GTI 337/20th Anniversary :: Road Noise Especially At Lower Speeds And Decelerating To Around 20 Mph
Apr 30, 2009
Recently purchased an '05 GLI (my second mk4) and it has the stock RCs and Eagle F1 tires. They are good on tread, wear pattern, and pressure, but seem to be making an awful lot of road noise, especially at lower speeds and decelerating to around 20 mph. as I read in one post "it sounds like a semi-truck". When I test drove the car it was still in winter mode and there were no noises or pull and so I do not suspect any mechanical issues.
It does not result in any real vibration that you can see in the wheel, but you feel the buzzing. the steering is straight and true as well with no pulling left or right. IT'S JUST LOUD!! lifted the front end and shook the front wheels. the bearings seem nice and tight with no wiggle. I was going to remove the tires and rotate, or put on the spare to see for a diff, but the BBS tool for the center caps is a POS and I couldn't get them off. So ultimately I'm looking for some vortex advice on this noise, its causes, remedies, and and anything else I should be looking for.

So I had the cv joints and boots replaced last year. When I turn at low speeds I get a clicking and some road noise, when I turn at higher speeds I get a lot of road noise. I feel like its a combination of strut mounts and wheel bearings?

I started noticing the noise about a week ago, When i seem to let of the gas or even once in a wail push on the gas Hear a "CLICK" noise, this is not when pressing the brakes at all only when letting off pedal?
I am thinking it could be transmission, but have read it could be a few thing, From the brake pads to CV joint to trow out bearing, Axles, Lightened flywheel, Motor mounts, etc. But i am unsure where to start, Its and O2M 6spd tranny in my 20th, with lsd installed, lightened flywheel, VFmotormounts...

Ok my 2002 337 has 87,600 miles on it and for quite a while now its been making a lot of font end noise, its most noticeable at 25-30 MPH, decelerating or holding a steady speed, it disappears when your accelerating hard, and at high speeds. But the noise is horrible, its like a buffeting
Its been serviced regularly, since the noise I've done, new front brake rotors, new pads, wheel bearings, inner and outer CV boots replaced, CV joint checked. My local mechanic who's done a lot of work for me isn't sure what to think, he said try rotating the tires because it may be tire noice on the road? Im running some generic tires, the brand on the tire says "sunny" but they appear to be a good performance tire, and handle well

I get a wobble only when on the brakes when I am decelerating at about 40 mph. I have brand new tires on, 1000 miles maybe, with I think a good balance Started happening a couple hundred miles ago... What do you think? Warped rotors? bent axel? It's definitely coming from the front.

OK, maybe I'm just spooking myself, but I've been getting poorer gas mileage than usual as of late, like 4 to 5 mpg less. I used to get 30+ when I took my car to work, but lately I've been getting 25 to 26 mpg. I calculated it out and it seemed less still, though I didn't do a very accurate calculation.
The other day, I felt like my ESP was kicking in early because my tires are getting a bit old and bald, so I turned it off for my drive home. I immediately noticed that I felt like more power was available (though that was probably my mind playing tricks) and my average MPG for the trip shot up to the 28.5 mpg range with some spirited driving.
Where the ESP or ASR has caused lower MPG? I replaced my MAF sensor recently because it had gone bad, or at least I was fairly certain it had, but now I'm not sure. I also have coil-packs due in the next few thousand miles or so as well, but this seems sporadic. I diagnosed the MAF (which the car was getting around 22MPG before the change) by disconnecting it. It shot up to the 30MPG range with it disconnected, but thinking back, my CEL as well as the ESP light came on. I'm wondering if my ECU turned off the ESP with the MAF disconnected and that is what increased my mileage, not the bad MAF...

I just put on some brand new Bilstein shocks/struts with new mounts and some Neuspeed springs. It seems like the rear sits lower than the front. Maybe some polo bushings to bring the front down a bit? No stereo stuff of anything in the trunk..

I want to put lower grill fogs in my GLI, but was concerned about them interfering with the intercooler system. I currently have an upgraded SMIC, but was concerned the lower grill fogs would impede a significant airflow to the SMIC.
Additionally, I do plan on going to a FMIC in the near future and wasn't sure if people were able to run the fog lights while still having space for the FMIC piping.

For some reason My car won't boost like it used to in the upper gears. 1st, 2nd and even 3rd I can still boost around 18 but once I go 4th, 5th, 6th my boost get lower and lower to the point the I get only 10psi in 6th gear. The car also seems slower a doesn't spool that fast like it used. i checked most of the hoses, even my intercooler pipes which were leaking before and everything is tight. Could it be my DV which is still stock or should I look someplace else?

I just had a 2008 Jetta 2.5 as a loaner car and it made me realize how rough our GLI's ride over bumps on the road. This thing rode like a cadillac and it was a really pleasant change here in new york city where the roads are terrible.

Whenever I take a turn my seat slides side to side, both bolts are tight in the front. Is there a way to tighten the lower half of the seat so it doesn't move?

After installing my FK Streetline X Coilovers I noticed my rear driver side was sitting lower and and the wheel had more camber.

I've never had this happen before or never heard it. but yesterday for the first time as I was driving I could hear a really tin canny sounding rattle. I'm not sure if it was from the wheel well area or under the steering wheel in the dash. I only noticed it when I was at lower RPMs in second gear. (And its not the typical MKIV rattle sounds)...

I am installing my coilovers on my gli and I have everything installed but the passenger side coilover. I cant even remove the old strut because the damn lower strut mounting bolt is seized and I've been trying for hours to remove it at no avail. I have used pb blaster, my heat gun, and my sweat. I dont have impact tools, just my ratchet..

Having problem with my car (2001 Elantra GT) - over the last month or so it's been occasionally making a very loud (not but consistent) grinding noise coming from the front of the car when decelerating at low speeds. The noise sounds like gears slipping over each other but cuts in and out. It's pretty loud and not a nice noise to hear! Sometimes it makes the noise when I brake firmy but not until I reach lower speeds... mostly it's just when coming to a stop, but it did it once last week when I was pulling very slowly out of a parking spot and not even braking.
As it's become more frequent (going form maybe once a week to several times every car journey) I have started to feel something in the brake pedal also, like there's something kicking it from behind. I took it to a mechanic and had to pay a ton of money to get a broken front left ABS ring replaced (it also had the front right ring replaced in May), and within 2 minutes of driving away from the place the noise was back. Before I spend even more money that I don't have on taking it back for extra diagnosis.
I'm told that this is almost certainly the ABS system that has a fault even though the ABS light never shows except when I start the car, and I've taken the fuses out of the ABS in order to confirm that it is. I haven't heard the noise after a few days of driving with ABS unplugged so I think we can be reasonably sure here. Is there anything that I can check myself or test (I'm not very handy when it comes to cars) or can you tell from this information what it's likely to be? Other things that I've noticed with the car which may or may not be relevant are:
- the warning lights for brakes, ABS and TCS are all lit with the fuses for ABS1 and ABS2 taken out. I take it this is normal for all 3 to illuminate with the fuses out?
- since unplugging the ABS I've noticed a slight metallic squeal from the brakes as if the brakes are worn down. Didn't notice this before I unplugged ABS though it may have been there, not sure.
- sometimes when going over a speed bump or just a minor imperfection in the road I hear a clunk in the front of the car and feel something move in the underside of the car. Happens mostly at lower speeds also, but not if I go over the bump really slowly.
- in the fuse box when I took out the ABS fuses I noticed there was a bit of minor melting/brown burn marks on the top of the connections marked (iirc) ECO3 and ECO4 on the diagram (large white connectors). Is this anything to be concerned about?
- sometimes when I have air coming into the car through the air vents it will become significantly warmer for a few minutes, then slowly go back to normal. Can't think of any circumstance that links the times when this happens (eg. speed, weather etc).
- the oil pan has a leak which is on the list of things to fix when the car works properly.

Well I've been noticing that when I'm slowing down from higher speeds (50 mph or so) my steering wheel is shimmying a bit. Also I just started to hear my front passenger brake squeal a little. Well when I went to visually check the brakes, the pads seem VERY thick! Is it normal for them to start to go bad even with such thick pads? They are like 1cm thick. Also the rotors did seem used for sure, maybe 1mm worn down or so from the outer lip which is raised (I hope you understand what I mean), but they weren't scoured or anything. I suppose they could still be warped? I figured with such big brakes I wouldn't run into that problem. The car has 70k on it and the pads have been replaced once and rotors turned at 25k by the previous owner.

I'm having issue with my Camry making noise recently. It usually happens at lower speeds ~50km/hr, city driving. When going over bumps, rail road tracks, bridges, etc. it makes a metallic clinking sound that kinda lasts when the car is bumping up and down, if there are multiple bumps, it seem to be worse.
Going at highway speed and on smooth roads, doesn't seem to be much problem, or it occurs much less frequently.

I'm experiencing noise when sunroof is open. This is happening at lower speeds and at last couple of sunroof positions. I guess it's vibrations or some weird effect. (Golf MKVI 2.5)

Occasionally, when braking at lower speeds (i.e. coming to junction) I get feedback through the pedal almost as if the ABS has kicked in....braking is not very effective when it happens. I can also hear a pump type noise going. If I lift my foot and re-apply it clears and normal braking returns. In fact, sometimes I can hear the pump noise going even before I brake....always at low speed (sub 15-20 mph) doesn't happen when driving at higher speeds.

A few weeks ago we notice a noise and grabbing from the front wheels. Noise was at lowers speeds only. Dealer did the following work.
Replace steering lock assembly and program
Replace left and right lower arm bushings
Replace outer cv boot, grease and repack
Extended warranty covered only steering wheel assembly and car rental.
They also said that the tires need it to be replace due to capping. Tires are only 9 months old. Replaced tire under warranty Potenzas G09 and di alignment that was way off. Two months ago was ok and drove less the 1,500 miles...
