Hello everyone ,
I purchased my 2009 A5 2.0 tfsi last September and have had issues with it since day 1 lol . It is a CDNB with 150k on the clock . When I got the car it had a few mods already but had trouble starting properly . So let's go 馃檲 here is what I have done so far in order :- replaced fuel pump control module , PCV , MAF ,air filter ,coil packs , plugs ,removed forge BOV and gone to stock diverter , the car ran ok ( still not right ) and I started getting running rich codes so replaced the hpfp and 02 sensors which seemed to cure it . Now I'm getting air intake leak codes and idle air control code where the revs fluctuate at idle upto 1300 rpm and settling to a steady but rough 725rpm . I today replaced the n80 to no avail and have ordered both intake solenoids ,one at rear of engine and the other is below the flap potentiometer on the intake manifold .
has anyone had similar rough idle issues and how did you cure it 馃槈
Thanks

Yeh I'm thinking that's my best option at the minute 馃檲 I'm only using OBDELEVEN pro , thought it was a decent choice at the time 馃え . It perhaps could be if only I knew what I was looking for 馃槀馃槀

The setup worked a treat , though not quite the result I was hoping for 馃檲 .Smoke was only coming out from where the starter motor mates to the bell housing , to me that only means one thing 馃え rear main seal ... I did do a short video but left the phone on for a period (in paused mode ) while I was climbing about under the car and it died so the video was lost 馃槀
