Customer Question

I have a BMW 520I, 2004, recently it has starting problems, sometimes it will start immediately other times it will turn over and fail, usually though it will then start, however when it does the rev counter seems "flickery" and it seems sluggish.
however when it starts first time its driving perfect ?
It has a new battery, full oil/filter change etc.
any help appreciated.

So is this fault primarily when its hot?

Any warning/engine managment lights come on when it fails to start?

How do you mean the RPM counter flickers? sweeps round the clock and back or just jumps?
