@Mustapha You are correct. The car has some premium options like leather seats. I must have overlooked that. But it still is a manual. If the clutch, flywheel haven't been replaced yet, you will face a four digit repair bill very soon based on the kilometers on the clock.
As for just changing the switch. That won't work on your current car. There is no switch for front fog lights and automatic halogen headlights. DRLs and the function for automatically turning on halogen headlights was introduced in cars from structure week 2010/44 onwards. Your car is a 2008 and doesn't support that "out of the box". You would need to build your own custom light switch by combining part numbers 31318937 and 30739300 for example. And you also would need to test which CEM configuration would work on your car for this function. And you might also need to add wires from the switch to the CEM as well as relais in the CEM. There is no guarantee that this is possible at all. VIDA and EWD contain allmost all information needed for this kind of retrofit, but it's up to you if you want to spend time and money for trying to get this to work. Comparing wiring diagrams and pin outs of the LSM and CEM from a 2008 and 2012 car would be a good starting point.
