406 Hdi auto lights

Post by PeterN » Sat Oct 14, 2017 12:58 pm

My auto lights have suddenly stopped working with the result that i find myself driving in adverse conditions with no lights on. :shock: If you press the button on the stalk it comes up 'auto lights active' but they aren't, the auto wipe also seems to have packed up. Any suggestions?

Thanks Peter

Friday 13th?
Early Haloween?

Suspect your BSI has spontaneously unconfigured some options for you.

Try a BSI reset or PP2K

I was going to try a reset but didn't want to have to set the clock again. :frown: I will try it, thanks.

Alternatively, both are controlled by the same sensor, the one at the top of the windscreen...

Thanks that had occurred to me, could be a supply failure, I will try the course of least resistance first and do a reset.

I seem to remember the wipers will revert to a basic intermittent program if the sensor goes wrong.

Yes, they work OK on manual but just not on auto.

I accidentally 'unconfigured' auto wipers just after getting my current 406 while enabling the auto rear wiper.
The front wipers then didn't work at all in the intermittent/auto position.
IIRC you can have auto, normal intermittent or nothing at all.
