noise

Help !! can anybody give any clues on this engine noise -!! I have a 4.2 CL ( s class coupe 1997 ) and I have a loud tap that appears to be coming from top of the engine on passenger side. It increases with engine speed - the car drives as smooth as it always does , the oil pressure is good - if...

Hello I have an S205 on order and have read quite a lot on the US forums about the W/S 205 suffering from excessive wind noise and needing acoustic glass to sort the issue out? Is this a known problem with European cars and if so does it still affect the new builds - got a build date of...

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...

Hi All, Just about to nip over and get an MoT for a 1984 280CE - hopefully. The only problem during the pre-inspection was the hazards not working - indicators OK. I pulled the boot light, interior light, antenna, radio and haz switch, put the fuse back and got a pop with a buz by the...

quite a lot of valve/tappet noise when it's idling - is that normal for this engine ? can't hear it inside the car, just when you open the window or are standing outside. not a big deal, just wondered. otherwise it's great - I swapped out of a 2013 C63 6.2 for this below and I am not feeling...

Hi All New around here, been snooping about for a few days while I consider my next purchase. Currently have an Audi A5- lovely car but I made the wrong engine choice so I'm bored of it already. Previously used to much faster. So a CLS55 is peaking my interest, the indecent power is...

Hi all...I have a 2008 c220 cdi pre blue efficiency with the om646 engine and under light acceleration in top gear it makes a tinkling noise just like pinking noise heard in a petrol engined car. I am unfamiliar with diesel engines as this is my first but would you say this is normal or if it...

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...

Hello I have a C43 Estate on order and am considering adding the performance exhaust! I can't test it as it is not released yet and do not want to create a massive base bin inside the car due to the exhaust droning! So.... Has anyone got any experience of the cabin/ exhaust sound inside the...

Hi guys. Firstly, as I am new here I would like to say hello. It appears my fully serviced e320 is having a very weird issue I've never seen before. It's sounds like it's got an issue with the fuel / oil pump or injector - I've also been told that it could be a tappet. No idea, 97k FSH no...

Hi guys - grateful for views - I have a noise coming from the wheel(s) in my 1995 W202 C180 - which sounds like this: https://youtu.be/o7UpHcFAqe0 Only really prevalent at slow speeds. Do I need a replacement wheel bearing or does it sound like something else? Thanks! Jamesie

On half throttle I'm getting a surging/rubbing noise that I can't identify. It is intermittent and sounds like if your power steering fluid is low and you go around a corner but my level is fine. Cant see any belt wear/rubbing anything either. I haven't been able to replicate noise via revving...

Hi, not all the time but alot of the time, especially after a drive say 10+ miles my car makes a very strange noise only when moving from the gearshift area. Doesn't always do it and sometimes never at all, have found going uphill makes it louder and sometimes it can be really loud like the...

I wonder if anyone can help me pinpoint where a noise is coming from...:doh: When driving and I turn even slightly to the right (even at low speeds), I get a noise... Now, don't laugh but the best way I can explain it is "Awubwubwubwub" from the rear of the car. Not very very loud but loud...

Hi all, This is hard to explain if you don't hear the noise I do. When I unlock or lock my car (53 plate W211) there is a high pitched electronic tone that is coming from within the engine bay. The noise is loud enough to be heard from within the car but is muffled once I close the door. It...
