Wow, great, thanks for the quick feedback! That sounds like a great solution, I'll definitely have mine checked. But tell me, can you still remember what you ended up paying for the repair? And have you had anything else come up since then? Thanks again, you've really helped me out!

Hey, no problem! The repair of the defective waste gate valve cost me a tidy €860. But since then everything is back to normal. Since I've been to the mechanic, the fault with the boost pressure sensor has also been rectified, so don't worry, everything is running like clockwork again and I haven't had any more problems since. Hope it goes just as smoothly for you. Good luck!

Yeah cool, that sounds like a plan! I'll definitely ask the garage and give them the tip about the waste gate valve. Your information that there was no further problem after that reassures me enormously. It's not exactly cheap, but what can you do if you like driving a Benz. Thanks again, that was a great help! Bye!

Hey, I just had a similar problem with my 2013 C-Class. Sounds like the defect is in your waste gate valve. That was also the case with my Benz recently. Jerking engine, black smoke, shuddering at traffic lights and loud hissing noises when accelerating are all typical symptoms. But don't worry, it's annoying but not really serious. I had to take mine to the garage and they replaced the valve. It certainly helped. The engine is now running smoothly again, no black smoke, no hissing and shaking, and the power is back where it should be. Check that with yours. I hope that helps you.
