noise

Hi there hoping someone can help with this! Occasionally when driving a very loud air leak noise appears from the brake pedal, and this noise disappears once I press the pedal and activate the brakes. Anyone know Why would this happen? And whether it is expensive to repair. Then takes feel...

I have just purchased my first Mercedes c250 sport from a local dealer, I have had it a couple of days and can hear a bad knock on the front end , I have had to both my local garages and none of them can find anything yet both of them can here the knock any ideas ??

Not sure if this could be related to diff/transmission; I get a slight howling noise when going over 30mph, it is very quiet but I do notice things like that, the tyres make a noise but that's separate I think, that's more of a 'whomp whomp' noise, this new sound I often get is most often upon...

I am interested in a 2011 W169 2000 litre manual diesel. Two queries - I appreciate diesels are noisier than petrol but is it really noticeable ? Would like a reasonably quiet car. Is the acceleration better in diesel than a petrol ? Thanks

bit of an odd one. i have a 57k 2005 cls 500. when driving around multi-storey carparks i hear a noise that sounds a bit like two stones being hit together. it seems to come from the front left of the car. no error messages on the suspension and the car drives perfectly. any clues?

MY E500 had a problem that ruined it for me: a low pitched tapping noise only heard on acceleration. I’d had a couple of very experienced people look at it, including the fantastic Terry from Wayne Gates. Terry eliminated lifter noise, transmission or cat noise and eventually suspected the worst...

Got a 2013 C-Class facelift that came back from a service and it's first MOT about 2 weeks ago. The last couple of days whenever I go over a bump or a speedbump etc I hear a loud "PPPFFFFFTTTTT" coming from the passenger side front or rear tyre area - kind of like pneumatic air being released...

hi all need some help here or a miracle , i have real problems with this car , first got it about 4 months ago , drives like a dream until i took it to have a full service , brakes , filters , transmission fluid , filter and gasket , etc , after 5 mins of leaving the garage to the car started...

I'm assuming as I can't see anything physically on the outside of the car that this noise is not rear parking sensors but an annoying warning that you've engaged reverse? If so how do I disable it as it's bloody annoying, I know I've selected reverse because I had to move the gear lever to do...

i am hearing a low clicking noise from front wheel when turning right, clicking gets faster when speeding up, nothing when turning left , any idea's ? was thinkink a screw/nail in tire but cant see anything

Good Morning All, Not much of a poster of sorts but looking for a bit of advice. Car Details: Mercedes C180 Coupe Kompressor - Engine: M271 Fault: I've noticed a whirring noise from the engine which has only showed up the last week. The best way to explain it is that is sounds like a computer...

Hi all When i brake there is a knocking noise coming from the left hand side. It only knocks once and varies in loudness from a quit knock to a louder one that can be heard outside the car. It doesn't necessarily get worse or better with speed or force of braking. Can anyone suggest what it...

A few minutes after start up, I hear a few seconds of water gurgling behind the heater vents on my C180. Related info : the heater dial goes from 0-28, but 0-20 all feels cold, then suddenly it will start blowing noticeably hot only when it's turned right round to 25. A few months ago the...

Gentlemen, Ladies, Having replaced and adjusted the centre bearing of the prop-shaft according to all the postings, e.g. lower the vehicle and rock it backwards and forwards or push it around the place before tightening the locking nut, when I change in to fifth there is a transmission noise...

My wife's SLK350 makes a chirping noise for 3 seconds every 30 seconds for a matter of hours after switching off on a hot day. The noise stops if you re start the engine and then switch it off. The noise is coming from somewhere near the bottom front corner of the engine in the area near the air...

When I apply power from a slow rolling start or a standstill I hear a squeaky noise . Last just a second then goes . Could it be a broken mount or suspension component. Getting annoying now. Such a pleasure to drive apart from this new squeak noise. Any ideas on what it could be. Sounds like its...

Hi everyone out there, Does anyone have any words of wisdom please? Driving along M1, then onto M25 the car started making high pitched noise once over 60mph. It is a 2008 reg, therefore it still has timing chain as opposed to belt. Performance wise, no problems and no warnings or codes...
