Yeah perhaps, I'll take another look. I was performing a U-Turn and mounted a curb (a left over pedestrian crossing from roadworks in the middle of the road), the loudest thud was on the inside of the rear passenger side wheel, so around the exhaust area.
That specific code however, it originates from the EGR, the one you mentioned near the firewall of the engine bay, correct? I think smacking that on a curb would be near impossible but I could be wrong. But if that code could be flagged due to the exhaust crumpling or something similar that would be understandable.
Appreciate the help, I did use a DPF cleaner about a month ago, assuming that covers the EGR too.
