Hey, thanks for the quick reply! Your description does indeed sound a lot like my problems, so it could really be the intake system. Do you happen to remember how much the repair cost at the garage and whether any problems arose afterwards? I hope my car will be back to normal after the repair. I would be pleased to receive further information.

Hey, no problem, I'm happy to help where I can! In my case, the cost of repairing the intake system was around €425. Not exactly a trifle, but since then the problem with the deviation in the intake volume of the engine has disappeared and my car is running like new again. No more problems since then! I hope you feel the same way and that your Mercedes runs like it used to when you have it repaired. Let me know if you have any questions or just how it turned out!

Hey, that reassures me a little. Of course, €425 is not a lot, but if everything runs smoothly again afterwards, it's definitely worth considering. Your experience sounds really positive and I hope it will be the same for me. I think I'll take my car to the garage tomorrow and have it checked out. Thank you very much for your help, it has helped me a lot! I'll let you know again how it turns out. Until then, take good care of yourself and always have a safe journey!

Hey, I actually had a similar problem with my 2011 Mercedes E-Class diesel. It ran as rough as an old tractor and lost a lot of power - I also had black clouds of smoke coming out of the exhaust. The engine warning light was also my constant companion. It was actually the intake system. A leak had led to an incorrect air/fuel ratio. That's why the engine was running rough and losing power. The black smoke is a sign that there is too much fuel and too little air. I can understand you being skeptical after your last experience, but this was definitely a serious issue that is best fixed by a good garage. I wish you the best of luck, let me know how it goes!
