Audi A3 2.0 TDI BKD Won't rev? No EML no codes

[Audia3aston]

Hi I have a A3 2.0 TDI BKD engine code

It will not rev more than 1200rpm
It will only just reach 1800 with foot to the floor in neutral!  And is also the same whilst being driven.

NO CODES NO EML LIGHT

Timing is all correct all tools slot in fine.
The turbo actuator is moving when I cover the boost pipe,

If I hold foot to the floor it smokes
Can't get my head around it I've un plugged all different connectors to see if they make a difference and nothing improves it or makes it worse,

Anyone heard of or had this problem before? Thanks in advance
