Moin in the round, the following has happened (R172, Bj 2011, 100 Tkm, hand switch, M271); quiet BAB-drive, cruise 120, dry, everything in order, Then suddenly breakdowns Tempomat, ABS, ESP, tyre pressure etc… Car otherwise continued normally, I had never before, regularly waited at MB. Briefly stopped, engine off, waited again, Fehler message remained. Yesterday morning then, when switched on ignition, only again all error messages present, at the first brake then away, but arrived n I did a underwear wash because I wanted to exclude dirt, but didn’t use anything.. Was yesterday at MB, who thought wheel sensor at the front right shows no values. Suggestion to change it. Sounds plausible… My questions to you are now; Is that “normal” that such a sensor fails? Can you fix something like that? Contacts blank, or clean or something like that, or does it have to be new? Is this a wear part? Do you have any other tips? Greeting KK
