Thanks Justin,


I just read further through the threads and realised that 'rocket rod' had tested a little further and I can concur.


Neutral leaves the car rolling ... that I can understand .... haven't tried the Door Opened thing yet ..... Turning off in D selects P but definitely does not apply the EPB. That I cannot explain.

I do have a theory as to why the 8-speed do not use the EPB automatically - the design of the Park in the select-by-wire boxes is a cylinder through a disc - this design would be able to endure much more stress than the traditional "pawl" of the cable operated park. I read somewhere that BMW(I think??) don't have a park brake as such anymore, and just use the park function of the auto transmission, as it can be in gear and still activate the park cylinder due to it just being another solenoid to activate.

That makes sense...

As for even attempting to use just neutral and the EPB (more in the 6 speed), in neutral the vehicle doesn't shut down - it keeps systems alive...

I was more asking from a vehicle-secured-against-rolling-away view point but yes, that is a good reason to put it in park

Cheers

When I was checking out a disco purchase i spoke with the Guy at house of Rover in Brisbane and he said that cars that don't release the EPB manually and use the auto release function exhibit a lot more wear than those that choose to release it manually. Its not the first time I have heard of this, our Pug 508 had the same feature and the dealer also warned us about using the auto-release feature. Sadly he told us that after we had to replace he pads AND ROTORS at 30,000km
