2014 SL63 hum/vibration
Hi folks, writing in on behalf of my uncle who owns a 2014 SL63, which has developed an odd symptom. The car exhibits an intermittent hum/vibration which can be felt in the seats and the steering wheel. The best way I could describe it would be a pump type noise, like a sump pump or vacuum pump noise. It happens sporadically, more so at idle or slow speeds. It adds resistance to the steering. It usually lasts for 10-20 seconds at a time. Nothing specifically seems to trigger it. No warning lights or messages on the dash. Vehicle has approximately 25,000 miles. Any ideas on where to look? Any advice or suggestions would be appreciated!

Though the cars are similar, the correct forum is here. https://mbworld.org/forums/sl63-amg-sl65-amg-r231-190/
