whining

Hi All, Im really sorry if this thread exists already. I have 2005 C180K, i bought the car about 2 years ago with a whining noise, which i was told when viewing the car it as the Kompressor, i really like the car so didnt want to miss out on the deal. During the time that i had the car...

Good afternoon. My newly bought C320 Coupe has got a whining noise that starts when engine warms up, stays on low revs but disappears on higher . I had a look at the Climate control fan, it was quite, I had a listen using a stethoscope in engine bay and found the source of the noise to be...

Well, that was an eventful day today... ... my 2013 S212 E220 started making a whining noise whilst accelerating through the gears after 30 odd miles of motorway driving. Called Mercedes roadside assistance once I got to work who sent someone out within the hour. We went for a drive and...

Hi, I just drove from Glasgow to Liverpool to pick up a 2009, cl500, car is stunning and test drive etc was perfect, however after around 50 miles and in traffic i noticed a whining sound that went with revs, i stopped later for a break and when i started it again it was all good, however when...

Hi guys, after all the trouble ive had and just having had the car fully serviced two days ago, the fuel pump has started making a high pitched whine noise, and i mean hi volume noise. Ive used it for a couple of days and everything was fine, then i started her in town today and all of a sudden...

Hello! Ever since I got my 2006 cls350 it has had a whining noise from the engine. Using some flexible tube held to my ear like a stethoscope I located the source of the noise. 2 of the pulleys at the front of the engine that the serpentine belt goes round were the problem. One was just a...

So having had my E55 a while now, the one thing that started to get on my nerve was the whining. I hadn't really noticed it a lot when bought,to be honest, being a big S/C I accepted it. But over last few months I really started to notice the 'whine'.. Long story short, after having kittens...

Hi, new to this site so bear with me. I've got a 2008 Merc Viano Excl 3.0cdi done 130,000m. She's been great up until the last 6 months until I started noticing a bit of a low pitch whining noise at between 55-65mph. It has steadily become more noticeable and only happens when you are...

My '04 E55K has a (fairly low-pitched) whine from the front of the engine. It is worst when stone-cold, rises and falls with engine speed, and varies slightly in pitch when I turn the steering wheel, so I'm 99% certain it is the hydraulic pump. The fluid level is correct in the reservoir, and it...

Hi to all, hoping to get some ideas as to what the Whining noise is coming from the front of my W210 e240 2.6 V6 motor is, When running it sounds almost exactly like the belt whine you get from a supercharged motor and increases in pitch with raising the RPM, all of the ancilliary wheels ie: P/S...

I have a E250CGI with the M271 direct injection petrol engine. It is a M/Y 2010, but the car has only 30,000 km on the meter. Some time ago, when driving with my windows down I noticed a whining noise or tone, at say 1-2 kHz, that is proprtional with the engine speed. It is not the...

Hi All, I have a 2003 W209 CLK55, on start up and running it had a whining noise. It doesn't seem to be pulley or belt related. Its had it since I bought it in the summer. I don't believe its the torque converter as I've had that replaced, and the noise was there before and after. It doesn't...

Hi everyone, I do not know whether it is normal or not but my Mercedes W220 makes a whining noise in low RPM (below 2000 RPM). However, the whining noise stops above the 2000 RPM. The sound is present in both acceleration and deceleration. There is a very slight vibration when there is the...

Hi everyone, I have some questions concerning the whining sound of Mercedes engines. From a dead stop, I made a big acceleration and I noticed that the engine made a supercharger sound. I have a S500 and as far as I now, my car does not have a supercharger. To try to clear things up, I made...

Hi, i am looking for some advice,when i first start my car up there is a whining noise coming from the front of the car,it quietens down a little when warmer. I have changed the ina Deflection Pulley Drive Belt Tensioner also the drive belt with a ContiTech Drive Belt,but alas this had made no...

I have just fitted a pair of K&N air filters to my SL350. They were a straight swap for the standard filters. Apart from hearing more easily the engine change down gears with the auto box there is a high pitched whine, almost like you hear went the wind blows very hard, when I accelerate. At...

Hi all, I hope someone can give me a pointer on the below. The SL likes to make a whining noise when turning the steering wheel when she's cold. In a straight line, all is fine, but turn the wheel left or right and this sound eminates from the front. It doesn't do it once the engine gets...

Took the CL600 to the dealer to investigate a ????strange noise from the front of the vehicle, best way to describe it is the sound a toy car makes when in motion, a sort of whining noise. Noise increases/decreases with engine speed. noise is evident whether car in motion or static, in gear or...

Hi all, There is a whining under the car now. How can I know if its the propchaft bearing or the differential? Its the same if I put on neutral while moving, the sound change with the speed same as on gears. Cheers.

Hi, My C320 seems to be whining all the time, exactly the same whine you get from a supercharger. (No it doesn’t have a supercharger) It’s more noticeable at low revs. Pulley & idler were replaced by MB about 9k miles ago. Any advice please guys? What could this be? It's a 3.2V6...
