Servus! I had the following problem today: -when starting the moose only reluctantly jumped on (1.5 hours before I stopped it after 5 km drive; no problems at morning start) -yellow triangle started, ABS/brake light went on, message: ABS/slip protection maintenance required – after engine start again the error indicators remained, after a few meters drive blocked (at least!) the left rear wheel; the moose did not come from the spot – the moose slowly started driving, after inserting of the reverse gear (20cm “drive): no more blocking – after another engine start: slip protection temporarily off I did earlier “Vadis/Vida” for “arms” (thank you, Esker ;-)) : DTCS in Vehicle BCM DTC SET SET SET SRS READY ECM READY AUM READY CEM DTC SET DIM READY DDM CHECKING CCM CHECKING PDM DTC SET PSM DTC SET REM CHECKING SWM READY PHM DTC SET UEM CHECKING There I stand now, I’m poor Thor & as smart as before; well, I can say that now, since I am here http://www .motor-talk.de/forum/bordcomputer-selftest-t1808068.html read what didn’t really get me anywhere… Be driving tomorrow (in the hope that I “drankommen” before 11:11h) I had a little hope that the battery was just “going” (though it didn’t change until November, but doesn’t have to mean anything). But the blocked rear wheel speaks against the battery theory. Well, someone has a spontaneous idea? How about jamming the battery, or is the idea not so good, since it may then not be able to read the errors anymore? Questions about questions… Greeting weflydus
