P0234 Overboost issue
« on: December 22, 2022, 04:53:00 pm »
Hello. I wonder if you can offer any thoughts on the issue I'm having with my 2.0 TSI Mk5 estate (BWA engine).

For context - It's a Japanese import and I haven't driven it a great deal since it landed. on first driving it would flash the engine light and go into limp mode when putting your foot down. Fault codes at the time saud coil pack so I replaced these on cylinders 1 & 2 (there was corrosion on the end of them).

Now it's still going into limp mode when you put your foot down. All boost drops off around 4000rpm and the fault code I'm getting says P0234 overboost condition. [

I've taken it to a couple of places to look at it. The first place replaced the MAF sensor and this didn't solve it. They then told me it likely needed a new turbo (£1600).I was reluctant to take them up on this as they were talking about vanes sticking in the turbo. I understood this was only an issue for the kind of turbos fitted to TDIs, is this correct?

The second place replaced the N75 valve and this hasn't solved it either.

I've pasted a couple of scans from below. The first is after the first place looked at it, the second after the second place. I've noticed now there is a fault code related to the MAF and one related to voltage. Could it be a voltage issue to the MAF sensor causing the problem? Where would I start in addressing this?

Any help is much appreciated

Re: P0234 Overboost issue
« Reply #1 on: December 29, 2022, 11:24:40 pm »
I've been also getting limp mode and the same error code P0234 overboost condition however have not had any error codes to do with MAF sensor or voltage, I'm planning on replacing the N75 as I have also received an error code for the N75 (P0243 - Solenoid Valve (A) for Boost Pressure Control (N75), Open / Short Circuit to Ground) as well as the diverter valve. If that doesn't work I'm not sure what to try next as a new turbo will be too expensive atm.

Replaced N75 and Diverter valve but still getting the overboost I think the turbos must be finished 😭
