ABS issue

NickIOW · 06-04-2023, 01:21 AM

Hi all,

Looking for a bit of advice for my e91 335i lci.

Currently experiencing a issue with the ABS.
Every now and then, normally at the start of a drive, the ABS, DTC and parking brake light all come on for up to 5 mins then go off and everything is fine.

Also the ABS has started engaging from below about 15mph in dry conditions under light braking.

Have had a look in some other forums and looks like the wheel speed sensor could be the culprit.

Can anyone confirm this is the likely problem? Also what's the best way to diagnose which sensor is at fault?

Thanks,
Nick

You’ll want to get a bmw-capable scan tool. Without that, it’s just a guess. The DTCs will tell you the problem.
