vw passat p0299 fault

[ciaran13]

Hi I have a sept. 08 vw passat 2.0tdi sport. The problem is that it feels dead and when pulling up a hill it will loss more power and the heating coil light will come on. The fault I am getting is P0299 turbo under boost. I changed the N75 valve but no good. The problem seems to come in over 2000 rpm. Also it seems to be a electric waste gate valve ( would this be right).

The engine is a 2.0 tdi (140) CR type

Many Thanks

It's a common fault. The turbo actuator, what you called an electric waste gate valve probably needs renewing. If you get a proper code read it will probably tell you that. P codes are poor for diagnosis.
