Problems with Mercedes CLA Class 2019 diesel: Engine indicator light, loss of power and stalling at idling speed
(Translated from German)
Summary of the thread
A 2019 Mercedes CLA Class diesel is experiencing issues such as the check engine light being on, loss of power, rough engine running, jerking during acceleration, and stalling at idle. A potential cause suggested is a defect in the activated charcoal filter, which was a similar issue in another Mercedes model. It is recommended to have the filter checked at a garage to confirm if it is the source of the problem.

Hi, thanks for your quick reply. My car is a CLA Class 2019, diesel. The current mileage is 187405 kilometers. The last service was only recently and the mechanics found nothing. A defect in the activated charcoal filter could really be the cause. I'll have it checked at my garage. Thanks again!

Sure, no problem, always happy to help! Your car already has a few kilometers under its belt, so problems like this can sometimes occur. The annoying thing is that you are often at a loss as to what the cause might be. I'll keep my fingers crossed that it really is just the activated charcoal filter and nothing more serious. Next time you're at the garage, make sure you have it checked and tell them about the symptoms you've noticed. Hopefully you'll be able to get back on the road without the constant fear that your car will stall again! Feel free to get in touch again if you have any news or further questions. Have a good trip and hopefully see you soon!

Yes, you're absolutely right. My Mercedes has had quite a few miles on it and things like this happen. It's just so frustrating when you have no idea what the problem could really be. Thank you for your support and I will definitely follow your advice on my next visit to the garage. I will definitely let you know what comes out of it. Thanks again and see you soon!

Servus, The description should definitely indicate an error in the error memory. That would narrow it down considerably in order to find a solution. MFG

Hi, I've had similar experiences with my 2017 Mercedes A-Class diesel. I'm not an expert, but I do know a bit about screwing things up and so on. I had the problem that the car kept stalling when stationary and so on. I then went to my trusted independent garage and they took a look. And the activated charcoal filter was defective, which could also be the reason for the symptoms you describe. They replaced it and I paid 275 euros for it. Since then, the car has been running like clockwork again. Can you tell me more about your car, perhaps the exact model and mileage, then I might be able to help you better. I hope that helps you!
