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 🙈 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 😉
Thanks

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

I plan on doing a diy smoke test tomorrow weather permitting , using smoke pellets and an low pressure air pump 🙈 anything to save the £ at this point . Any thoughts about this ?

I will do a short video and some pics ✌

The setup worked a treat , though not quite the result I was hoping for 🙈 .Smoke was only coming out from where the starter motor mates to the bell housing , to me that only means one thing 🤨 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 😂
