OK a further update on the above problem. Started the car up yesterday afternoon, dashboard temp indicated 9.5C. I was about to pull off when I had a phone call so I left the engine running as I took the call. Within 2 minutes I was sitting in the car surrounded by dense white/grey oily smelling smoke which was coming from the aux heater exhaust. I got out of the car and stood by the N/S/R door and there was no jet noise. I'm assuming the blower isnt working at all. Any thoughts before I take the vehicle to Frauds for a check ?
