Hi,
I have the code U1208 appearing on my diagnostic tool and I can't clear it. I also have the warning on the dash "engine fault repair needed". I have looked up a number of threads but nothing conclusive has stuck out. Anyone have an idea of what this could be?
Recently I have had the timing chain and associated guides replaced. I have also had the Turbo replaced.
My thoughts are:
Oxy sensors, OR
Build up of carbon over the intake valves, OR
Spark plugs (they are Iridium and only 15k old), OR
Cat converter.

Really appreciate anyone's input.

Hey Bathey, a quick search pointed to spark plugs as a common result:

Peugeot 508 U1208 Engine Trouble Code - Peugeot 508 U1208 OBD-II Diagnostic Network (U) Trouble Code For Peugeot 508 | EngineTroubleCode.com

Another suggested o2 sensors..

Hope that helps.
