So had the car back for a couple of weeks now since getting new glow plugs, exhaust manifold and turbo fitted due to DPF and turbo under pressure faults.
While the car had these issues, it was performing a passive regen every 50 miles or so. Since its repair, the passive regens are consistently every 100 - 110 miles. Even if i stop the car during a regen and it fails, it wont carry out the next one for another 100 miles. this is regardless of engine temp/fuel level, which I'm sure I read somewh
