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.

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.
