hi all. I've got a 2015 biturbo Cascada (same engine as insignia) that's gone into limp mode and won't regen. My local garage have scanned it and it's showing a p2453 code - "DPF sensor implausible" or something similar. I've swapped the dpf pressure sensor but can't get back into the garage till early march to relearn the new sensor. Is there anyone in the Grantham area with a Voxcom unit (or similar) who can help?
