Question about 1999 Audi A4

5 Answers

Humming form the rear tyres, I have had them swapped over but the problem still persists. Water leaking into the boot lid, the rear integral lights have been changed under warrenty but this has not solved the problem. It's worth noting the car is only just over a year old and has covered 23k miles.

Wheel bearings going on the A4 at 23K miles??? I have to say highly unlikely.

I have owned two of these both B6 chassis - sold first one at 120,000k miles - never had a wheel bearing issue in all that time. now on to second one (year 2004) - has 130,000 miles on it and definitely no wheel bearing issues. Drives like it had 10,000 on it!!

These Audis are tough as old boots mechanically and contrary to what others are saying here wheel bearings are most definitely not an issue with them especially not on a one year old car.

My concern would be firstly - did you buy this car brand new? Was it a demo model? Are you 100 percent sure it has not been the victim of a rear end shunt which has been poorly repaired? This would explain both water entry into boot from poor repair and body sealing and also humming from rear if cars telemetry was not properly realigned.

If you see evidence of unusual tyre wear at the rear I would advise you to have the car checked on a 4 wheel alignment machine to rule out this issue.

This car is surely still under manufacturers warranty and I would be strongly pushing to have these defects checked and properly rectified by the dealer.

Do let me know how you get on and a rating would be appreciated.

I agree with the wheel bearings being the issue - they're notorious on the A4.

It is common for the rear wheel bearings to go between 60-100kms. The humming is the rear wheel bearings not the wheels. This is the third one that I am replacing tomorrow.

Hi, can't help with the tyres but might be able to with the water in the boot as my 99 A4 does the same, after hours of standing in the rain i found it was getting in behind the rear window, behind the bottom cornors of the rear window is a join and on mine looks like they have not be filled properly leaving a hole so the water runs down the side of the window seapping behind the black trim (these are just for apperance they dont hold the window in) then down the side of the glass till it reaches thease holes and into the boot. on mine i pulled the black trim pices out and filed the holes with sealer and put the trim back in so it never notiecs, but you probably won't want to do this on a one year old car, so i'd say back to audi with it, hope this helps

Am getting water in boot in the tyre well any one any ideas


Assuming no holes in the floor pan, it could be the rubber seal around the trunk lid. If you use a garden hose to wet down the outside rear of car, then open the trunk for any new sign of wetness, er, more wetter, lol.

Humming noise at 80kph at rear, would worn spring bushes cause this


unlikely--- humming noise is from a vibration caused by failing drive line joints , bearing failures, out of balance drive shafts , failing rear engine mounts, worn slip joints, worn output shaft bush in the transmission housing
it can also be from bad tyres or tyres with a regular tyre pattern in the tread
To understand this you have to closely inspect the tread pattern of tyres and you will see that the pattern is not consistent around the tyre as that consistency is what gives a noise ( example is the old bar tread tyre and the road hum that was produced on hard surface roads)

Miata 1991 w soft top,my daughter bought. First hard rain water was in the trunk, in the back of interior and driver's floor board. Plus we heard the sloshing of water noise. More like waves. We used


the water may be in the rocker panels of the body ( that area that runs under the doors from mudguard to mudguard on the sides ) there will be drain plugs in the under side that will let the water out. I would be checking the rear window for leaks and the boot lid seal. Check the boot seal for security by placing a layer of Vaseline on the boot lid where the rubber will be touching and close the lid. Open the lid and see where the vaseliene has not been disturbed and that will be the leak area

My mitsubishi eterna leaks when wet outside. It is becoming a big problem as mold is starting to form. I think it happens in the boot but where and how do i fix it?


check the sealing rubber around the boot opening paying attention to the rubber condition and the metal lip that it is fixed on.. Check that the boot lid is properly adjusted and touching the rubber all around . Check the sealing around the tail light assemblies. Check for rust in the floor of the boot . If you have a fender mounted aerial then check that the water is not getting in by the aerial and fitting

How to fit a boot lid on a 1999 ford cougar


Firstly, open it up, remove all wiring, any light lenses which you need to switch over, lock, inner lining, number plate brackets, lights, etc.

Then, once everything has been removed, undo the bolts which hold the lid to it's hinges, and take the lid off.

Reverse the procedure for fitting the new lid.

Close the new lid gently at first as it may not locate well on the first attempt.
If it's all askew, then slacken off the hinge bolts and position the lid to how it closes well. Once in the correct position, tighten the hinge bolts, and you're almost done.

Final step: Run some water over the lid for a while and then open it up to check for any leaks.
If you do have any leaks, then as extreme as it sounds, climb in, close the lid and have someone run water over the lid, while you lie inside with a flashlight/torch and look for leaks.

Good luck.

Boot fills with water after heavy down pour on 2001 s type sport , some times engine miss fires ,,,until i dry boot out then runs fine ,,boot seal looks ok ,how do i stop water entering the boot...


I would suggest that the rubber seals on the boot surround are in fact faulty or the boot lid is very badly aligned. (Has there been an accident repair to the boot area?)

1. Check the seals again - every inch - and check for movement as some of the rubber adhesive which glues the rubbers to the body work may have broken down.


2. You should be able to replicate the problem with your garden hose. Run the hose full bore over the upper section of the boot lid and over the rear window for a few minutes. As soon as the surface water has cleared the exterior body work open the boot and you should be able to detect where the entry point is by inspecting the edges of the boot compartment and the boot lid.

One person I know popped his wife in the boot while he ran water over the boot area to find a troublesome leak point. I would not recommend doing that.

Water in boot


1st off is this a reoccurring and persistent problem you are having, or is this the 1st time you noticed the water , if it is an ongoing problem. your going to love this one, it will require trust and another person, a light source and a water supply, are u with me so far.
someone needs to climb in the trunk with the light while the other spraying a stiff stream of water at gap between lid and fenders, the trim around the rear windows tail lights at every angle." remember to have your cell-phone with you in the trunk", you never know what your friends think is funny!

Loud humming while driving 2005 toy. camary. had tune up and transmission filter and fluid changed 2 months ago, was fine for a while but started humming loud again this week?


Please check your tyres.
if it is due to the tyres put the front tyres to the rear part.check if the noise moves to the rear.did you just replace the tyres?
there are brands offering cheap tyres which make noise .
