A6 DPF Query in Audi A6 (C7) Forum Posted January 28, 2021 I have an Audi A6 ultra 16 plate. Not sure if any one can guide me. problem: car has stopped regenerating, only can do force regen via diagnostic start/stop not working car goes in limp mode when driving a slight uphill (randomly) sometimes it does it and sometimes it doesn’t. I have had car fully serviced gearbox service (oil change) no faults showing on diagnostic no engine management light or any other warning light. I’m stuck with this confusing problem. egr valve is working ok boost pressure showing correct reading not sure wether this has anything to do with dpf?
