Car is running very lumpy on idle, only once car has reached
operating temperature though, done every logical check i can think off
but still no luck. Need desperate help with this as the car is my daily. these are the results of what i tried tonight with vag com and at what time intervals.....

19:49 - Car mildly warm, reading 55 on temp gauge. Seemed to
take longer to start than normal, no misfire counts

19:51 - Pulled away and moved the car 100 meters up the
road, car sounds lumpy at idle however no misfire counts through VAG Com. Temp
at 75 degrees.

19:53 - Again, drove 300 meters no misfires or signs of
hesitation.

19:57 - Normal driving, misfire counter reading misfires on
cylinder 4.

19:57 - When pulling away extreme hesitation and misfires on
cylinder 2 and 4, engine management flashing.

19:59 - Pulling away, feeling of boost issues, possibly limp
mode but with no engine management light.

20:04 - Excessive misfire counts on cylinders 1, 2 and 4
when accelerating.

20:17 - When at idle cylinders 1, 2 and 4 counting misfires.

20:19 - When building up the revs again excessive misfires
across the board and flashing EML.

20:31 - Excessive popping and banging on run down from 4,000
rpm.

20:36 - When driving briskly misfires only been counted on
cylinder 4.

4x Plugs Changed

4x Coil Packs Changed




No fixed EML present on dash.






I also currently have no brake lights working
but all bulbs are fine and have not blown as rear lights work with
dipped beams on but do not light up once brake pedal is pressed. Could
this be an earth fault somewhere??
