No power a6 2.5 tdi v6 180bhp quattro 2001

[robbobjm]

Hi I have an a6 2.5 tdi v6, I'm having problems with it having no power, the only problem I had was a broken map sensor on vcds the AIT was 127c and no boost pressure, I changed it for a working one and that solved that problem, now i have no codes, fuel pump timing in spec, struggles to rev when cold then revs fine when warm but still no power. Anyone had this symptom before?

Sounds like the auto choke flap in the intake manifold, you hear it operate when you turn the key. Changed mine the other week after messing with just about everything else first... Not sure where you would get new from, but first check that vacuum pipe is not collapsing due to deterioration

Fault codes?
