Title: If it's not the DV or the coil packs what is it? - Update and confused!
Post by: brookesb32 on September 28, 2011, 09:20:23 pm
Hi all,

First post and hopefully your brains can help me because mine is very confused!  :confused:

A week or so ago, whilst on the country lanes at 50mph in 5th, i put my foot down and the car felt like it was stuttering or losing boost. First of all i thought i must have imagined it, however it continued doing it for the rest of the journey, and not just in 5th, it happened at low-mid revs in 3rd and 4th too, but mainly 4th and 5th.

A little hard to explain but it felt like someone pushing you in the back whilst running - or something slipping and then moving again. A light juddering you could say.

Anyway, after some research i thought it could be the DV so bought the new D Pistion type version and fitted that, and for a day it felt a bit better. Then nope it started again. It normally happens under hard acceleration and most noticable in 3rd through 5th. If i properly stick my foot down it really feels juddery in power, but still seems to pull well. It happens to a less extent under normal acceleration.

The car had a major service in May  at the local VW dealer and they completed the 28F5 coil pack recall change then too, so i would think the coil packs are ok.

No codes or faults come up when plugged into vcds, although it is not a proper Vagcom, and no lights on the dash.


I'm really struggling to work out what the problem is - but will not be ripped off by the £90 an hour diagnostics charge the local VW dealer wants.

Car is a 55 plate (nov reg but i think pre the change as has the older style of wiper blade connectors)



Help!!!!! Any thoughts? could it be the PCV?

have the spark plugs been replaced? Could possibly be a fuel pressure related fault, high or low side, might be worth poping your oil cap off and giving it a sniff, make sure it doesnt smell of fuel indicating possible fuel pump cam follower wear.

Post by: brookesb32 on September 28, 2011, 09:28:54 pm
i believe so yes, replacing the plugs was part of the major service. Had the oil cap off, and seems to smell ok, but had a little tinge to it - couldnt say if it was different than should be. Would it have a heavy fuel smell?

I did wonder if it was something to do with the air/fuel mixture?

thanks for the quick reply btw

Post by: heady2010 on September 28, 2011, 09:50:00 pm
ye it would stink in the cam cover if the follower was worn enough to cause a fuel pressure drop. i think it needs to go on proper scanner, have a look round at garages, really you shouldnt be charged full diag if they cant tell you what the fault is, also if it is an involved fault and they carry out the work for you, if its not fixed then you dont pay. Does the fault occur all the time? Is the car remapped?

Car is completely standard, and agree looking like need to do a proper scan, may have to have a word with my local independent place.

Fault didnt occur today (did yesterday) but then it only went 5 miles to the station and back. Idle settles find and not rough either, in case that came up.

Had the engine cover off to look at the coil packs, and couldnt see any part numbers on them to check if they are new versions - but nothing on view - are the part numbers underneath/on the tube part of the pack?

My money is on the N75 wastegate boost solenoid... something my cars in the garage today being fixed... sounds very similar symtoms as to what i had...

Log(or get someone to log) the N75 duty cycle... mine was proper erratic coming on, then suddenly shutting down, coming on higher values to compensate then shutting off... givin gthe stuttering effect i could feel through the pull of the car...

I had the coilpacks changed on mine under the recall recently and compared to the old packs it is noticably juddery in low revs especially when cold. It seems OK above 2500 rpm though. It was something I noticed straight away and thought maybe it would settle after a couple of days but it's still there. It's worse when cold and only slightly noticable when warmed up.

Had a compression test but as PDT Dave said it needs to be more in depth testing to really make issues apparent  :sad1:

Do get a fluttery boost sound.  Am replacing the n75 valve as matter of course, when I take dipstick out the engine doesnt run like sh*t as expected, in fact there is no change in engine note or hunting....  :sad1:

no real fluttery boost sound on mine, more of a 'skip' motion when accelerating, did it on the way home today and definitely worst when in 4th or 5th gear, but flutter/judder/skip would sum it up

I had exact same problem recently, only happened about 2-3 times, randomly. Like you, seems to occur in higher gears, 3-4 or 4-5.

Changed spark plugs and seems ok at the moment. Spark plugs were very loose when I changed them.  :confused:

Also got cam follower change on the 'to do' list.

Hmmm interesting. Mine has been like this for nearly 2 weeks now and is wrecking the usual smooth ride. Certainly hope it isnt the spark plugs as they replaced those during service a mear 5 months back.

Short of changing  the N75 and the PCV plus hooking it up to a VAGcom im running out of ideas

Nope mine is completely standard as far as i am aware. VW changed mine (well they should do as part of main service - havent looked of course), in May and did the coil packs on the recall at the same time. Didnt have any problems the entire previous year since i bought.

Seat mech swapped plugs and on autobahn it still logged the fault.

Tried new coilpack, still logged logged fault on cyl3.

Fittin REV N PCV as matter of course this week.  My money is on injector & / or dirty valves not seating.  :sick:

I'm not having any faults logged... it just pulses in the higher revs.

Do our cars have vvt? Could it be a sensor for that? But surely that would log something?

hi all,

been doing some more research and came across this thread.

It refers to similar items that we have been experiencing and looks at the PCV

After taking my engine cover off and looking at my PCV it has the same issue as in this thread, so a call into the VW stealer on Monday to find out how much the parts are.

Post by: E30Dom on October 01, 2011, 06:15:05 pm
Surely if it was a sensor it would give me fault codes?

Would a loose spark plug or a boost leak give me this pulsing effect at higher revs?

After re reading John_o's thread about the duff APR map from Awesome I thought my ongoing disatisfaction with the mapping has more reasoning but.....

Yes it misfires on stock settings too....

Although I dont know if 'Stock' is genuinely OEM stock settings or APRs 'stock settings'...?

Have you done a compression test mike?

This does sound like your looking at a mechanical failure rather then a electrical issue, when you remove your dipstick with no difference in engine idle is most concerning , and the pcv is one thing to do before getting out the compression tester IMO.

However, PDT Dave was asking Robdf2 about the extent of testing and it seems for a propper result the compression testing needs to be more in depth.

I dont know to what extent the above test was done, only know it only took them 30 - 40 mins...

Pulling my dipstick out makes next to no difference  :confused: :scared:

The Seat tech said thids morning it was nothing to worry about???  :confused:  He said on the Audi 5cyl Engine hunting would happen but not neceserilly on my engine?

Mike,

I'm sure my garage is gonna do some more logging... but a question for you...

When you open the drivers door and you hear the fuel pump prime. which I believe is a low pressure pump from the tank, how does it sound, smooth or lumpy? Mind sounds a bit wheezy...
Title: Re: If it's not the DV or the coil packs what is it?
Post by: E30Dom on October 02, 2011, 10:25:50 am
Cam lobe wear
Background:
Excessive wear of intake camshaft lobe that drives the high pressure fuel pump. The wear limits maximum pump piston lift, causing fuel rail pressure fluctuations. The intake cam drives the fuel pump:

Symptom:
-Fuel cut-out when driving, esp. under WOT.
-Fuel cut-out symptoms range from soft pulsations of power to long-pulse bucking while in high-gear high-load situations (high gear at WOT, or up a grade). MIL may flash if cut-out is severe. Car will also go into hard-limp (no boost, 4500RPM limit) if severe enough.
-MIL ON
-P0087 Fuel Rail / System Pressure - Too Low
-P1093 Fuel Trim 2, Bank 1 Malfunction
-P2293 Fuel Pressure Regulator 2 Performance

Solution:
Increase surface hardening of camshaft lobe for the high pressure fuel pump. Improved intake camshafts have Part No. 06F109101B. Refer to TSB# 15 07 04

Not sure how the DV works but should it be open or shut under boost?

And does this look right? The last bit of travel looks/feels a bit stiff...?

MIke,

If you look at similar issues on the older s3/tt's when they mention missing on cylinder 3 they say it's the amplifier module, not the coilpack, but assume that's all built in on our coilpacks?

Found similar on mk4 site when I searched, and the symptoms were the same as ours; stuttering, hesitation under load and Shaking on idle.

Also took out the dipstick tonight and definitely made the engine rough the more pulled out. Exhaust tone sounded a little up then down in points, but may have always sounded like that at idle and I'm just imagining things  :smiley:

Mate,

Just picked my car up from APD performance.

She is back to full health, the culprit... SPARK PLUGS!

So guessing VW didn't replace them on the 40k, back in May!

Hope you have a similar outcome, but would suggest swapping them over...

I have this and its driving me mad. I had spark plugs changed, dv valve changed and VW say they changed the coil packs on the recal but I dont really trust them. I took it in last week and they could see nothing wrong, its stuttering all over the place , when car has low fuel its unreal the stuttering. Half a tank or more its not nearly so bad .  Its booked into JKM now as I trust those guys to advise me what is up .


How VW cannot see it is beyond me, I even had the light come on twice on dash as it was missfiring . The one that says go to vw as it could damage your cat. Their machine couldnt pick this up , totals knobs IMO

soooo, a bit of a follow - up to the saga.

Car been in the garage for new discs and pads at the rear (and now new calipers due to them ceasing - not cheap are they1  :laugh:) but also for a full diagnostic test....

..... which did not pick up one single fault, they did a full sweep and even took it out on the road with the scan and nothing.

So wondering if it is the spark plugs - they weren't convinced as normally it wouldn't be an intermittant fault, when they are gone they are gone kinda thing.

So people - thoughts on that one?  :confused:

I went to JKM this weekend as my car is spluttering etc, as said before my DV valve, coil packs and spark plugs have all been changed in last 2 months.

They put the map back on and the the car was running at 1 bar, when it should be 1.4 bar ( maybe someone could explain all this bar stuff to me as never had a turbo before ? ) . The down pipe was spitting out oil so they changed this. ( The vw garage changed the air con condenser 2 weeks back so how they didnt see this is beyond me). Anyway part fitted and back to  1.4 bar. Still stuttering though. JPM advised me they had same problem with ED30 and it was spark plugs, I only just had spark plugs fitted 2 month back though. So we binned the Bosche plugs which are naff apparently and changed for NGK Iridium which are also a lot cheaper funny enough.  Stuttering has gone and now its fecking quick  :signLOL:


So my suggestion is to bin those nasty bosch plugs and fit some NGK's  :happy2:

I hope it is the plugs, anyone know the best/cheapest place to why them? Eurocarparts has the ngk ones that are apparently the latest ones. £11.40 each but does have 25% discount on at the mo.

Gonna ring VW and ask what they would have out in when had service in may, then may check :)

 Just spoke with the VW garage that did my service and changed the plugs in May. They used part number 1KO 06H 905 601 A, but that could well be bosch or NGK by what the chap was saying - only one way to tell i guess :)

I had mine changed a few weeks ago by VW but they were still Cr*p. Take the bosch ones out and put the NGK ones in, 36 quid for 4.  :happy2:

Bosch are crap mate , NGK are miles better (according to JKM )

I think from a remap point of view, NGK are stronger plugs. Bosch are ok for normal use IMO

Hopefully a new set of NGKs will get rid of the little misfire I appear to sometimes get on idle.

So the concensus would be that to hopefully sole the hesitation /stuttering under acceleration would be to change my spark plugs, which annoyingly were only changed by VW back in may grrr?  :rolleye:

Yes , mine were changed by VW to new plugs 2 months back , bin them and get NGK. Maybe there was a fault with all the bosch ones produced this year  :signLOL:

Post by: brookesb32 on November 05, 2011, 12:15:39 pm
sooo i am now even more confused than before. Bought the new NGK spark plugs and set about changing them this morning, until i got the first of the old plugs out and found....


..... that it was also an NGK spark plug - with the new part number so exactly the same as the ones i just bought  :confused: (also the coil packs are the new ones too)

So i took a pic or two to show you guys, but imagine that this amount of blackness is completely normal? didnt see any water or moisture either.

Not sure where that leaves me now - still wonder if it could be the PCV??

Help it is driving me crazy trying to work this out  :stupid:

and then just to make my day i found this rust on my arch - although i hear this should be covered under the paintwork warranty?

Another update  :smiley:

After visting vwrascal (Dan) from the forum to buy the middle bit of the front splitter that mine was missing, was discussing my hesitiation problem and he said he had similar and he could do a VCDS scan for me (legend!) so after a tense moment it came back with says that there was a problem with the inlet manifold runner. Apparently it can get stuck and cause hesitation. I just hope that the hesitation doesnt come back (seemed a lot better on the trip back, although thought i felt a little still but much better) as the intake flap motor unit it rather expensive so i am told  :scared:

Think it is the round part at the front of the engine but might be wrong.
This is the code that came up too - -012599 - Intake Manifold Runner Control: Basic Setting not Completed

(https://www.mk5golfgti.co.uk/forum/proxy.php?request=http%3A%2F%2Fi1193.photobucket.com%2Falbums%2Faa358%2FBrookesb32%2Ftumble.jpg&hash=3eddf8461aecdbbc4f95d2d1d3e62e8ea7508005)


Dan was kind enough to do the reset recommended by the VCDS for me, and hopefulyl that will solve the problem

It won't......

Have you done the basic settings as it says?

My intake runner has a mind of its own, for weeks won't show a fault, then it will flag up an "implausible " signal once, and vanish again for another week or so.

Yes, the VCDS came up with two possible fixes, one was doing the basic setting reset and the other was replacing it, so we went with the first one  :signLOL:

Rescanned it and no faults at all came up.

I would recheck it in a couple of weeks to see if it's returned, but if it does, it's no biggy.

well that is good to hear - the hesitation/stuttering is rather annoying though, so hope it stays away! Dan said he had the same problem on his too, doing the basic setting made his fine for 6 months then he had to do it again, but had nothing since for over a year, so here is hoping that it doesnt!  :drinking:

and you would be correct Steve, starting hesitating again tonight  :sad1:

got a feeling the only way to fully fix will be the part replacement

Well thankfully apart from a few days after I had the VCDS reset on the flap, when it appeared to hesitate a little I have had nothing since so fingers crossed it will stay that way!
