Loud engine and roaring exhaust in 2010 SLC Class: Possible causes and workshop recommendations wanted

Hey, I drive a 2013 E-Class, and had similar problems with my exhaust flap. The symptoms sound pretty similar: loud engine noise and a roaring exhaust, especially when the engine is cold. In my case, the exhaust flap was actually defective. It ensures that exhaust gases are routed out correctly - if it's broken, this can cause the noises you describe. As far as the garage is concerned, I would advise you to ask your friends or look online for well-rated garages in your area. That's how I finally found a good garage that helped me. But don't worry too much, replacing the exhaust flap was quite straightforward for me and got my car running again. So all in all, it's a serious problem, but it can definitely be solved. Hope this helps you!

Hey, thanks for your quick and helpful reply! Your experience seems very similar to my situation. That makes me feel a bit better, but of course it's still worrying. We both seem to have had the same stress with our cars. I'd be interested to know how much the repair cost you? Can you remember it? And have you had any further problems since then, or did your car run smoothly again from then on? Thanks again for your help!

Hey, yes, we've obviously both run into the same car problem. But as I said, it's solvable! As for the cost, well the replacement part and the labor together cost €190. Pretty fair considering the problem was completely fixed and my car has been running like a charm ever since. As you know, after the repair is before the repair. But I haven't had any problems with the exhaust flap since then - seems like my mechanic did a really good job. So, I hope this helps you and you get off as lightly as I did. If you have any more questions, keep them coming!

Hey, that's a real relief to hear. 190 sounds really fair, especially if it fixes the problem completely. And yes, it definitely helped and I feel much better equipped to tackle the situation now. So I'm going to take the next steps and look for a good garage near me. If I have any more questions, I'll definitely get in touch! Thanks again for your help and advice! I wish you trouble-free driving with your Benz. Take care and stay healthy!
