Thanks trundlenut I'll have to get it checked.

Octavia vRS? I didn't think they were equipped with light sensors in the first place.

 

The auto-dim mirror is a different sensor.

Good point, I just assumed it had the R/L sensor fitted.

But don't the wipers use a light one.

So you definitely have the sensor stuck to the windscreen behind the rear view mirror?

So I've got the wires and sensor and the switch it must be down to the coding.

Or something is broken. You can check what the light sensor is reading with VCDS and you should also be able to check the light switch position.
