What can go wrong

In isolated cases it is possible for vibrations within the vehicle to in turn vibrate the wiring harness connected to the Sensotronic Brake Control unit. This causes the internal contacts within the unit to suffer abrasion and subsequent resistance increase. The resultant affect is that more effort will be required on the brake pedal to stop the vehicle.

The fix

Recall the vehicles that are likely to be affected and mount an additional bracket to the electrical harness to prevent relative movement.

Is a specific car affected? A recall lists models and build dates, not individual vehicles, so these pages cannot tell you whether one car is included. Enter the registration on the DVSA vehicle recall checker on GOV.UK, or give the vehicle identification number (VIN) to the manufacturer or one of its dealers. Buying used? Ask the seller for proof that any recall work was done.
