VW Audi Group Electric Park Brake Repair & Upgrade

The electric park brake is a feature that has been rolled out by many vehicle manufacturers in the last few years and VAG (VW, Audi, Skoda and Seat vehicles) are no exception to that.

Although there are several advantages to the electric park brake, these come at a cost – a system made up of ECU’s (fig. 1), buttons (fig. 2) and motors (fig. 3) networked together via a complex electrical architecture which replaces a conventional cable operated handbrake.  The higher end VW and Audi models (Passat & A8) were the first to adopt the new technology, but these earlier systems were however prone to a number of failure modes.

With age, the callipers and motors are generally the first parts to fail, resulting in a park brake that either won’t release or engage, with various warning lights on the dashboard!  Severity and inconvenience of the different failure modes vary, but, for example, a common occurrence is that a vehicle can be made immobile, away from home, requiring specialist knowledge to even get the car onto a trailer for recovery and subsequent repair.  Because of this, it is very important to take action if there are any early signs of EPB malfunction at all – since ultimate failure is almost certain to be at least very inconvenient, expensive and maybe catastrophic.  Servicing these parts without the relevant diagnostic equipment is not a job for a novice – since even changing the brake pads requires the motors to be backed off electronically through the diagnostics port!

Beyond this, our experience has shown that simply replacing the calliper/motor combination is not enough to make a system fully reliable again.  As well as updating the software in the dedicated park brake control unit, various other physical parts of the system should also be changed for newer generation components in order to avoid catastrophic damage to those new callipers and motors that have just cost you hundreds of pounds!  For example, bugs in the earlier software levels can result in scenarios where the park brake motor is backed off too far, leading to motor burn-outs and faulty operation.
