Hi,
I just bought recently this Sprinter 906 with engine 651.955 and I tried (almost)everything that I know to repair this error but no success at all. So, I checked all connectors, ground points, and engine wire, I checked the fuse box and relays, I replaced the battery and the battery sensor (located on negative cable at battery connector), the alternator, checked with different software and interfaces and more but nothing make to change the battery voltage17.8-18.0V from ECU in circuit 87, even with the engine off the value is the same. Only change the raw value between 19.5-25.5V depending by the battery condition (flat battery/charged battery/engine on).
The last option at this point is to check the ECU and the map for errors by somebody specialised.
I really appreciate if anybody have experience with this error and can give me some advice.
