These would stay open, not allowing the engine to reach the required temp for a regen. There was no temp gauge and no DPF regen indicator, so people were completely unaware of what was happening. Until fuel consumption went up and the engine struggled at high revs.
I would like to think these issues have been prevented on the F30 series.
Good point about the thermostats failing causing no regen on the E90. Are the F30 thermostats any better? We should have idea now the cars been out 5 years!
