Hello

Q7 3.0 Diesel is struggling to accelerate on low RPMs i.e. its really sluggish on the get go, and on a steep hill its literally doing 15-20 miles an hour max no matter how much you floor the accelerator. On the flat highway, it'll do 100mph+ comfortably.
These are the stored codes:
P2011 intake manifold runner control circuit / open (Bank 2)
P2008 intake manifold runner control circuit / open (Bank 1)
P2100 Throttle actuator A control motor circuit open

any thought, ideas, help would be greatly appreciated.

Many thanks in advance guys.
