Hi gents,
Need some help with my audi S3 8v, the past 2 weeks been receiving the below error code:
Fuel control system 2 (bank 1)
(P21F9) too rich at idle
For the past 2 weeks the car starts Normal on cold start, but if I switch off and try starting again it does not. Have to crank a couple of times then it starts.
Did some research and replaced couple parts
PCV
O2 sensors
Injectors
Intake temp sensor
Checked for air leaks etc
Yesterday I noticed that if I remove the dipstick or remove my silicone hose to my boost tap (creating a boost Leak) the car starts immediately on the turn... Any idea what it could be? Seems like the car is choking or something
Regards
