Saturday my DZM went still impeccable, now since this morning no more. Had on Saturday night a powerful storm with torrential rain, which lasted about 1 hour. Have the assumption that maybe somewhere water may have penetrated into a plug, but do not know if the DZM in the engine room has such a, and if so, where I can find it. Has powerful rained, my li. headlight also got very damp from the inside. Therefore the assumption that my problem with wetness was u could have done so, as my “Essi” parked outdoors. I checked fuses and relays for fixed seats and defects, everything is okay. Otherwise, the electrical system and all displays work perfectly, except for the DZM. I was no longer dangerous since Saturday noon, the problem only found this morning, when I started the engine.
