Re: Turbo overboost
Boost does vary. But electro valve makes loud humming noise. Bought a second hand one off ebay for 14 pound. With guarantee. If that's the problem. And it sorts it. ill buy a new one.
hope i can delete fault code after lol

Re: Turbo overboost
Anti pollution fault and then ESP fault was what I used to get. Shows how useless the anti pollution warning is to the ordinary idiot.
Really the fault should say "get on a lexia, which is something a Citroen garage has"

Re: Turbo overboost
You need to check the wiring going to the air pump, the control solenoid and also test both parts. If there is no fault found with any then the ecu is all thats left.

What air pump would that be ? Are we talking about a 2.2 HDi here ?Jabo wrote:You need to check the wiring going to the air pump.
Re: Turbo overboost
Can actually only find reference to one of those air pumps in petrol Citroen engines. That's a stupid error code to display for a diesel.
