1. You were DRIVING and it died. DO NOT focus on 'why wont it start'. IMO it isnt a starter failure- starters dont die while driving and dont stop a running car.



2. Dealer is full of shite. They are lost. It is IMPOSSIBLE for a bad CAS to create an intermittent start issue. (A bad CAS will also not stop a running car.) Tell them you insist they do a PUMA for this and give you WRITTEN confirmation from BMWAG. DO NOT BELIEVE WHAT THEY SAY.



3. You need someone to look into your high pressure fuel pump. Is the fuel pump working? Is it generating the required pressures and holding this????




edit...OP is in Australia. BMW dealers are bad, but really bad the further from Germany you get..... in the US, their diesel service is horrific. Maybe in Oz it is slightly better? But they are bad. My guess is they have a car that wont start, and are only focusing on this.
