Yes it does - seems to be about the 100K mark, although my '99 made it to 200K before the gearbox died and that never had the problem - probably because it spent most of its time on the motorway. The fundamental problem is the moving contact which touches the single contact in the silver-coloured section. The points on the contacts are rounded so they move nicely over the stationary bits, but that one has been flattened by riding up on to the contact and off again. The only solution would be to replace the sprung contact, but its not possible to hand-make something like that easily. Not for less than a new switch anyway. Its going to be an option for the future when the new switches are NLA though.

It does - its directly attached to the gear linkage. The switch is rather clever though in that the arrangement of the contacts allows the TCU to know not only which gear is selected, but also which direction the shifter is moving. So, it knows when it was in N and moved towards D, but with the bad contact it moves out of N and then gets an implausible signal - only half the contacts it was expecting, and throws a code.
