[Breach]

Is there any way at all (obviously outside iDrive) to adjust the distances at which PDC changes the warning beeps? Google hasn't turned out anything conclusive (apart from the default no). My problem is that each and every day I have to navigate a 90 degrees turn in my underground parking designed in the finest traditions of Escher (the turn, the parking is otherwise more or less sanely designed) with distances about 5-10 cms on each side. All the help I get from the PDC is continuous beep which obviously isn't much help, so if there's any way (including going to the dealer if all else fails) to give me +5 cms of tolerance before the dreaded beep of imminent doom, that'd be great... Thanks in advance.
