About 10 years ago, the ABS error “wheel sensor at the rear right” came in. A dear Forist then soldered me the control unit. Since then, I had rest. Now the ABS lamp lights up from time to time. I read the following with Delphi: 312 ABS wheel sensor at the front right – circle faulty 322 ABS wheel sensor at the front right – extrapolation counter 443 pump motor – electrical or mechanical error Then I reset the errors and drove another 10 minutes. The re-reading brought the error 312 (see above). What do you mean, is the controller again the first suspect in this error pattern?
