Had a momentary occurrence of this error message (it stayed on for some time), but no further fault indication and park brake seemed to work throughout without an issue (set and release were both fine, tested it and could not roll the car with the park brake set).

Clearly - I got the Friday car (with all the issues I've had!) but, has anyone else had this before?

I’ve had various error messages come up, in fact mid week I had an auto hold error but I don‘t believe this is because of the car more me trying to do things whilst the head unit is booting. There are definite software glitches from time to time, I’ve even had a recuperation one pop up when I was miles from home, mild panic followed by a turn off, turn on and all good to go. Haven’t seen it since...........probably jinked it now!

So, I wanted to round up the conclusion to this.

The park brake fault was caused by a defective switch. More specifically the switch LED was intermittent (the one that indicates that the brake is on) and if the car's ECU notices this it flags up a fault. Apparently this is a common problem. It doesn't stop the park brake from working though.

I replaced the switch - cost about £18 and took about an hour. You have to remove the centre console which is a bit of a job.

Interestingly enough I took the old switch apart recently to investigate why the switch had failed and to my surprise I found evidence of water damage on a pair of resistors that feed that indicator LED. It looks like it may have been caused by a spilled drink or something of that sort, I know I have never spilled one so must put it down to the prior owner of my car.

Something to watch out for. If you do spill anything on a switch like this, then clean it and dry it immediately.
