I was wondering where the alarm horn is located in my Octy II and how easy it would be to get it replaced. The alarm is not working, I'm getting the following fault code:

Don't know if you have sorted this, but H12 is behind the front right wheelhouse liner. It has a non replaceable battery inside. I would be tempted to look inside to see what sort of battery is fitted. I could send some pictures if you email [email protected]
