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?
