Recently purchased my 2018 cla 45 amg and am noticing a loud whine when accelerating. It’s only there sometimes after I have been laying into it a bit. Car has 45,000 km on it so still fairly new I’ve put on 15,000 myself and only started noticing things recently. It sounds like possibly the clutch for the transmission but it’s so loud I can hear it in the cab over the exhaust when it’s turned on. I took it down to my local Mercedes dealer shop for a service and to have it looked at and they told me the noice was normal. So that’s why I’m here asking if anyone else has the same noise or has experienced this same thing.
