As above, I fitted a boost gauge today nd went for a test drive. Car felt normal but I could only get it to hold at 0.5 Bar (peaked at 0.68) Just out of curiosity I checked the error codes and got 45 which is pressure sensor/pressure exchange solenoid valve. I have found these two above the brass wastegate solenoid but don't know what to do next I had a look tonight but everything looks ok. Is this the solenoid that needs cleaning out with brake cleaner? I have done a search but there seems to be some confusion between the pressure exchange solenoid and the wastegate solenoid.

 

Where have all the experts gone?

Click on reading error codes.

Tells you what the code is.

On the right hand side front wing of the car there is an assembly containing the wastegate solenoid (the lowest one) the MAP sensor (little square black box with one pipe on it) and the pressure solenoid. Sits on the top of the assembly. It's this that needs cleaning.

The last time I did mine, I ended up completely dismantling it. I don't recomend this, as it took me 1/2 an hour to find the spring that escaped...

Connect up the green connectors under the dash to put the car into test mode, and then make with the brake cleaner. There's plenty of threads about this, so use the search function! (Don't worry - it's an easy fix)

 

That's more like it, cheers dnb I did do a search but some people said it was the brass device some said the one above. I actually tried to clean out the brass one yesterday but that didn't cure it (obviously) I'll try and clean the correct one tomorrow
