Title: Loud humming sound
Post by: stu646 on 29 March 2012, 13:16
When ever I drive for over 15 minutes, I start to get a loud humming sound, coming from the near side wheel, well think it is from there, sometimes hard to pin point.

It becomes louder and louder the longer I drive, but if I stop in a car park for say 5/10 mins then I can then resume driving without the humming sound starting again for the 15 minutes.

Also , it stops when ever I turn right or when my breaks are pressed...other than that , nothing seems to stop it

Sounds like a bearing, but I'm thrown by the '15 mins before it starts' bit.

Could it be that the first 15mins of every journey you make, is at a slow pace? Do you live about 15mins from a bypass or an A road that you HAVE to use to get anywhere? Bearings tend to drone louder at higher speeds.The absence of noise when turning or under breaking could suggest you are taking off, or increasing the load on the bearing, hence the noise goes away.

Just my penny's worth, hope it helps.

The noise was happening even at very slow pace yesterday too..was crawling home to Manchester during rush hour and it was humming when I was doing under 10mph.

As for the first part of my journey usually on normal A roads doing about 30/40mph, then I hit the dual carriageway and get up to speed.

Don't some places do a free wheel baring test?

Never done it personally, but so I've been told, if you jack up the entire front of your car, when you turn/spin the wheels with your hand, you should be able to hear if the bearing is fooked :undecided:

Finally booked it in to the local garage yesterday as could not go on with the bloody noise happening each time I wanted to drive longer than 20 minutes.

Wish I had not though, as completely f**ked for money now!

First of all they phoned me up to tell me after taking the car out to test the noise, they thought my front arm brushes were knackered. On inspection they confirm this and have now fitted new ones on both sides for £196.

Then we come to that noise. They say water is leaking on to the brakes, which when it becomes hot, they start to stick , hence the loud noise. This would explain why I only get the noise when driving after a certain time and why it stops again for a while after being parked up.

But, to fix it , they want another £268. So near on £500 it has cost me this weekend now. Not happy at all

Got it all sorted this morning.

Went down and talked to the manager and after looking at it again, he said the caliper was sticking when my car had been running over 10/15 minutes.

So he says I needed a new caliper , disc and pads. Caliper at £76, disc £22 and pads at £22

Labour charge of £67

How does this sound?

Also they cheeky thingy, charged me £5 labour charge for changing one lightbulb

Nope not VW , just a local garage which is suppose to have a good rep.

To be honest, told him to f**k off when I seen the £5 charge to change the lightbulb , as you would of thought after spending well over £400 they could chuck it in for free

im a tech at audi and have to say i'm miffed by the theory water leaking onto your brakes.  how can water leak onto your brakes? everytime you go through a puddle a big puddle water gets splashed onto your brakes. at best they just won't bite for a corner if you go through a torrential, deep one that is...

as for pad sticking....the sliders get seized which is quite common, they will then bind. this infact happend on my own golf. it got to a stage where it was really bad and that will not give you any noise, but wear down you pads drastically and if you're on a motorway your disc will get very hot and go blue and warped being that under heavy braking at high speed you could experience brake judder through the steering but no noise.

so i am miffed tbh ....

sounds like a very expensive bill. road noise is usually a feathered tyre, being a budget one, vags have a lot of road noise or if its a humming noise it will very likely be a wheel bearing. simply jack you car up, spin the wheel and hold the spring, if you feel vibration through it, that wil tell you if its the bearing if you can't already hear it.
