Hi all
Has anyone had this same issue please?
I noticed the engine management light come on this morning on my 2014 A6 3.0bitdi on the way to work and a considerable loss of top end power with the engine unwilling to rev freely at the top end of the rev range.
Scanned with VCDS and the two following fault codes came up:
The second fault code (12291 - Energy Management Active) cleared putting out the engine management light out but the Intake manifold flap fault code remained with the same loss top of top end power on a following road test.
If anyone has any ideas or has experienced the same issue I would be grateful for some advice to fix as soon as possible.
Thanks in advance.
