DIC automatic control

[peter]

I have an Opel GT 2007. In most of Europe it is now prohibited to drive with the headlights on. All cars sold new in Norway, where I live, are therefore set up with headlights ON as default. You can actually not turn the light completely OFF while the engine is running.

Some months ago a problem with the automatic sensor, diming the DIC and the stereo occurred. First it started when driving through tunnels – DIC and stereo dimmed down as normal when I entered tunnels, but after exiting the tunnel it took 20 seconds or so before it turned back to normal mode. Now it has gradually become worse – lights in DIC and stereo don’t turn to normal at all, not even in bright daylight. Today, I tested the sensor by putting my iPhone in flashlight mode and lay it upon the sensor. Then it worked like it should, but it dimmed down immediately after I removed the iPhone.

This problem is really a pain in my ***, because I also have the “overheating problem”. So while driving in daylight I really need to keep an eye on the temperature.

Any suggestions?

left of your steering wheel there is a brightness control knob.
on the over heating air in the system .
use the search tons of info .
Norway beautiful country .

Certainly sounds like your light sensor is flaking out. Obviously you can replace it. Or you can bypass it with a low-ohm resistor to make it think it's bright and sunny all the time - but then you'd have to switch the 'brighter' (non-DRL) headlights on manually at night.

As for your overheating problems this could be one of two things depending on the symptoms. If it overheats at any time (even driving along the highway) then it's probably air in the system (or possibly a failed thermostat). If it only happens when stopped in traffic or driving slowly, then check that your radiator fan is operational.
