Hi.
Hawe Polo 2009 with fitted used ABS PUMP:
OLD\DAMAGED 6R0907379 AB
USED\WORKING 6R0907379 S
Working coding from old one:
200200E3007200B2042900EB00D600000000
Used actualy fited:
000000000000000000000000000000000000
This codind dont match to new fitted pump.
With new pump hawe faults:
03190 - incorrect vechicle
01042 - not coded
VIN: WVWZZZ6RZAY050495
I tried to calc coding from thi:
Code:
We can use this information, together with my description, to determine the correct coding for our own Polo 1.6 TDI.
Byte 0:
HEX - Chassis type
10 - Ibiza Hatch and ST
20 - Polo hatchback
As you can see, there might be some options for Fabia hatch and station, Audi A1, etc. Therefore it's always good to google scans of similar cars to your own.
Byte 1:
HEX - Chassis type
02 - Polo and Ibiza
Byte 2:
HEX - Brake diameter
24 - Front 256mm disc - rear 200mm drums
28 - Front 256mm disc - rear 230mm disc
44 - Front 288mm disc - rear 200mm drums
48 - Front 288mm disc - rear 230mm disc
Byte 3:
HEX - Chassis type
DB - Ibiza
E3 - Polo
Byte 4:
HEX - Transmission type
01 - Manual
Byte 5:
HEX 6D + VIN digit #13
Byte 6:
HEX 00
Byte 7:
HEX B2 + VIN digit #14
Byte 8:
HEX - Chassis type
08 - Ibiza Hatch and ST
04 - Polo hatchback
Byte 9:
HEX 25 + VIN digit + 15
Byte 10:
Inverse of byte 2
You'll convert the HEX value to binary, i.e. HEX 21 = BIN 00100001. Then you invert the binary value, so 00100001 becomes 10000100. Finally you convert 10000100 to HEX, making 84.
Byte 11:
HEX E2 + VIN digit # 16
Byte 12:
Inverse of byte 4 (see byte 10)
Byte 13:
HEX D1 + VIN digit # 17
Byte 14:
Inverse of byte 6 (see byte 8 for description)
Byte 15:
bit 1: TDI engine installed
Byte 16:
bit 1 = TPMS active
Byte 17:
HEX 00
This calc its match to old coding (VIN)
But fitted abs says coding wrong same when i change something in old and try to code - only original coding accept.
