Hi All, I've been offered a C5 estate 2.2 diesel to replace my old Xantia estate. However, as an older car, it comes with issues. I have Lexia 3 on my laptop but before I go trawling across country to check it out, I thought I'd ask here to see if there were any tips to what might be the fault. The C5 is showing faults on screen on the DPF filter & ESP/ASR. I know the DPF filter warning can throw up the service light, but would it throw the ECU into limp mode? I have also known the actuator on the turbo wastegate to produce similar running problems if there is a build up of carbon as the gate then stays open. Any thoughts, please? Handyman
