NeilMK5 Golf Boot Handle Mod onto MK4 Tailgate - The aRd OEM+ way
I have had numerous emails/ pm asking how to do this modification especially the wiring and fitting of the solenoid to control the latch
I thought its time I write a simple guide. I do not have the time to write a detailed guide.
I hold no responsibility for this modification at all, do it at your risk.
This modification will work like if it was done by VW themselves. I did the original wiring to work with a 3 button keyfob with panic button and switch hidden between the number plate lights back in 2002.
Parts as a guide:
Beetle latch : 1C0 827 511 C 01C
Solenoid Petrol flap: 3B0 959 782
Let begin with the CCM version in your Golf.
Easy way to identify which CCM version you have, split your key in half and the part no on the remote :-
it will begin with HLO 1J0 959 753 and there will be a letter at the end of it. That's the important part
HLO 1J0 959 753 A - CCM - 1J0 959 799 AH - no need to change the CCM - need a custom 3 button keyfob
HLO 1J0 959 753 N - CCM - 1J0 959 799 AH - no need to change the CCM - need a custom 3 button keyfob
HLO 1J0 959 753 AG - CCM - 1C0 959 799B - Golf you must use a Bora CCM part no 1C0 959 799B - can use HLO 1J0 959 753 AH 3 button key fob
HLO 1J0 959 753 AH - CCM - 1C0 959 799B - Golf you must use a Bora CCM part no 1C0 959 799B
HLO IJO 959 753 A - All vw's from 1997 - 2000. HLO 1JO 959 753 N is usable and superceeds the older oval key used previously! (2 button)
HLO 1J0 959 753 AG - vw golf's only 2000-2004. HLO 1JO 959 753 CT now superceeds the older part number hlo 1jo 959 753 AG. (2 button)
HLO 1JO 959 753 AH - vw passat's/bora's generally. HLO IJO 959 753 DA superceeds the older AH. (3 button)
<2001 1J0 959 799AH - No need to replace. I can supply custom 3 button keyfob, but need a little bit of notice and a deposit as well. This only to help forum members, use my own time and need to source the parts
>2001 1C0 959 799B - Need to replace with the Bora version I can supply these , drop me a PM if you need one, only if you're serious. Please don't waste my time and i take a non refundable deposit. I've had to many timewasters and then I'm out of pocket.
The wiring for the 1J0 959 799AH
Need to purchase additional automotive relay, standard pin configuration. Similar VW one is number 53
CCM pin 13 needs to feed to standard automotive relay pin 86
Pin 85 and 87 standard automotive relay needs to fed from CCM pin 22 of 23
Pin 30 standard automotive relay need to feed to the solenoid in the tailgate, solenoid pin 1 and pin 2 of the solenoid is permanent negative (find one in tailgate wiring)
MK5 boot handle is micro switched. Pin 2 of this needs to be connected to permanent negative feed. Pin 1 of handle needs to be fed to CCM pin 21 of 23
The wiring for the 1C0 959 799B CCM
Need to purchase a Bora CCM, worse thing is the Bora ccm shares the same part no has the Golf version. The difference in the internal eeprom code.
There is no need for an additional relay like the 1J0 959 799AH CCM
CCM pin 18 of 23 is fed directly to the solenoid pin 1 and solenoid pin 2 is permanent negative
MK5 boot handle is micro switched. Pin 2 of this needs to be connected to permanent negative feed. Pin 1 of handle needs to be fed to CCM pin 2 of 23
