Alarm and regular horn has not been working. Checked fuses - all good. Been studying fsm wiring. scaned codes are; 01134 alarm horn h12; 03266 Control circuit for signal horn; 01259 fuel pump relay J17. Switched 646 relay with the other 646 relay (no change) Traced j17 and I think it is the 646 relay but have to study it more. If anyone has ideas would appreciate.

Thank you

Can offer only this: Met a couple with a VW and horns wouldn't blow. They tos ok it to the local dealer who found it need only two new horns. They ordered the horns and owners had to bring it back to have them installed. A day or so later. I don't think I've ever had to simply replace a horn. Still, I saw this live, and it was a VW. SO...Please make sure Horn(s) good before you chase other gremlins.

Thanks for your reply,
Horns work applied 12v to disconnected horns and they worked might be a relay

Yes, horn relay would be the next thing to check. Swap it with any other same part number relay for a trial.
