Hello Everyone, My names Eddie and I'm new to the site
I was wondering if anyone could help i have just bought a A6 2.5 Tdi which has been parked up for six months and only ever done short runs in it's life 80000 mls Mreg
she starts perfect but won't rev over 2000 rpm and smokes out the street, miss fires but once you go back to idle all is well again runs fine.
there is a knocking noise from the air flow meter at idle this is the air position flap inside it opening and closing really fast and hitting the closed stop if i disconnect the air pipe to the valve beside the air box the noise goes away flap sits half way open.
i have put fuel cleaner in the tank and replaced the air and fuel filter also adding cleaner directly into the fuel filter when i fitted it, didn't help
i've taken off the intercooler hoses and the intercooler looks extreamly black but it is allowing air through it.
is there a sensor i don't know about or could it be a turbo issue or is there a blockage in the air intake somewhere
any advice would be really helpfull and well appreciated
i thought i had a reasonable knowledge about engines but this ones got me stuck
if you can help i would be extreamly greatfull
thanks ed
