hi,
does anyone have the same misfire issue on GTI pirelli model on stage 1
cant seem to solve this problem.
-
Have you scanned the car with vcds for fault codes?
-
Can you please describe the symptoms
-
FSI 2.0T engine ?
-
misfire on cylinder 3 only all the time, when check code. after stage 1.
plugs and coilpack change not the issue. car works normal.
just that full throttle , sometime engine light flashes.
many of the pirelli ed have this problem, not sure if its the engine or the tuning?
-
plugs and coilpack change not the issue.
Use the search function for 'PCV', 'MAF', 'DV' or 'rough idle' to return some threads where similar issues have occured?
The DV is especially prone to fail. An upgraded revision 'D' DV is deffo worth the cash £46ish from a stealer or a pukka £100+ Forge Motorsport one.
Your fault sounds exactly like my misfiring problem. I've had the throttle body, and a coil pack changed and it hasn't fixed it - an OEM PCV and DV are next on my list.
Really, to find a decent Independent garage near you, is your best bet. My chap does diagnostics for nowt. :laugh:

which light flashes? you sure its not the esp light as that will flash when full throttle especially on stage 1 pirelli/ed30 with the current road conditions
what remap you running?

Sounds similar to many other ED30's/Cupra's/S3's/Pirelli's after 57 reg.
There was an issue with these cars getting the wrong valve springs (Black and yellow=wrong type).
More info in the link below about flat spots etc. Tends not to be the tuning as different types of remapped cars are all suffering similarly.

-
what does your giac dealer say?
have a read of this : reply number 49 : http://www.mk5golfgti.co.uk/forum/index.php?topic=933.msg100423#msg100423
chap with a pirelli who installed revo stage 1 and was also experiencing misfires - it seems the map for the ed30 does not work quite so well with the pirelli edition - revo tweaked the map and I now believe everything is working well no misfires
so if you have a generic ed30 giac map on your car then this might be causing the issues
-
waiting for the reply from usa giac to see what wrong, anyone can confirm that is the valve spring issue or map?
