Hi from a guy new to BMW's having just purchased a 2002 320D SE Touring for the wife. We have had it a few days and drives lovely but need to sort out a few things and to double check we put our fault code reader (from work) on it.
Got the following codes:
112, 4212, 46E3 & 4B90
112 = airbag fault (switch under seat faulty) - knew about this + SRS light on.
4212 - No.1 glow plug open circuit (was on service sheet last year as fault - has someone just taken wire off as glow plug w/lights not coming on when cold)
46E3 - internal fault ECU
490 - fuel rail - running rich
Can anyone throw any light on these last 2 - bit worried about these.
