supreme Posted June 25, 2014 Report Share Posted June 25, 2014 Hi there,I bought a Lupo 3L steering wheel recently, complete and in good condition, but I have a little problem...I've asked my local VW (Paris suburban) to install it in my Lupo GTI but it happens that the horn is not working, and they don't know what explain this and how to solve it.. I'm also wondering if they are really competend at their job tbh.. So does anyone know the problem or have any idea to solve that??Any help would be really appreciated!

Thore J Posted June 25, 2014 Report Share Posted June 25, 2014 I should work.. As I know some guys here in Denmark fitted a GTI steering wheel in their 3Ls... and was no issue about the horn! Quote Link to comment Share on other sites More sharing options...
Rich Posted June 25, 2014 Report Share Posted June 25, 2014 take the cover off the fusebox, when you press it does the relay click ? Quote Link to comment Share on other sites More sharing options...
supreme Posted June 25, 2014 Author Report Share Posted June 25, 2014 Will have a look tomorrow @Rich.I know a few people already made that modification but they may have do it letting aside the horn? The VW mechanician told me about a "Can" cable/connection being different on the two Lupo versions.. Quote Link to comment Share on other sites More sharing options...
Rich Posted June 26, 2014 Report Share Posted June 26, 2014 They're both 'can'.your tech is an idiot, Quote Link to comment Share on other sites More sharing options...
supreme Posted June 26, 2014 Author Report Share Posted June 26, 2014 Haha, that's indeed the feeling he gave me, but as I'm far to be a mechanical expert I couldn't really contradict him..As for the relay, I tried my best but was unable to acces them. Could it be just a relay problem even if the horn works fine with the actual steering wheel..? Quote Link to comment Share on other sites More sharing options...
Rich Posted June 26, 2014 Report Share Posted June 26, 2014 If the relay is clicking then the problem is in the engine bay.If it isn't clicking then the problem is at the wheel.We are starting fresh with diagnosis. Quote Link to comment Share on other sites More sharing options...
supreme Posted June 26, 2014 Author Report Share Posted June 26, 2014 Mmm I see.. that's an interesting trick.Well as I have no idea if I will be able to access the relay I'm kinda stuck there, may try my luck at another VW... dunno.

Rich Posted June 26, 2014 Report Share Posted June 26, 2014 You simply pull the cover off the fusebox and listen for a click when you press it.Hardly rocket science. . . . . Quote Link to comment Share on other sites More sharing options...
supreme Posted June 27, 2014 Author Report Share Posted June 27, 2014 Then using that other trick (get out the fusebox seems to be a total nightmare!) I can definitely tell there no click when pressing the fusebox/relays. That's a first thing good to know. Quote Link to comment Share on other sites More sharing options...
Rich Posted June 27, 2014 Report Share Posted June 27, 2014 Good, then we're onto the wheel.Liable to be the earth through the stalks.Can you get the airbag/wheel off?Inside the wheel there will be a black earth which connects to the airbag Quote Link to comment Share on other sites More sharing options...
supreme Posted June 29, 2014 Author Report Share Posted June 29, 2014 Rich you'll not believe it but I only realized now that my 3L wheel was off and then checking the fusebox seems to have been unnecessary! Hahaha oh damn, should have clarified that...So to be clear, back from VW they put back the classic GTI steering wheel because they didn't succeeded to makes the horn work on the 3L. And here is photos of the 3L as it is now... on the floor... sad...Looks complete to you? Quote Link to comment Share on other sites More sharing options...
Rich Posted June 29, 2014 Report Share Posted June 29, 2014 That looks complete. fit the slip ring and plug the black wire into the tab on the wheel. Quote Link to comment Share on other sites More sharing options...
supreme Posted July 1, 2014 Author Report Share Posted July 1, 2014 Yep already did that, and i guess the VW techinician did too.I think it will be hard for me (us) to find what's wrong without having the wheel on the car now as everything seems right on paper. I thought they may be something I wasn't aware of but apparently no, it should work..Thank you for your help anyway Rich! Will let you know on here if I find the solution.
