So, yesterday my car jumped into limp mode (Engine light, VCS and Traction Control light) and didnt want to budge. So I nursed it home and parked it off. This morning, I plugged it into a scanner and it threw up P0400, which was a EGR fault. I cleaned the EGR out and then wiped the codes and went for a drive. I drove for around 2 hours until the car went back into limp more. Got it back home, plugged it in and then this time I got a P2002, DPF.
I removed the DPF, cut it open and emptied it and sent it for welding. At the same time, I manufactured a temporary EGR blank and applied it. I got the DPF back form the welder, refitted it and cleared the codes.
My problem lies here, reading about removal of the DPF contents and blanking the EGR should throw up codes and limp mode but it hasn't, Why hasnt't my car broken down again.
I will say, my car has not had the DPF deleted from the ECU nor has the EGR (otherwise I wouldnt get P0400 and P2002)
Can anyone weigh in any ideas or comments because I am baffled?
