C5 HDi - no boost.

Post by 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

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.

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.
