Hello, I have for some time the following problem with my 313 Sprinter BJ. 06/2000 undzwar a while ago sporadically the abs and asr started to light up again on Erlisch after. Since the beginning of the week they light up now permanently. I then had the brake light switch replaced but the problem persists, then had the error read out with a known and the error is motor or relay pump faulty ! The error also comes after the delete again. that a mistake in the ABS control unit or at the hydroblock itself ? Cable break I also checked but everything ok.
