I have a 2003 BM compact, 318 Ti Se petrol 1.8. When I drive it it cuts out for a split second or sometimes stops and both times the red battery light comes on along with the yellow traction light. The odd time it turns over and doesn't start first time but starts second time. It's been on the diagnostics comp 3times, 1st time a problem with cam shaft sensor, 2nd time an airbag problem and 3rd time it said cam shaft sensor and crank shaft sensor problems. Any1 any idea what's the problem and would it cost much to fix?
Oh by the way I know nothing at all about cars!!! Thanks is in advance
