Hi guys, just wanna say great forum by the way - so much info on here!
Got a small issue with my 02' s3 - whenever it has a cold start, it coughs and splutters for a few seconds, then idles fine.
All starts after that are fine, but I noticed under hard acceleration with wide open throttle, it has a very small miss that is like a soft
Rumble, and it only happens sometimes - which led me to the conclusion that it was the haldex slipping (being new to Audi ownership) initially. I decided to change plugs using a NGK pfr7e plug gapped at .028". For 2 months the miss disappeared but now it's back, but the cold start issue was not fixed by changing plugs. Anybody have a similar issue? Or perhaps could share their opinions on what I could try, I'm in a small town with no access to vag-com for the next few months at least.
The car is modified with APR tune (195kw) and has an upgraded haldex controller. It is always run on 98 v-power.
Apart from that it is a fantastic little car. If I can fix this it would be tops!
Thanks in advance,
