Its a 330D E46 from 2004.

The CD is OK, and its only sometimes the problem appaers, usualy when it hasent bee used in some days.

Today i wouldent start, i tryed to turn of the car af few times on my trip, didnt help, and after a 1 houer drive i parked the care fore 20 min. and when i startet it again, there was no problem.

How do i "reset" the boot sequense? and why does it make that error?
