My auto hold feature has never worked correctly since I got the car. Nearly 2 years ago. It's being back at the dealers endless times for them to fix it. They are aware of some low level error codes that have being logged due to auto hold not working correctly but even after 2 years don't know how to fix the issue.

My problem is simply that once auto hold is switched on and the car is being held by autohold. It will randomly switch itself off and default back to regular park mode without me touching anything or moving off the seat (safety feature).

It's annoying because sometimes you don't realize and apply the gas to move off and of course you can't because auto hold is now off and the normal park break is applied.

The dealer raised a puma case and got the regional BMW rep to look at it but they don't seem to care about it. Pretty lame really.
