V50 power loss

JimbobLee · Oct 24th, 2018, 19:10

Hi guys, I’m new here and seeking some advice please.

My 2005 V50 2.0d (136bhp) has a massive loss of power. Just after I bought the car a few months back I noticed that turbo boost would dip ever so slightly at around 2000 rpm and then would pick up straight away. Since then the problem has much more severe, I have already swapped the TCV with the throttle body valve which I believe is the same valve? This has not cured the problem. The vacuum pipes coming off the TCV seem to be holding vacuum fine. When driving it does sound as if the wastegate is opened at 2800 rpm and there’s no more power.
I’ve had fault codes read and it’s coming up with TCV valve low signal, EGR faulty signal, fuel volume control valve faulty signal and particle trap pressure sensor faulty signal. Has anyone come across this problem before before I start ruling things out?

Any help is much appreciated TIA

did you wipe the errors and went for a test drive, to see which ones return?
