Misfire and Flashing EML

(1/5) > >>

johnhol78:
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?

Tfsi_Mike:
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?

Boothy:
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.

bacillus:
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.
