Mercedes SL-Class 2014: ABS warning lights and speedometer warning light illuminated - possible defect in the wheel speed sensor

Warning light in the speedometer of the vehicle

Hey guys, I have a problem with my 2014 Mercedes SL-Class, diesel, with around 86300 km on it. The ABS warning light and the warning light in the speedometer have recently come on and the ABS system is not working. The fault memory also says what's wrong. I suspect that the wheel speed sensor (ABS sensor) is the problem. Have any of you had similar problems and perhaps had experiences with workshop visits that you could share? I'm a bit unsure at the moment as I didn't have a good experience with my garage last time. Thanks in advance!

Hey, I had a similar problem with my 2011 Mercedes E-Class. The ABS warning light also came on constantly. In my case, however, it wasn't the wheel speed sensor that was faulty, but the ABS control unit. However, it wasn't just a simple repair, it had to be completely replaced. So this is no small problem. I had to leave my car in the workshop for a while. The next time, I already knew what error the indicator light was showing and was able to fix the problem without much delay. I hope I was able to help you with this. Please keep us up to date!

Hey, thanks for the tip! I hadn't even considered that it could also be the ABS control unit. It really doesn't seem to be a small thing. Do you remember how expensive the whole thing was for you? And have you experienced anything similar since then? I hope not. Thanks again for your help!

Hey, no problem! It actually cost me €1000 to repair the ABS control unit. That was quite a lot of money, but since then the car has been running like clockwork again. And since the visit to the workshop, the wheel speed sensor (ABS sensor) has also been fixed. Since then, there have been no more problems in this direction. So I would advise you to have it checked - it's better to spend more money once than to end up paying twice because something else breaks. Keep me posted on how things go for you!

Hey, thanks for your help and advice! 1000 € is a lot, but if it solves my problem and everything runs smoothly again afterwards, it's worth it. I'll take your advice and make an appointment at the garage to have it checked. I hope I have the same luck as you and don't have any more problems after the repair. I'll let you know as soon as I have any news. Thanks again!

Hey there! Sorry to hear about your ABS issues. I haven't had that problem, but I've heard wheel speed sensors can often be the culprit. Have you checked any other garages nearby that might have better reviews?

Before you take your car to the garage, you might want to check the ABS fuse. Sometimes, a blown fuse can cause the ABS light to come on. If the fuse is fine, then it's best to take your car to a professional. Remember, ABS is a crucial safety feature, so it's important to get it checked out as soon as possible.

Sure, I can clarify. The ABS (Anti-lock Braking System) has a dedicated fuse in the fuse box. If this fuse is blown, it could cause the ABS warning light to come on. You can check this fuse yourself. It's usually located in the engine compartment or under the dashboard. If the fuse is fine, then it's likely a more complex issue and you should take your car to a professional. Please let us know if you have any other questions.
