Ive got a mk4 1.8 sport.
EML came on but only when the engine was hot, dosent come on when the engine is cold. Used the "paperclip" method to check the codes and found out its the MAF sensor. Replaced this for a new one but now i cant reset the ECU!
Ive tried 2 methods as found on this site.
A: turn the key on so the lights go out then off then repeat 30 times
B: disconnect the battery for 30 mins
Neither has worked.
Any sure fire methods anyone can help me with?
Thanks in advance.
