You could always go half way with the 324mm as fitted to the 530d (and others)
They are a LOT cheaper than the 348mm ones, and probably more widely available too.

My question is - my last set of discs weren't changed till 73,000 miles and I know they have never been changed previously. So what happens to the service indicator as it approached 25,000 miles - will it need another reset even if the pads are no where near requiring changing ?
Please advise.

The wear indicator is specifically for pads only - the theory is that they wear out faster than the discs, plus if you're changing the pads, it is only a couple of second's job to check the thickness of the discs.
So, if you are concerned about your discs, you have to take the wheel off and get a caliper/micrometer on the disc to check it.
Mine were below the limit at 45k, so your discs at 73k were probably well shot. Also bear in mind that my car is a Manual, so it is less hard on brakes than an Auto because of engine braking. Perhaps the first owner was over heavy on the brakes, who knows?

The pads were changed exactly when the I-drive indicated, in fact both the pads and discs were inspected by the main dealer only a couple months earlier, and they confirmed at that point that neither were due yet for the change.
So actually the previous owner was probably pretty easy on the brakes !
Regardless of the above, I would expect my brake pads to last longer than just 25k miles !
Oh.........and mine's a manual too.
