No power boost. Low pick up. VCds says EGR temp sensor voltage high, inlet manifold runner faulty, coolant temperature circuit faulty, and output Speed sensor of automatic transmission

It sounds like you have more than one problem, first I would check the inlet runner diaphragm and linkage to see if they are all working, next I would test the catalytic converter. Here is the guide

Is the car a turbo?

Please get back to me.

Best, Ken

2)001037 / P040D EGR Temperature sensor high
3) 008213/ P2015 Inlet manifold flap position
4) 008581 / P2185 Coolant Temp Sensor too high
5) 008448 / P2100 Throttle Actuator control Circuit open
6) 001027 / P0403 EGR Valve N18 Malfunction
7) 009254 / P2426 EGR Cooling Valve control circuit
8) 008449 / P2101 Throttle valve Actuator

I hope this helps. Thanks for your assistance. Looking forward to hearing from you soon.

Please clear the codes and drive it, then read the codes again to see what comes up. We are looking to narrow the codes down by doing this.

What is the code that is being set, erasing the code will not fix anything, if the turbo, or boost pressure regulator is faulty this will have to be looked at, but I need the code or codes first to see what is going on here.
