But having found no quick fix adjustment, the vehicle remains stuck at the dealership pending authorisation from Vauxhall to undertake more extensive warranty work.

Report of 2016 Vauxhall Astra 1.6CDTi 136 going in for emissions update and on the way home the low level oil warning message came up on the small info screen. Driver stopped the car and dipped the engine oil, it was full. The message still comes up approx twice a journey despite the engine oil being on the top mark of the dip stick. Perhaps it's really indicatiing a malfunction of the diesel post injection system that is supposed to fire off active regenerations but is instead sinking to the sump and this is a high oil warning rather than a low oil warning.
