I had a play with my IID tool today, and without the engine running, the MAF sensor for bank one reads 24960 [ gms or something]. When I start the engine it goes to about 60,000 at idle. Bank two shows zero, but I understand that is the secondary turbo feed.
Surely it should read Zero with the engine not running.
Any of you technical guys with an IID tool able to check their reading with the engine stopped would be gratefully received. I think I'll swap the sensors over to see if it changes which bank is reading high when I get the time. Thanks Kev. p.s. there are no fault codes being shown.
