Quick one...my 2008 E91 is saying it needs new front pads. I am a competent spannerer...is this a DIY job? I have no problems with the mechanical aspect, however will the computer need resetting in some way to clear the warnings on the iDrive? I have a basic OBD2 generic code reader/clearer however I don't know if the BMW needs specific equipment here. I was told even a battery swap needs to be done by a dealer for this reason...

Thanks in advance...

Should be straightforward as long as you fit a new wear sensor - IIRC the pad indicator can be reset from iDrive.

As for batteries, it depends. If you fit an identical replacement you're fine - if you change the capacity then it has to be registered so the correct charging profile is used.

You can reset the pad sensor on the dash by pushing buttons (with a new sensor), unless warning has gone red. Then you need diagnosis software to reset.

While respecting you're comment. This is wrong. Just takes multiple attempts.

Changing the pads is easy as already said. Before doing that I would check that new pads are really needed because those sensors can be too careful. I have 8mm to 9mm on the pads on my F30 but the service indicator shows that a change is due in 4k miles, they will last much longer than that!

Fair enough, you learn something new every day! I just get the laptop out as it works first time.
