After having problems with my 1.8T idling from 800 to 2000rpm and revving on it's own I did some research and thankfully got pointed in the right direction from the loyal Audi-sport members, found out I needed to buy a crankcase breather and pressure regulating valve. My fuel economy was terrible, boost seemed poor and driving the car was really starting to p*ss me off. Picked my parts up from Audi this morning, took the car to Honda where my mate had a free couple hours and got some bits done, dropped oil and changed filter, changed fuel filter and filled up with optimax, fitted a panel air filter after much consideration about an iduction kit, replaced cabin filter, fitted ngk platinum plugs, new coolant/anti freeze. after service parts were done we fitted the crankcase breather (old one was in a state!) then fitted pressure regulating valve, also fitted 2 new coils as I had missfire on cylinder 3 and 4 fault codes. After everything was fitted removed all fault codes and took it for a drive...... The outcome was amazing!! The car has never felt so quick since ive owned it! Really did put a smile on my face, it runs perfect, no engine management light and a great increase in boost! Productive day
