Well it moves upwards half inch ok.
Will have to dig into vag-com, or pop up and see my bmy specialist if he's got the diagnostics for it.
I think air mass meter or that N75 turbo pressure thing are faves from searching about.
Neighbour reckoned he had the samw when an air mass meter went on his audi.

That PM you sent me, one reading went -5, I presume would have been 5 if had connected the opposite?
Also, that's connecting to connector, not meter, so how does this test it?
Not good with electrics.... lol.
Thanks.
