C5 HDi - no boost.

[Northern_Mike]

Driving a 2006 C5 HDI 16 (2.0) today. Nice car. No boost. No rattles or smoke, highish miles.

Duff wastegate electronics? Faulty electrovalves? Any ideas?

Could be one (or more!) of:

MAF - check air flow on Lexia
Vacuum leak - although I would have expected this to show up in poor brakes
Blocked vac pipe to the turbo actuator - if you can get to it, check that the vanes move smoothly, and return back to rest quickly
Seized vanes in the turbo
DPF blocked

Thanks Richard!

I can, for a few hours today, pop round with the Lexia. After that I (and my laptop) aren't available until the end of the month.

Go on then. I'm at BB4 6LX

Ah, right. That rules that out then.

Thanks for the offer in any case James. I have actually bought another netbook so I can get my Lexia running again.
