Issue of 2011 F10 DME(MSV90)
To our great seniors
My vehicle is 2011F10 N52B25. DME(MSV90) reported the following errors 134b02,133901,133204 Valvetronic servomotor short circuit was shown as an error. Valvetronic servomotor has been replaced with a new one. However, the error still exists. （The engine does not start.) Unplugged the Valvetronic servomotor connector, but the short circuit error remains. Has anyone had a similar experience and do I need to replace the DME? Any comments would be appreciated. |

You should also check the wiring before replacing DME

Many issues with these DME's.
Once you open it you usually see a leaked capacitor that damaged the board. |

RE: Issue of 2011 F10 DME(MSV90)
To great seniors !
This is the update after that. The MSV90 is back from repair. All initial errors are gone. And I learned the valvetronic motor, but the engine does not start. Crank does. There is spark coming out of the plug. Gas is coming because the plugs are wet. The engine will run for about 0.5 seconds, but then immediately stop. There is no error in ISTA. None of the Z11 fuses were blown. Spark plugs, valvetronic motor and coils are new. Any ideas? |

you have compression, if no compression, put some oil into each cylinder and then try to start again.
engine might be flooded or else very common for the VANOS bolts to be broken. |

Pistons and spark plugs were very wet. I took the time to dry them out and put a capful of oil in each cylinder. As a result, the engine started at once. It emitted a very white smoke, but has been stable since then. Thank you very much. And thanks to all of you who gave me advice. Thank you very much. |
