YesI'm eagerly awaiting my module to arrive also
Just to confirm, is this the right connector for it? 3C0 973 763 A
@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,I guess you are reffing to this?
I have used the AUTOHOLD switch and indicating LED for a different purpose.
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
Soon I will disclose publicly its functionality.

Did you modify the instrument cluster circuit board as well as editing EEPROM?
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
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).
For the ambitious T6/t5 retrofitters.
danman is using a car which does have an ABS that supports Autohold ...
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)
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

After a short break (for just two years
) because of the frustration with this communication problem with my 56D I'm back, ending this break by trying to find a solution. What shall I say - it was #19. After replacing the 7N0 Getway everyting is fine and communication is stable.In this context realized, that I've attached an empty EEPROM file. For those who will find this thread and are in search of correct data, I've now attached the correct one. Again rename .csv to .bin.
I'll try to document my journey on my way to retrofit EPB in my VW Eos 2015.
Best regards

Hi friend,I have a EPB module 3AA from Sharan,if put your EEPROM file from 56D it's possible working on mk60ec1 abs?thanks
Ok,but it's from sharan the module,I remove all parts for EPB and this module from a Sharan demolished
And yet another periodic inspection carried out on the 13/09/2024.The truth about EPB revealed itself.
My Caravelle, Multivan(you name it
It was a pass on the first attempt so I am very happy and proud of my work.
Again credit to @dnoermann for the inspiration.
Below is a comparison of my test results.
Manual/Mechanical Parking Brake(test conducted on 14/09/2020)
View attachment 176082
Electronic Parking Brake (test conducted on 14/10/2022)
View attachment 176083
Parking Brake performance has risen from 21% to 26%.
Rear axle brake effort also went up on both sides
My EPB has be verified again to be functional up to the required standard.
Time to start Robert's Retrofits and provide this as a service to the general public
Interesting. I'm surprised they don't do this already.
I drove a T6.1 with DSG and ACC around May last year - it definitely did Follow To Stop and then automatically started again.
I found that I had to follow the instructions on the dash, which was when coming to a stop brake as instructed and then once the traffic had moved on I could release the brake and the van would start again. I don't remember if there was an auto hold function but being a T6.1 it had a mechanical handbrake.

5N0 uses different switches and capacitors instead of diodes.
I have explained the details below.
My play with EPB switches has come to the successful end
View attachment 109573View attachment 109574
Unfortunately, as posted here, switch 5N0927225B is not direct replacement for 56D927225.
Unit 5N0927225B uses 6 pins for actual EPB switch with 2 internal capacitors and unit 56D927225 uses 4 pins with 4 internal diodes.
Additionally micro switches are also different, first one has 2 x (separate N/O contacts & separate N/C contacts) against second one with 2 x ( double N/O, C, N/C).
Taking into account the size of internal PCB and SMD components I decided to transfer 2 micro switches from 56D927225 to 5N0927225B.
Illumination and all indicators are used directly from 5N0 PCB with 56D micro switches wired externally to the 56D PCB.
What's worth to mention is that unit 5N0927225B is identical physically and electronically to 5N0927225A.
Alternative method and probably much more straightforward would be to use 7N0927225B unit.
It uses 16 pin plug (part number 1K0927928).
Pins 1, 2, 3 & 4 correspond directly to the wiring of 56D927225 unit.
Pin 5(+) & 6(-) are for illumination.
Pin 9(+) & 10(-) are for EPB ON indicator.
Pin 12(-) & 13(+ in) are for Auto Hold indicator.
Pin 13(+ in) & 14(+ out) are for Auto Hold switch.
Remaining 5 pins are not in use.

Summarising all 3 (16 pin) units mentioned above 5N0927225A, 5N0927225B & 7N0927225B look identical externally
but only 7N0927225B has the same electronic internals as 56D927225

7N0927225B is much easier approach and you should be able to find inexpensive second hand unit somewhere online.
Follow To Stop description sounds correct but automatic resume of ACC does not.
By putting your foot on the brake pedal the Adaptive Cruise Control gets cancelled. In order to re-engage the ACC functionality, the MFSW button (RES or SET) needs to be pressed again.
No not at all - and I would agree that braking would cancel ACC, but I put it to the test on the M25 on the way to Campervan Campout to see how brave I would be.
I even recorded an audio commentary at the time for use in a programme, but I'm pretty sure I deleted it (it wasn't very good).
I had ACC set to 60, the traffic was slowing and the van slowed down to a stop behind the traffic that had stopped. I was then instructed, via the DIS/MFD, to apply the brake but I don't remember the next bit (i.e., whether I released the brake before the traffic moved off or I waited until it did). Once the traffic moved, I didn't need to apply the throttle to get the van to start again. I am certain of that much.
It was a 7 speed DSG Highline spec converted panel van from a hire fleet.
