DIC automatic control
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.
