Okay, so I finally got around to checking the new codes after clearing the old ones more than a month ago - good call latief!

The only codes that came back are #5 on the DM (EGR faulty) and #13 on pin 8 (O2 control system operating at rich or lean limit). So it looks like my problem is in the EGR system.

I'll do a forum search and see what turns up, but if anyone has any suggestions in the mean time let's hear them!

Best Regards,
Rob
