MFSW upgrade - horn constantly on
« on: March 27, 2019, 09:32:38 PM »
Car is an MK5 56 R32.

I had a non MFSW. I have upgraded to:

the CH module - 1K0953549 CH
a Meyle cruise control stalk
the wiring harness to include the SW controls - 5K0971584C
cut away the SW foam and added in the MK5 controls from a Passat (they're the same as the Golf ones)

I done the CC first and it worked perfect. I coded it using VCDS. At first the horn wouldn't work so I changed something (I think the module in VCDS) and it worked again.

Then I done the SWC and again, this worked first time. All the buttons work.

I had a couple of faults. 1 airbag would clear on VCDS but then come straight back on. 2 as soon as I turned the SW, the horn would continuously sound. No wires are stuck or broken. I have removed the horn fuse to stop the beeping and this has cleared the airbag fault.

Any ideas on how to get rid of the horn noise?

If anyone is interested, I have some pictures from the upgrade.

Thanks.

Are you sure the wiring harness is the correct one? I think the part number should start with 1k0.

This is the one I bought. I done a bit of research and I'm 99% sure it's right. It's exactly the same as what I had but with the extra bit of the SW controls (black connector).  It's a single igniter (same as mine). Everything works on it but the horn is constantly on.

Update and a fix - I needed the 1K0 harness. Anyone with the same problems, this is what it is. Both harnesses look the same. Phew!
