I bought a (05 plate) 5 series E60 525d sport on saturday. Today after taking it to a garage with a fault i find out in needs 4 new tires, my own fault for not check them properly, but 1 has a nail and the others have wear on the inside walls, so i didn't notice.
the main issue is, 3 times it hasn't started. the started sounds like its motor is working fine, but the engine will not started up or even turn over, nothing whats so ever.
3 faults then appear on my i drive screen. traction control, cruise control and fuel pump. After leaving it half an hour its starts fine with no fault showing. When driving everything seems fine.
i've been told it may be a power management relay, or engine management system issue.
it's at garage right now and they've no idea what it is, as it's currently behaving it's self, typical! So they can't identify a problem which they can't see.
if anyone has any useful info it would be great.
Christmas is cancelled this year!
