Windscreen wipers activating the brakes in your BMW?

It sounds odd, mainly because it is odd. For the team at ACTRONICS, it often starts with a call mentioning something strange. Yet, we're increasingly hearing of this troublesome phenomenon. As soon as the windscreen wipers are activated, the car suddenly starts to brake whilst driving! 

It's a clever system that BMW have developed, designed to ensure that the brakes are free from water in wet conditions like on the motorway. Although this only makes a fraction of a millimetre difference, it ensures that the car can stop efficiently and safely. 

However, if something does fail, the system not only prepares the brakes but also intervenes immediately. This can lead to dangerous situations that some BMW drivers may have already experienced. 

Which BMW models does this fault impact?

The solution: Have the ABS unit remanufactured

This frustrating problem is caused by a hydraulic fault lying deep within the ABS unit. The ATE MK100 that BMW has used since 2015 requires remanufacturing to solve the issue. 

Remanufacturing is not only sustainable, but also a cost-effective alternative to new replacements. At ACTRONICS, we're well aware of this problem and can repair it quickly with our Hydrotronic solution so that the ABS is fully functional once again. If our final tests show that everything is back in working order, we will return the remanufactured part. It's important when replacing the ABS unit to refresh the brake fluid.
