Mercedes CLA Class: Engine failure and electrical problems - help needed

Weak battery when starting the engine

Dim or flickering lights

Engine shuts off by itself

ABS/DSC system is not working

Hello everyone, I have a problem with my Mercedes CLA Class (diesel, year of manufacture 2015, approx. 190,036 km driven). The engine suddenly stops, ABS does not work properly, the lights flicker or are dark and the battery seems to be weak when starting. My guess is that it could possibly be the alternator. Has anyone had similar experiences or can anyone recommend a good garage where such a problem can be solved properly? Unfortunately, I had a bad experience last time. Thanks in advance for your help!

Hi mate, I had a pretty similar problem last year with my Mercedes A-Class, diesel, built in 2012. It turned out that the engine control unit was faulty. The symptoms were exactly like yours, engine stalled, ABS not working properly and lights flickering. This was a serious problem, but after it was fixed at the garage, I didn't notice any more problems. You should take your car to a garage immediately. Hopefully that will help you!

Thanks for your reply. Your insights are really helpful and it sounds like it might be similar with my car. Do you happen to remember how much money you had to leave at the garage to get it fixed? And have there been any subsequent problems related to the fault at the time?

Moin Moin! Sure, I still remember the repair costs. I had to fork out a thousand for the repair of the defective engine control unit. But rest assured, since the visit to the mechanic, the fault in the alternator was rectified and I had no further problems. The car has been running perfectly ever since. I hope it will be the same for you! Good luck, buddy!

Thank you for your quick and detailed reply. That reassures me a little. Of course, a thousand is a lot of money, but if everything works again afterwards, it's worth it. I will definitely have it checked at a good workshop. It's always good to hear other people's experiences before embarking on a repair like this. Thank you very much for your help! I'll get back to you as soon as I have any news. See you then!
