Hi,

So a customer wanted to have rear door handles with keyless doorhandles. He ordered the parts, but the wiring was different. After doing some research i saw that he had the pre facelift golf ELV and KESSY module (5Q0 905 561 + 5Q0 959 435).

The next thing we tried was to swap out for newer ones. According to various scans, the best combo would be 3Q0 959 435 N + 2Q0 905 561 A.

First we tried with used parts. This didn’t work. So naturally i thought i needed new parts. I ordered new parts, but still same issue;

FAZ1738E

Slave-position bereits mit anderem steuergerat belegt.

I cant adapt elv to car. And i never saw this error before.

Anyone did this upgrade already? Is it even doable? If yes, what is the workaround?

car is factory key less go ?

Yes

replace kessy module who support 4 door handle, then load proper dataset , and re-leran keys
no need to touch ELV
