Golf 6 2011 1.4 TSI low boost and P0243 error code (CAX engine)

Post by Tradman »

Hi Guys.
My wife has the above car (135,000km)and is giving a P0243 error code on the VAG. I have replaced the N75 solenoid and still have the same error.
I have tested all the vacuum hoses to the solenoid and they're all good. When I drive the car it has almost no boost and very little power. The MAP sensors are picking up pressure in the charge pipe and manifold so I think they're ok. I have cleaned the MAP sensors too. I have also had the ECU tested which is 100%
If you have any suggestions for me I'd really appreciate it.

can be as simple as a blown fuse. have you checked that ther is power at the N75 valve?
