I have a 2009 Audi A5 (B8) 3.0 TDI Quattro sport in Manual.

I have noticed turbo lag and now it's going higher and higher in the revs before spooling. Its almost up to 2.5k before kicking in and the car is not pulling as it should. Its almost like driving it in limp mode until it kicks in.

Has anyone encountered this issue before? Any advice really appreciated

Regards

I haven't encountered it, but a scan might help if it's a sensor gone bad.

Otherwise, it could be a boost leak, can you hear any hissing noises?
Turbo on it's way out.
Dodgy turbo actuator - they are electric on these engines.

Could be a number of things that need checking out.
