Electronic Parking Brake Failure

I had the car reprogrammed at an indi. My parking brake continued to work but I had the bong and the warning light. I suspected a weak battery as it is the original but the indi tested it and said it was fine. After reprogramming its been fine since.

So, the fault doesn't always mean the parking brake has failed, seems it can lock on, can refuse to lock or just produce a warning but continue to work fine! The battery isn't always the issue. :o , analyse that! :D

I agree with you regarding the issue that its not always the battery's fault! In my case I think it is. The ebrake does not work when I park but if I am moving and push it up, it does work and the car immediately stops. So Sammyz, you too can confirm that the only software upgrade that I can do is doing it at a bmw dealer shop. Correct?

I had the problem except the brake wouldn't go on . BMW sent out a lo loader and took it to the dealership where I was told it was " reset " . So far so good but I'm always wary .

It seems a lot of bmw z4 owners have had this experience...its a shame though, I dont like the idea of an ebrake system, the car could be parked and off it goes on its own!!! How much roughly do they make you pay for a software ugprade?

Yes, you've got to get the software updated by either BMW dealer or a good indi. I was charged £120 I think as they 'investigated' fault and checked battery.

Well my colleague, has I suspected traded in the car, so I will never know the reason.
I think if I have to go to BMW to get this fix, I would push for free or a visit to trading standards.
To me it's safety critical item. Why should reprogramming fix the problem. There must be a problem with the program or some interference from somewhere else.

So a little update...I went to two different mechanics and none of them has got the tools to make a software upgrade. The perks of living in such a small island!!! At the moment I am stuck. Does anybody know if there exists some kind of computer I can buy and make the software upgrade myself???

Not heard of anyone doing the upgrade themselves, can't you get to a BMW dealership?

Hi Sammy, here in Gozo there are dealers that sell bmw cars but they dont even know what a software upgrade is...I have to travel by ferry to Malta, i guess this is my only option here. In Malta there is one agent for bmw cars, just one.

Slightly off topic but I love Malta :thumbsup: , never been to Gozo though but I would love to visit next time I'm in Malta. I visited most of the ancient temple sites in Malta and would like to see the ones on Gozo.

Looks like a trip to Valetta for you then is the only option.
