Code p0299? under boost

The error code P0299 indicates a potential issue with the turbocharger or supercharger underboost condition.

The wastegate actuator is sticking a new one is on the way to replace and hopefully that is the fix. Could the leak from the gear box also contribute to the lack of boost?

I don't think the transmission leak is from low boost, good find on the problem though, let me know if that fixes it. Please start a new question for the leak. Please post your new question here, you must be logged in.

New actuator arrived today and is fitted. After a nice motorway run all seems fine and engine performance seems to have increased. so hopefully that has worked.

now onto the transmission leak... grr

Alas, it wasn't the actuator after all still have the same error code coming up. The leak also isn't from the transmission, it appears to be coming from the throttle body either from one of the hoses or the actual assembly itself. Could this cause the P0299?

I don't think so, can I ask if you changed out the boost sensor?

Caved in and took it to the local garage. Turns out the throttle body was full of oil and also the pipes going into it. Going down the replacement turbo route.

Glad you could get it fixed, thanks for letting us know. Please use 2CarPros anytime we are here to help.
