Wondered if anyone has any ideas. 2008 2.0 sline A3. 210000 miles. In very hot weather the dash & Aircon/blowers lose power soon after ignition when driving and that is sometimes followed by the engine cutting out whilst driving. Left for 10 mins it's ok to start again and the dash will lose power again but after the first engine cut out or 2 the engine doesn't cut out again. Thanks
