P0021A Camshaft Position - Timing Over - Advanced or System Performance (Bank 2) P0065 Air Assisted Injector Control Range/Performance. P0068 MAP/MAF - Throttle Position Correlation. P0072 Ambient Air Temperature Sensor Circuit Low. P0075 Intake Valve Control Solenoid Circuit (Bank 1)
Sorryfor reviving this topic, but I need your help. I have Audi A4 B8 2009 model, with 1.8 TFSI 160 hp engine (CDHB engine code). I'd like to check the condition of the timing chain and tensioner. I did try with OBDEleven and VCDS, unfortunately without success. I cannot find anywhere this positition - Camshaft adaptation intake bank 1, Hereis how you can easily test both your crankshaft position sensor and camshaft position sensor. It's very important to be able to test these sensor since xxU4WB.
