EPB Retrofit ... the way to Stop & Go

[MT-V6]

I'm eagerly awaiting my module to arrive also

Just to confirm, is this the right connector for it? 3C0 973 763 A

Yes

I guess you are reffing to this?

EPB Retrofit ... the way to Stop & Go

Ladies and gentlemen, let me present you my (world's first?) VW Transporter/Multivan/Caravelle T6 with Electronic Parking Brake :D I just need to complete the wiring of my PARKING BRAKE indicator in INSTRUMENT CLUSTER and AUTO HOLD. The skills of people on this forum never fail to amaze me...

www.t6forum.com

I have used the AUTOHOLD switch and indicating LED for a different purpose.
Soon I will disclose publicly its functionality.

@Robert @dnoermann ,I went the EEPROM route to avoid solid state relay wiring headache, but after enabling (P) symbol and Electronic handbrake in eeprom, I am surprised to see the (!) symbol coming up on dash instead, address 17 and 53 do not have any error anyway.....my eeprom is 24c64,

Did you modify the instrument cluster circuit board as well as editing EEPROM?

 

[siLc]

I removed 1211 resistor to the left of display,then added 2 at the back

Yes, I removed 1211 resistor to the left of display,removed a 3 legged black resistor at the back then added 1101 & 4990 ,according to these photos, I am not sure is I should have left the black 3 leg in place,my pcb looks like this second photo after mod

 

[TheKeymeister]

Was just checking! To me solid state relay wiring is much less of a headache than cluster disassembly and PCB modification but each to their own

Hopefully dnoermann can help you with this

By default the Autohold on T6 ABS module MK100 is disabled in the firmware and therfore it is not available (yet ).

No, the T6 ABS does not support Autohold.
But i am working on that ....

For the ambitious T6/t5 retrofitters.
danman is using a car which does have an ABS that supports Autohold ... probably no T6
For the T6 we first need to patch ABS to support Autohold ....
Already working on it

Just a note for discuss
Found that Audi TT 8S/FV MK100 ABS controller supports Auto-Hold
at Auto Hold Assist MK100 ABS module long coding 8S0 907 379 F (e.g. Audi TT MK3)

Here's how to enable hold assist on a MK100 ABS controller, for example PN 8S0 907 379 in an Audi TT 8S/FV

ABS Module 03 Long Coding
Byte 15: Set bit 3 (Usually 06=>0E)
Byte 16: Set bit 7 (Usually 33=>B3)
Byte 25: Set bit 4 (Usually 60=>70)
Byte 26: Set bit 0 (Usually CC=>CD)

ABS Module 03 Adaptation
Security access: 20103
Adaptation: IDE05263-AUTO HOLD functionality => activated

Note:
You will need to install and wire in the auto hold button and new parking brake switch.


From some research the long coding for this module seems to be made up roughly as follows...
Byte 00: Unknown coding
Byte 01: 0xA9 + 11th VIN digit?
Byte 02: Unknown coding
Byte 03: 0x8D + 12th VIN digit?
Byte 04: Unknown coding
Byte 05: 0x99 + 13th VIN digit?
Byte 06: Unknown coding
Byte 07: 0xA9 + 14th VIN digit?
Byte 08: Unknown coding
Byte 09: 0x91 + 15th VIN digit?
Byte 10: Unknown coding
Byte 11: 0x54 + 16th VIN digit?
Byte 12: Unknown coding
Byte 13: 0x91 + 17th VIN digit?
Byte 14: Unknown coding
Byte 15: Bit 3 - Auto hold assist enable
Byte 16: Bit 7 - Auto hold assist enable
Byte 17: Reverse order of bits in byte 00
Byte 18: Reverse order of bits in byte 02
Byte 19: Reverse order of bits in byte 04
Byte 20: Reverse order of bits in byte 06
Byte 21: Reverse order of bits in byte 08
Byte 22: Reverse order of bits in byte 10
Byte 23: Reverse order of bits in byte 12
Byte 24: Reverse order of bits in byte 14
Byte 25: Reverse order of bits in byte 15
Bit 4 - Auto hold assist enable
Byte 26: Reverse order of bits in byte 16
Bit 0 - Auto hold assist enable

The coding, of course, differs from our 7E0907379P / 7E0907379Q
I hope this info will be somehow useful to impulse this topic
It will be great to find out how to bring those functionality to T6 ABS unit for stop and go with ACC

 

[dnoermann]

Thx, but that CAR Type uses the MK100IPB (IntegratedParkingBreak) Version like in Golf 7 and that one is for MQB Plattform.
Thats incompatible to PQ25 of the T6
