[chezzer]

my x5 diesel suddenly wont start only occasionly in the mornings but now wont start at all aa seems to think its the crank sensor common fault?

[tgr]

you'll need to give more info. Is it dead or does the engine turn over, for example?

[chezzer]

hi yes turns over fine was using it everyday fine then broke down in town centre the aa came out tested it couldnt find anything on screen etc but started ok with carb cleaner he says it might be crank sensor possibly?

You need to read the fault codes and go from there, this could be caused by various things.

How hard is it for the AA to buy diagnostics?

It may be the crank sensor, it may be the pre-supply pump.

[chezzer]

Why don't you call out the BMW Assistance or is your car not covered? They carry a full diagnostic kit to read all the fault codes etc.

well so far so good with it had a bmw tech of mine run it through diagnostics and came up fuel pressure issue so he replaced a fuel relay which looked damaged by heat so fingers crossed its been fine
