Hi
My auris 2.0d4d has started having problems on a cold start. At the last cold snap car refused to start. I called the aa out and they got it going, accompanied by a puff of blueish/grey smoke. Dealer checked Battery and determined glow plugs to be at fault. Replaced under extended warranty. Car been ok for a few weeks until last night, started on 3rd attempt and same again this morning, again accompanied with blueish/grey smoke that stops once car is running. Warm starts ok, Oil levels good, pulling ok and getting usual fuel consumption. Car booked in on Weds for 50k service. Any ideas what's causing this? None of my previous diesels have done this. Thanks, Gareth.
