Would like rear hatch lock to work with door locks

I just obtained a 05 Golf TDI and would like the rear hatch lock to work with the door lock and unlock. The car is garaged and almost never locked. The remote is normally in the ignition, since I hate carrying several keys and remotes. I have tried to unlock the rear hatch when I get out of the car, but after a few minutes it locks again. Does anyone know now I can link the rear hatch lock to the door locks so it is unlocked when the doors are unlock and locked when the doors are locked?



When I open the garage to go somewhere, I many times have items that I want to put in the rear, but since rear is locked, I must put things down, and open the drivers door to open the rear hatch. Just an irritant I would like to get rid of.



Side note: My key will not open the rear hatch. If I have this repaired, would it have any effect?

If the car is garaged why not just open the lid.
The lights should go out in several minutes.

I remember reading that someone figured out how to do this. It required wiring modifications IIRC. If you search you might find the thread.

You might be thinking of the "Pencilneck mod"... one diode after removing the driver's side door card:

Works great for Wagons... should work for Golf hatches as well?

I have been meaning to do this on my Golf. I think this http://forums.tdiclub.com/showthread.php?t=333745 is the thread you might be looking for.

If you happen to know someone with VDS-pro, this can easily be done by recoding the ccm. There is no need to mess with any wiring, just hook up the cable and change a few byte values. I have VDS-pro and this took just a few minutes to do on my 04 R32.

Thanks VE1.9. I have VDS-Pro and recoded my 03 Jetta Wagon CCM to have the hatch function with the other doors, but for some reason thought it did not work the same on the Golf. Could you point me in the right direction for the Golf as it has been quite awhile since I did this on my Jetta.

Check out this thread. Post 771 should have just what you need.

Success!

As per VE1.9's suggestion and the provided link I used VDS Pro and now have the locking and unlocking of the hatch on my 2003 Golf working like one of the doors.

Thanks!

Just a bit more info to hopefully help out the next person doing this with VDS Pro.

The original coding for my 2003 Golf (CCM 1C0959799C) at addresses 04352, 04353, and 04354 was 136 (10001000). I had changed several things in VCDS so yours is likely different.

Recoding mine to 24 (00011000) retained all that I had done in VCDS, while making the hatch act like a door with respect to locking/unlocking

So it seems like you want the 4th position to be on (set to 1) and probably the first to be off (set to 0, but I'm not sure what this controls so maybe on is okay?).

Basically, use VDS Pro to read what the above 3 addresses are currently set to, figure out what that is in binary and then change that binary to have the first position as 0 and the 4th position as a 1 and recode with the decimal for that number.

Actually, it's 40.
The 3 zero's from right to left would be 2 4 and 8.
the next 2 would be 16 and 32 which added together is 40.
