Thanks for your reply ALK.AMG. I will replace mine when I get them. I have error codes on both left and right side front ABS sensors.I have tried this when the error was intermittent. I removed the sensor, cleaned it, i have also cleaned the sensor hole with some cotton buds (not sure if this is recommended / safe) but there was a lot of dirt inside, then compressed air. but when I put back the sensor, I’m still having the same problem.
