Hi, I'm a newbie who is experimenting whilst off work.

Hopefully, I will be able to post my experience soon.

I have a Peugeot Expert Tepee that I brought back from Spain with me. Its been a real pain over the last few years, and has the EGR light on.
After someone (allegedly) repairing the ECU, I still have the light on.

I have done a thorough check off everything, and the problem is that the ECU is pumping 5v out of the wire that should be monitoring the EGR.

My plan is now to find the EGR map and remap it and switch off the corresponding DTC switches.

Its been a bit of a learning curve so far, of which I will write up later when I have a conclusion.

Now, how can I identify the correct map.....?

Thanks to the information on this site, I have been able to get through some of the problems, hopefully, I will be able to get the final bit done today!!!!
