Steve?
Happy Birthday btw! :-)
-
After 10k or so my inlets are getting gungy again even after I removed my valves and fully cleaned the ports:

I cant find th pics I took after 10k of the ports again. I run a catch can so imo these make bugger all difference to keeping the ports clean.

any update in the last couple of days?
Im considering having the terraclean treatment in the next few weeks.
Been quoted £100 in Hammersmith, near me in London.

i got mine done at r-tech for a test. it was 100% smother and my engine had only done 11k.

Mine is certainly happier since.Much more eager to go and alot smoother :happy2:
-
My GTI is currently at 48k (bought it at 29) and AFAIK it's never had any such treatment. Idles so smooth I can't even feel it!
-
I would only recommend Terraclean if your exhaust emissions results are either a failure or near the limit.
You would still need to put something through the intake as the Terraclean using the red and black cans doesn't go via the inlet track.(red for fuel system and Black for combustion ,exhaust system and Cat.
Using the combination of the Winns EGT cleaner and Terraclean has sorted my running issues.
As yet Terraclean aernt using the kit I posted that cleans a Direct injection engine such as the TFSI. :sad1:
-
Just to update , issue of rough running from cold has returned, so she's off to JKM for diagnosis tomorrow :sad1:

Sorry to hear about your cold start issues, It's a strange one to go away after one minute of idling I Hope JKM can put some closure on the subject for you Steve!

So instead of "investing" your money in Terraclean you had replaced the faulty injector we wouldn't be having this discussion would we?

There is that, but I have no doubt my exhaust system was cleaned out along with other items..
My mpg has still had an improvement , and car runs alot smoother then it did prior, even with an injector issue sub 1800rpm.
I still wouldn't discount it Ian totally ,after all an injector fault if carbon isn't the cause, then for the sake of £85, over a bill of over £400 I now have from JKM to stump up, it was worth trying first rather then taking a chance it maybe faulty.
I'm still not discounting Inlet valves gummed up , as yet the manifold hasn't been removed so jim said that he also agree's on my diagnosis after he spent over an hour yesterday checking her over.
Will be back together latest Tuesday if I get chance to collect the car.
If it is Valve trouble, then rest assured as I've said with Terraclean, they will be hearing from me for falsely selling me their product.
-
So how are you going to speak to Terraclean if your valves are gummed up?
They already recommend a different product for direct injection cars which they didn't use to treat yours. :confused:

You don't normally have guarantees and come back on work they haven't done.

But when I asked before he started, he said " you really don't need it" as it still clean them due to the "molecular physics " :confused: :stupid:
Terraclean won't like bad publicity trust me :signLOL:
-
I've got to admit I've been waiting for your problems to return, I'm surprised it took so long. :confused:

Update*** :pomppomp:
Got the call from JKM today, car is all fixed. Fault confirmed as a fooked number 4 Fuel Injector.
Car now idle's really smoothly now, so much so you have a hard job to feel it running whilst stationary on the road :happy2:.
-
Good work. Sorry I missed your call earlier though ( dinner must've been on the table! :party: )
