To standard and now back pressure is showing a value around 9mbar in idle.
Is there anyway to easily tell if the dpf has been gutted, as it’s definately not a replacement pipe?
Thanks

I guess my first check would be to have a look and see if it looks like it has been welded back together at some point.
What sort of millage is the car? If it’s higher millage then I would think it would be a higher chance it could have been gutted due to issues with it clogging up in the past.
