Hi guys. Just bought a 67 play CLA45, 6k mileage. Absolutely love it however after reading some things on here I’m starting to worry about common occurring issues. Still have around 9 months of warranty left so looking for an opinion on what’s worth pestering the dealer about and what’s considered “normal”.
- there’s a rattle in the exhaust when the car is in drive sitting at idle, and then when you start to move off. More predominant in sport + mode. Mercedes has said this is normal and just the mesh in the exhaust?
- coming from an M140 there’s obviously a lot of differences, including the massive turbo noise! But there seems to be a constant whining coming from the front left hand side of car when driving, more noticeable at low speeds.
- when flooring it the car sounds great, however after shifting to second gear the exhaust noise disappears and then all you can hear is what I imagine is very loud turbo whine? Exhaust note returns in third
- when changing gear at around 3k revs, not pushing the car hard, there seems to be a “whooshing” noise coming from the gearbox. Similar noise happens when downshifting from similar revs.
