Audi Idle Misfire and slow acceleration in first gear

[Tom Norman]

Hi there,

I bought a 2009 Audi A6 s-line 2.0 TDI manual transmission last week with just under 80,000 miles and have had numerous issues since buying it. Unfortunately It seems I got this from a dodgy private sale. The car misfires when idling and up until around 1500 RPM. This is not always constant and occurs every few seconds when the engine is cold but when warm it gets a lot worse and is pretty constant. I am also having another issue whereby pulling off in 1st gear is painfully slow despite revs being high. As soon as second kicks in then acceleration is strong again with the turbo kicking in. I’m unsure whether the two are related at all but would be hugely greatful for any advice and possible causes.

Many thanks.
