Broken camshaft on (2009 E61)

[Edinburger]

Car wouldn't start yesterday. It's a fully serviced, and until now reliable car, and with no signs of anything wrong. Drove home on Monday and parked.

Car wouldn't start yesterday. Called the RAC who couldn't help and my car was taken to a local garage. They've called me and today said it has a broken camshaft.

I don't know if anything else is wrong with it yet, but I'm waiting on more information. An approved BMW garage said they would look at it but I could be looking at a bill of a few thousand.

Has anyone experienced this before? Anything in particular I should be looking out for or avoiding?

Sure not a camshaft sensor?

If you drove home OK and parked it and then out of the blue it won't start I can't see how the camshaft can have broken.

Camshafts don't normally break even if an engine does physically let go somehow.
