Can you check the horn feed from the mfsw with a multimeter?

How do I do that please? Also all worked fine after mfsw fitting. And on my mk5 tdi before hand, got about 3 modules spare and 5 clock rings all ending different letters.

Have you got a diagram showing connections?

No mate vw really made sure we need there help with mk6 onwards, thing I thought might be was wires under airbag not going to correct places, got old vagcom lead I tend to use, just not sure I've located correct relay was told 646 I have x2 changed both, got a diagram/fyse layout pics on phone if woukd like a look at that, cheers 4 help m8

Bit it did work, so the connections must be right. There must be a traceable fault. Could there be a loose connection or trapped wire? If you could do some voltage/continuity tests it could be useful

No idea on the vagcom side of things sorry. Is there continuity between the horn output from the mfsw and the relay?

Mfsw all works fine, rest was all working fine for mths then horn stopped, veven replaced old sw and cr and module still no horn.

Theres a fault somewhere and I can't see how you're going to trace it without some good old fashioned continuity testing.

OK m8 I'll try find video on YouTube on how to do it, but got meter and the light one aswell with just the ground clamp on it
