C3 Aircross 1.2 Puretech Error Codes

Unread post by Andy53 »

Hi, had the timing belt changed 2 weeks ago and since then I keep getting the 2 engine management lights come on and he service spanner. The garage that did the timing belt have no idea what is causing the errors:

P003C [0x003C]
Intake camshaft profile control A, bank 1 - performance or stuck off
Status: Confirmed
----------------------------
P005A [0x005A]
Exhaust camshaft profile control B, bank 1 - performance or stuck off
Status: Confirmed

Any idea would be welcomed what to look at.

Looks like they might have bodged it. The codes seem to be generic OBD II codes and not PSA codes. It really needs a proper diagnostic with Diagbox to get the proper codes. These have a Wet Belt system, so maybe likely something isn't right with the camshafts / positioning when they refitted the belt.
