Hello, I have the impression that at about E50 my TSI is off work, after about 80 km the MKL comes over it. Have the test times deleted, but came back after 50 km. Lamda still fits. The question is: does the error cause something to the engine control? Otherwise the engine runs like usual: slightly tilted idle, rougher running noise while accelerating and feels a bit rutty acceleration (as if always controlled by the control unit), otherwise everything is ok. what kind of fuel to fuel or to add more gasoline to the next tank? Or can you basically ignore the lamp because Lamda and exhaust gas temperature are ok? Thank you.
