My 1998 BMW 740iL periodically shows check engine and periodically the check engine goes off. When the check engine is on it was diagnosed by these 2 codes: 139 and 112.
It was repaired by BMW certificated mechanics however it still shows these codes as whenever the check engine goes on.
Any help is greatly appreciated.
have the same problem?
