    So I rest some fault codes 200 odd miles ago due to a mis-fire at Christmas. The fuel trims are now showing 3.4% at idle and -3.9% at "Part Throttle Value". This from vagcom 409 (yes old!) using block 32. I think it is fine but just wondering what other peoples are showing like? The car is very good on fuel, averaging 200 odd miles and still having 1/2 a tank left.

    They are pretty spot on chap, well within spec. The ECU will compensate +/-25% before throwing a fault code.
