Hi, thanks for your reply! I'm not quite ready to read the fault memory yet. The warning light shows "engine control" and sometimes also "check vehicle battery charge". Had my last service about 10,000 km ago, currently at 189654 km mileage. Hope this helps. Do you have any tips on what I could check myself before visiting the workshop? Kind regards!

Hey, okay, good to know! The "engine control" warning light sounds like a problem with the electronics or sensors responsible for monitoring the engine. And if the battery warning light comes on, it could also be that the alternator is not working properly - so check the battery voltage. A multimeter can be helpful to test whether the battery has sufficient voltage (should be in the range of 12.4 - 12.7 volts when idle and approx. 14 volts when the engine is running). What you can check yourself: 1. **Battery cable**: Look at the connections on the battery - are they tight and clean? Corrosion can cause many problems here. 2 **Read out the fault memory**: As mentioned, this is really helpful. A diagnostic device can give you more precise information about which sensor or which part of the engine is causing problems. 3 **Check alternator**: If you have access to a multimeter, check to see if the alternator is charging properly. When the engine is running, the voltage should be around 14 volts. 4 **Check the fuses**: Also go through the fuses, maybe one has blown. If you have checked all this and still can't find a solution, then the only option is to go to the workshop. Sometimes there are really small things that you can easily fix before you have to have major repairs done. I hope this helps you for now! Best wishes and good luck!

Hi, I had a similar problem with my Mercedes A-Class (2017 model year). I'm not a professional, but have some experience with cars. In my case, it was a fault in the vehicle electrics that affected other systems. At the workshop, they determined that the fault was a consequential fault in the electronics ("fault results from a consequential fault in the vehicle electrics"). The best thing about it: it cost me nothing - 0.0 euros. So that I can help you more precisely: What messages or warning lights does your car display exactly? Have you already read out the fault memory? Best wishes and good luck!
