Hi guys.
Checking the lambda with VCDS-lite on my Polo, and the lambda under block 6 (long term fuel trim?) is sitting around -17%. So, the car is running rich?
When i check the lambda under block 1 (the short term trim) its doing something weird: At idle its jumping around the 0% mark, but sometimes when I turn the air-con on, it drops down and jumps between -12% and -20%.
I know when the aircon is switched on the ECU adds fuel to compensate, but this just seems odd?
Polo - lambda VERY negative
