Thanks for the reply, i found the part numbers for the 312 carriers, if anyone wonders they are 8V0 615 125A and 8V0 615 126A.
As for the ABS coding, this is the first I'm hearing about this. Is is something i can do alone or does a delalership have to do it?
A dealer "cant" do it. It's easy enough to do with VCDS etc if you take your time. It's important you do this for correct operation of ABS/TCS/ESC
Byte 4 should be either hex 30, 31 or 34 depending on the PR code of the brakes you've installed. Remember it starts at byte 0, so it's actually the 5th byte.
Looking at the parts diagram it looks like the only 312mm front brake configuration on the Leon is 1ZA
30 being 1ZA (312X25MM)
This is also mirrored in Byte 17. (Mirror byte 4 binary in byte 17 binary).
Example of how mirroring works
lets say that Byte 0 is
0E
Take the Binary value of
0E (Binary
00001110 in LCODE)
and read it backwards to get the mirror of the byte
Which would make Byte 15 be
70 (Binary
01110000 in LCODE)
You have to change both bytes together otherwise you won't be able to save the changes.
