Iv written a few posts on this forum about my first BMW as its doing strange things and I don't know what to do, basically within a week of buying it iv noticed it does strange things like throw up faults every now n then like fuel pump, transmission, dynamic steering, only when I go to start it, then its fine 5 mins later and they all vanish. Never happens while driving only at start up and even then only somethimes.
Diagnostic at garge said glow plugs and air flow faults which they cleared. There is also a sucking noise, like air being sucked/ejected between 1500 and 2500 rpm, loads a power though and garage said its definitely mapped and very hard.
Don't know what to do about this stuff, any suggestions, leave it to Bavarian maybe or should I find a good auto spark in Belfast? Wondering if iv bought a nightmare, apart from that the car looks and drives 100%.
Any ideas re what could be causing this stuff would be brill, can these things be fixed or are they generally a nightmare to sort?
