Hi Folks,
Quick question - my 156 THP keeps dropping into limp mode.
I have a Launch 529 OBDII reader and when the scan is complete it asks me for DTC vehicle make but Peugeot is not an option - I tried Citroen but got nowhere. Ford seems to be the only marque that works and I'm not sure if the code numbers are the same.
Perennial codes are P1303 EGR and P0327 Knock Sensor. Fitted a new battery just in case, but to no avail. I think there was a boost code somewhere today as well but I just cleared it and went out for another blip.

I never have to plug the 308SW in but the reader works on the 306 and the 206 (although there's not much to read there!).

Does anyone know if these codes relate to PSA vehicles before I start ripping stuff out.
Limp mode sucks - any help would be greatly appreciated.

Cheers and thanks for looking :)

P1303 relates to EGR calibration fault possibly needs cleaning or replacing ?
P0327 Knock sensor bank 1 can mean timing or combustion issue?

Thanks Pedro,

I've been looking at a few Peugeot / Citroen only readers - I think that is my next purchase, I've been chasing fault codes on this thing for eight years! I think it's time it found a new loving and patient owner!!

Cheers for the screenshot, good reading :)

One more question!

Does a petrol have an EGR? Thought it was just the diesels?

Help!!
