An air leak would cause a low value and cause your trim to go off, too. I was interested to see what the imbalance was like at 2k. Might give us a clue. Ideally you should log the air flow while driving.

I know you havent had you air box off but I had this after Audi replaced my cam cover gasket under warranty, I replaced the MAF seals and all was well.

Have you tried unplugging the MAFs? Doesn't this give a false reading for a while to run ok? Could be talking out my knothole again though.

thanks for all the insight. I need to take it to a garage today really (left all my tools at home) can anyone recommend anyone in the surrey area? I usually take my car to MRC but that trip is just not feasible today, supposed to be driving to Bath later :-(
