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?
C5 HDi - no boost.

Re: C5 HDi - no boost.
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.

Yes, I am paranoid, but am I paranoid ENOUGH?

Ah, right. That rules that out then.
