Hello,
I have c4 1.6hdi hx engine. My car has no power at low revs hardly can get up to 30mph. Turbo is spinning freely, vacuum is ok . I change the vacuum solenoid with no luck. It is not the egr as I blank it just to check this and same issue appear. No change after unplug maf and map sensor. There is no fault codes stored as well. Car is serviced recently with new oil and air,fuel and oil filter. I am running out of ideas what it can be. Please if anyone can help.
Thanks in advance.

And I forgot to mention when I do unplug maf or map sensor it doesn't throw any fault codes for some reason wich is a bit strange for me

Are you using a full chip Diagbox to read the ECUs? If Diagbox, what version of software are you using?

Hello Paul-R,
No I haven't got Duagbox. I check it with Snap on solus and delphi diagnostic tools. Nothing on both. It feels like air or fuel supply cuts off. On fourth and fifth gear is running OK, first to 3rd gear hardly I can get to 30mph.

I'm no expert on these things but that doesn't sound like a PSA error code.

If anyone is Interested, I found the problem for my power loss on 1st to 3rd gear. Turn up to be bad clutch switch. Since I disconnected the clutch switch the power get back and car is running mint.
