Hi guys,

So I've procured replacement canbus gateway as mine (3C0907530C) is known to be susceptible to battery drain with RCD510 head unit which I also got.

But (there is always but) I'm having a hard time re-coding the new one 3C0 907 530Q. My old (current) gateway coding is BFFD9F04C21003 which I think uses 7 bytes code (can't remember but the new one might be 9 or 12 bytes?)

In any case when I connect the VCDS it gives me all errors nothing registered as expected. When I go and select "19 Gateway" and register all components which I have on the car in Long Coding Helper then exit and select "Do it" either nothing happens or I get an error message to choose Y, N or cancel. Y tries to code it but comes with error message, N option I think it says to code 1234/123/12345 or something like that and cancel goes nowhere.

Even tried to enter the old coding value under the "New Coding" field directly it still didn't work.

Have you guys have any suggestions other than to put a can of petrol (or ) to it or to buy a new car?

Cheers
