Can't accelerate on incline road

[zap]

Hi

The incline up the road is about 20 degrees up. Accelerator pedal is pushed to the floor but rpm remains about 3-4k, DSG stuck at 3rd or 4th gear. No boost. No engine warning light. No vagcom error.

Flat road is as per normal.

Car is stock.

What's going on?

Tks

So on a flat road you can mash the pedal and the car accelerates and hits the requested amount of boost with no problems, but on an incline it drives like poo?

You have no boost at 3K-4K? Does the car accelerate when you hit the paddle to shift down one gear?
