Hi, I have a similar problem with loss of power. It started 29/08/24, the car drives fine but is in limp mode with the coil flashing. There hasn't been s DPF warning light although 3 mechanics including Audi, say the DPF is blocked, £800 for Audi to tell me that. Audi said it needs a new DPF (£3500). The problem I have is how long would a car run normally with a blocked DPF, by the end of this month it will be 4 months and as I said, everything works as it always has. fine. My Q5 is 2011 3.0 and has only done 85000 miles. anyone out there had the same problem? Many thanks in advance.
