Getting the
above BMW fault codes do not necessarily mean it is a serious or hard code.
Sometimes it could be erased first and then re-tried again to make sure if the
original code is permanent or not. A lot of the common BMW OBD1 fixes are based
on doing the basic engine maintenance requirements. Sometimes, garages are
using the most common fixes available on the vehicles repair database which are
usually stored in garages or vehicle's manufacturer's files.
