PDC range adjust

[oztme]

Hi Chaps,

The Parking distance thingy in my 05 X5 3.0d emits a solid beep when objects are 30cm away or closer. This isn't useful to me. I need to get within 10cm of things. Has anyone seen any hacks that allow the adjustment of the range? I've got one of Rolf's cables on the way, but I doubt that will help.

Failing that, is there any way to set the PDC's so they don't automatically come on when I put the car in reverse? I'd still like to be able to turn them on, but they are a pain in the butt when I am maneuvering in small spaces (5 point turn to get into my garage!)..

Sorry if this is a FAQ. DId a search and couldn't find anything..

Cheers
Scott.
