Mercedes GLE ABS Fault Lateral Acceleration Sensor

My 2018 Mercedes GLE hybrid is throwing some nasty codes The ABS lamp is constantly lit, and the whole ABS system seems to be offline A diagnostic scan revealed a fault with the lateral acceleration sensor Has anyone experienced this I suspect a defective control unit is the culprit I’m looking at around 1000€ for the repair Super frustrating, especially since it impacts traction control and vehicle stability

A 2018 Mercedes GLE hybrid is experiencing ABS system failure, indicated by a constant ABS lamp and a diagnostic code pointing to a lateral acceleration sensor fault. The suspected cause is a defective electronic control unit (ECU), but it is advised to first check the wiring and connections to the sensor for any loose or corroded connections. If these are not the issue, replacing the control unit may resolve the problem, and consulting a workshop for precise diagnostics is recommended.

Did this summary help you solve your problem?

Yep, sounds familiar I had a similar issue with my GLE Same symptoms: ABS light, system failure, and a lateral acceleration sensor fault code If I remember correctly, the electronic stability program (ESP) was also affected, right The root cause might be a faulty electronic control unit (ECU) Before you drop a grand, double-check the wiring and connections to the sensor itself A loose or corroded connection can sometimes mimic a sensor failure Have you checked that already

I did inspect the wiring harness visually, but didn't do any in-depth probing Where exactly should I be focusing my attention Any specific connectors or sections of the harness known to cause problems Also, did replacing the control unit completely resolve your issue

Okay, so on mine, the connector at the sensor itself was the problem It looked fine at first glance, but I unplugged it, cleaned the pins, and applied some dielectric grease That didn't fix it though Replacing the control unit did solve the problem completely But honestly, unless you have access to advanced diagnostic tools, you're probably better off letting a workshop handle it They can pinpoint the exact cause, whether it's the sensor, wiring, or the control unit itself Saves you time and potentially avoids further damage

Thanks, that's super helpful I appreciate the insight Sounds like I'm heading to the workshop At least I have a better idea of what to expect now I'll post an outcome after the repair is complete
