Problems with Mercedes CLA Class 2019 diesel: Engine indicator light, loss of power and stalling at idling speed

Shaking while idling

Check engine light on

Unsteady engine

Jerking on acceleration

Stalling while idling

Loss of engine power

Hi guys, I have a problem with my Mercedes CLA Class 2019 diesel and I'm really hoping for your help. There are some symptoms such as the check engine light is on, loss of power from the engine, rough engine running, jerking when accelerating and constant stalling at idle. Everything wobbles when I'm idling. I have a hunch that it might be the tank ventilation system, but I'm not sure. Have any of you had similar experiences and can tell me what your garage did to fix the problem? Many thanks in advance!

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!

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
