It has been an eventful few months for our long-term Audi A6, because while I mentioned the laggy gearbox and chipped windscreen in my last ‘Our Cars’ report, I haven’t yet discussed a more serious issue that has been affecting the performance of the A6. It started off with an adaptive headlight fault message on the instrument cluster, despite the headlights appearing to work perfectly, and continued with warning messages for both the adaptive cruise control and front assist. But these messages all appeared to be red herrings and so they didn’t really phase me.
Then, arriving back home in Birmingham after a drive up from Luton, as I went to pull away from a set of traffic lights, the engine felt and sounded lumpy, as if it was struggling to continue to run. Squeezing the accelerator seemed to solve it for a short while, but then the same thing happened at the next set of lights. By the third junction, I was expecting an issue, and an instrument cluster message popped up saying ‘stop/start deactivated, please start manually’. With my foot on the brake, I pressed the start button and the engine fired into life, but then instantly cut out. This happened a couple of times more, but then it managed to start on the third attempt. All was well for the rest of that evening, and for around a week more, but on a road near Hadrian’s Wall, the engine cut out during a manoeuvre and the A6 temporarily blocked the main road. Following this, the A6 cut out a few more times, but started again fairly easily, until on a trip to Wales one night and the accelerator suddenly failed to respond. The engine had cut out as I exited a roundabout, so I coasted as far away as I could. But with high kerbs at either side of the road, I ended up sat on the tarmac for around 15 minutes before the engine would run again.
I called around the local Audi service centres to attempt to book the car in, but found that they all had a waiting time of three weeks to a month for customers needing a courtesy car, suggesting they don’t have enough of them to go around. When its slot finally arrived, the A6 spent three days in the workshop for the fault to be diagnosed and fixed; with the solution being a strip down of its wiring to replace corroded wires. This seems like a strange fault for a car less than a year old, but pleasingly, it seems to have solved the cutting out and error messages, so fingers crossed it’ll be plain sailing with the A6 from now onwards.

Attractive 19-inch wheels, a decent profile tyre, and the A6 rides pretty smoothly.
First the boot carpet, now one of the runners for the retracting roller parcel shelf has broken.
