If there is so much difference with the pad wear, do you think that you could get VWR or JKM to alter the brake bias to give more bite at the rear?

....Is this done via software? If so, then Keith at JKM would be best to do it.

It's something T-T DEMANDED should be done, but as usual when asked to explain how you do it, he couldn't/wouldn't answer. I dont know anyone who knows anything about it or its parameters. I'm guessing it's a dealer version of VCDS job?
Worth finding out though.

I'll have a word with both my friendly VW dealer when I see them on Tuesday and with my mate Dan (ex VW techie) who is now a Revo agent and knows about software. I'm pretty sure it's something that a VW dealer will not be allowed to change from oem and can appreciate why.
Dear old T_T, eh? :laugh: Bless him! He and I have some wonderful exchanges but have met lots of times and it's never a problem.

Bonjour....
Only soft coding available vis a vis brake wise is to tell the ABS what size wheels you're running. Its nothing to do with braking per se, its just so that it can intervene appropiately and "release" the disc properly
Imagine your brake disc clamped by your pads is a rusty bolt, you can either use a 6" ratchet (15" wheels) or a 24" breaker bar (18's) to turn it 18s will continue to turn your wheel where 15's would have locked them up for a given clamping force by the pads .
Its not about the braking systems ability to lock the wheels i.e.2/4/6/8 pot and big discs against 288's
I appreciate its all supposed to be the same rolling circle but invariably its not and I think there is soft coding to trim the MPH reading for different alloys as well
PS numbers totally random to demo the point

....Interesting!
So, for example, my GTI left Wolfsburg with Monza 17's and was therefore soft-coded accordingly. When I swopped to Monza 18's, although it was a factory option, my existing coding thinks I'm still running 17's.
Would the coding also take a weight of the wheel into account? - Surely that would be ignored as such and reacted to smartly according to lack of grip etc regardless of how it was caused.

Maybe start a thread in the VDCs section - somebody somewhere has played with it probably with some success
