TT misfire after exhaust replacement.
Discussion
Hello all,
picked up my freinds 225TT yesterday for him after the exhaust fell off, aparently it ran rough as he drove it to the garage, one assumes it would be the lambda sensor playing up & maybe putting ecu into safe mode?
it seems now that it is running on 3, i had a quick look last night in the dark but couldn't really see any thing of use, ie sensor plug off or anything?
would this be normal for this engine & would we need to reset the ecu?
if so, how do we do that, remove battery terminals & short out leads?
any help appreciated thanks.

Don`t have HT leads, just coil packs which do go wrong.
Read the fault codes! Otherwise you will be urinating into the wind.
The fault codes will send you to the correct cylinder that is misfiring or the oxygen sensor that is faulty.

vag.com is what you need to scan the car's ecu for fault codes
quite a few owners have it as audi will charge approx £50 to do this for you.
Coil packs are your first port of call, if your friend doesn't have a spare already, try switching them over (cylinders 1&2 are easy enough to get at)
