Hi ,
i have 307 2.0l hdi sw 2004 plate.

car lacks power and can't hear turbo - peugot planet diagnostic c/o and shows 2 permanent faults
1/ engine ecu-permanent fault -turbo pressure-turbo pressure measured too low
2/ engine ecu- permanent fault - egr air circuit fault airflow measured less than recommended.

have physically checked vacuum pipes - all seem ok
have noticed some oil in intercooler although there was evidence of this before turbo stopped working.

peugot garage have had car for a week and say all is ok / normal !
local garage have agreed turbo is definatel not working.

I am looking for any ideas as am myself an engineer and can do most tasks,
and also looking for an experienced peugot mechanic in south cambs/north herts area sg85ht.

Thanks

Ill second what is said about the solenoids in this thread. I had the same thing a few weeks ago - i didnt have the egr fault, but the 'turbo pressure measured too low' was there. I spent ages trying to find leaks, sucking on vacuum hoses etc etc, then replaced the solenoid that provides the vacuum to the wastegate, back to normal :) There is 2 solenoids, im not sure exactly the purposes of the other one, but i wouldnt be surprised if one or both of these failing would bring up the egr fault as well.
