Hi people, have just joined and own a Audi a6tdi quattro auto on a 2000 plate. Owned it for 3 months now. So fae ownership has been up and some downs. Have replaced a seized f/os brake caliper, serviced the car also. The car however still has a couple of probs. 1. Tickover when starting hovers at around 1200, have a new temp sensor on route hopefully will sort this out. 2. It does occasionally run out of steam above 60mph at times, again this is intermittent, power disappears then re appears. A bit disconcerting especially when I was overtaking on a1 on route to Scotland recently. Any pointers would be appreciated. Again hi to all you people.
