I've a Mk4 Titanium X Mondeo with the Convers+ system.

If the headlights are on, after about 20 minutes or so it'll report that the lights aren't working, however all the lights are working just fine.

I've checked connections and even replaced the bulbs anyway but it makes no difference.

I put a scanner on the car to see if there was a duff module or something but it was clear.

Whilst it arguably doesn't matter it affects my OCD so would like to know if there is a module or voltage sensor or something that health checks the bulbs that's faulty, there have been a few other electrical gremlins on the car (ACC module was poorly, electric seats don't work) so wonder if this is going to require a similar fix.

Any advice would be appreciated.
