Title: Misfire and Flashing EML
Post by: johnhol78 on August 11, 2011, 10:39:10 pm
For the last few months I've had what I thought was fuel cut.....though always when I wasn't logging  :ashamed:

Power loss when changing from 3-4 and 4-5

Though tonight when i accelerated it jerked a few times and the EML started flashing....eased off and then it went off.

Got home and scan for errors and got -

Went and did some runs and got nothing - all normal again.

Had coilpacks changed in the "recall" only a few months ago. Should I be taking this back to VW and letting them sort it, surely this is within a timeframe that they should cough up if it's the coilpacks???

Any ideas?

Same symtoms here on revised coilpacks but German dealer won't
Change them even though covered by 2yr European warranty (bought at Uk dealer)

Take it back and try new coilpacks.  How old are your plugs?

Knackered plug maybe? Take the engine cover off and check the connections are all secure mate. To be honest though yours is doing exactly as mine was when the coil pack failed.

Go out and log block 015 (Misfire counter) to see what coils are affected.

Will do this on the way to work.....thanks mate.

Also the plugs are about 3-4 months old.

Bought from Edition 30 Phil on here. Must admit I had the 4 prong plugs before though these are single prong. Not sure that would effect them.

What make and type of plug are you presently using?
Title: Re: Misfire and Flashing EML
Post by: Tfsi_Mike on August 12, 2011, 08:48:58 am
I tried 1 step colder irridium and gave me a missfire ended up needing new coilpack, again :(

Be interested to hear what other plugs people are using.

Currently have a miss fire, plugs only been in 2000miles. Replacing all 4 coils next week, considering doing plugs again at the same time incase faulty coils damaging the Plug.  Don't want to go round in circles with the fault

Well logged this morning and nothing though tonight it's definitely cylinder 2......

Not sure about spark plugs....though will be taking plug out this weekend on c2 so will tell you then.

I had the same happen to my car about 4 weeks ago.  Took it to the dealers and they said they could see the misfire but the fault guidance did not find an issue with any component. 

So nothing has been done under warranty  :sad1:...

In my opinion if it's happened once it will happen again, just a matter of time.  I had my spark plugs changed back in Sept 2010.  Since then I've done around 15K miles without issue... so my initial feeling is that its a coilpack on its way out.

Incidentally, the spark plugs fitted were Denso Iridium Power IK24 and the faults logged were:

I've got exactly the same problem, reporting exactly the same in VCDS, multiple cylinder misfire and C2 misfire, have swapped coilpack and spark plugs which has made no difference, have the day off tomorrow so going to try to log some data to narrow it down.

Spent a bit of time looking at VCDS and popped up to a local mechnic I know and both point to injector, so looking to replace the injector in C2 to solve it. I'm away until next week now so won't get a chance to sort it for a week. Will let you guys know how I get on.

Finally got around to some investigation work.

Light came on solid last night and read the code and still said misfire on cylinder 2

Swapped the coilpacks on 2 and 3 and went out.

Drives better now  :confused: and very feint misfire.

Logged blocks 15 and 16 and cylinder 2 had a misfire AND cylinder 3.....ARRRGGGHH

Goes into VW on the 31st so they can check the coilpacks as they are covered by warranty. Though might try and run some cooler grade spark plugs as it's remapped and using standard OEM plugs. I know some say you shouldn't need them but other say you should.

Was hoping for bad misfire on 3 so I knew it was the coilpack.....

Will report back end of the week, hopefully it will return so I can pinpoint the problem.

I think the revised OEM plugs are one grade cooler.  (on the Cupra anyway)

I imagine new coils and plugs and the car will be silky smooth again.

Have you used any sh*t fuel recently?

 :ashamed: :ashamed: :ashamed: :ashamed:

Yes.....had to pop in £10 of standard unleaded at sainsburys and an Esso....had a feeling it might be that so brimmed it with Vpower as usual and will plan better in future and not get caught short.

I too was caught short and had to put a tenner of 97 in in!  :sick: :sick:

As you say better planning, I was very tired it was Germany to yorkshire run

Replaced my coil pack in cylinder 4 and everything seems to be better.  I did notice that my coilpacks ended with the letter D and the new one with the letter F.

Presumably, the rev. D coilpacks are the ones known to have an issue and covered under the VW replacement/call back?

Nightmare..

Couldn't get to VW this week as had to manage a night deploy.

So thought I'd swap the spark plugs from 2 and 3.

Took it out and the following errors...6 in total. Fuel low is fine, had 10 miles range left and will fill up later...the rest  :confused: :confused: :confused:

One question is the connectors onto the coilpacks have a couple of clips missing though they always have been. Could it be a loose connection? Is the bracket expensive and what is the exact name for the set of four connectors?

Driving around like Miss Daisy is fine, though as soon as you push the loud pedal then it starts missing in 3,4,5,6....not noticeable in 1,2...weird.

Sprak plug in the 2nd from left was sooty 2nd from right wasn't, could this be just a spark plug issue?

Thanks

No scan yet, will do that tonight I think.

And also it's a Stage 1 map (Independent map - not revo etc)

This morning it was phenominal again, felt like it did after remap...almost forgot.

also my MPG went from the average 30mpg to 33.4  in heavy traffic as well..

Over the moon.
