humming

Hello, I picked up a 2016 GLC AMG Premium yesterday, it has 20 inch Bridgestone tyres on the optional alloys. (255/45 R20 MOE) The car is great other than one rather annoying issue. At motorway speeds the car emits a humming noise from the tyres, this happens nearly all of the time a...

It has happened twice but it is definitely not down to road surface. Friday it happened after 25 minutes driving at 70mph but not noticeable at low speeds. Today, in the way to IKEA after a few minutes driving and at 70mph it came back. It disappeared when I got into town. I took the same route...

I've only just bought this car. I've sat in the car with the ignition off, (audio system off and heating system off as well), and I can hear a slight humming noise - perhaps like a small fan noise or computer hum. Can anyone shed any light on what this could be ? (or is this normal ?) Thanks in...

Had the C43 for a couple of months now and i'm loving it but there is one minor thing which is niggling me. When you drive along at a constant speed there is a humming/buzzing noise, maybe coming from the back of the car. The noise is only evident when you are on a very light throttle ie just...

I noticed yesterday after coming back from a 60 mile trip the fuel pump was humming and I mean really humming, not the light sort of humming one normally associates with an externally mounted fuel pump. And it was the same today. Now, I replaced the pump with a quality Walbro only 3000 miles...

Greetings. My first post in this forum: Collected my 2007 (old shape) C200 sport today. It has the command nav system and I have had a MB-4 bluetooth connector installed. It has synced perfectly with my iPhone 4. However there is now a permanent humming sound coming from the speaker (?)...

Somewhere in the midst of the "New C-class Owner's Discussion" there was mention of a humming noise inside the car when you switch it on. My apologies if this has been answered, but I was starting to lose the will to live while trying to find any further mention of the noise amidst the welter...

Had a whirring and/or humming noise which I could hear inside the car at low revs. Finally found out what was causing this :- Slightly low power steering fluid level. Topped it up and now all quiet again YIPPEE. Fluid container is just beside the water expansion tank under engine cover. Photo...

Hi all As a newbie to this site I have trawled the threads but not found the answer I need so here goes:- When I turn off the engine on my ML270 (W163 2001) there continues a whirring or humming sound from under the bonnet like a small fan or similar for a few minutes until it eventually stops...

Hi guys. I posted a topic earlier regarding a humming sound i'm hearing and thinking it was something to do with the AC. But now im very sure its not the AC as i have had it off for the past day. Im hearing what can only be described as a fan which is turning on and off every now and again and...

I am getting a loud humming on my speakers. I have tried different speakers and the same result, so the problem probably lies in the PC, anyone any ideas?
