#11 of 20 2004 Jetta Engine Tapping Noise by jetdriver1 Jan 16, 2008 (11:48 am)
My daughter just bought a 2004 jetta 1.8T. When the car is accelerating, I can hear a kind of tapping sound as the motor spools up. The car accelerates nicely with normal speed and tach indications. It almost sounds like I can hear the lifters, or valves or something. The salesman told her it was the sound of the turbo. I have never driven a turbocharged car so I don't know. Does anyone have any ideas what that low level tapping sound might be? Thanks. It is still under factory warranty and she bought a 5 year/100K extended warranty too so I am not real worried about it, but I would like an explanation of what that tapping noise is though.

#13 of 20 car screeches when hot by joker55 Dec 02, 2008 (8:33 am)
hey guys    wondering if you can help me out, ill try to make this as short as possible    I've got a 1999.5 Jetta, Auto, with 199,xxx km on it, a few months ago i noticed a "screeching/rattle" noise coming from underneath the car, it is noticeable after the car has been running for more then a few minutes or has had a good run on the highway    it does it when i have the car in Drive, and foot on the brake, i can hear this noise coming from underneath the car, closest to the front, i'd say it was coming from where the downpipe/cat is, also, ive put the Ebrake on with wheels chocked and got down beside it and can hear the noise, it goes away slightly when i put it in park/neutral, i pop the hood but dont hear anything in the engine bay    anyways, i went to the mechanic and asked if it was the Cat (i had a similar noise about a year ago and had VW replace it under the warranty and didnt really notice it anymore, probley cause it was winter time i.e windows up all the time) he told me that he suspected that it was the heat shield on the cat.......so i cut it off (my warranty was up anyways)    noise was still there    i go to a muffler shop and they said that it was the bracket where the resonator is, the exhaust was vibrating and going to the front of the car where the flex pipe is hence it sounds like screeching......so had that replaced    noise is still there    this noise is driving me nuts, simply because i cant figure it out, i know its not my serpentine belt or my tensioner, i had my timing belt and water pump done not too long ago because of another noise, so i dont think its that    has anyone had this problem or now what this problem is? i dont want to just start throwing money at in hopes it will stop, i'm just concerned its going to become something worse....    any ideas?    thanks in advance
#14 of 20 jetta noise in rear axle area, buzzing/humming sound by epullins Jan 24, 2009 (10:31 am)
I have a 2001 jetta, 1.8 T gas engine. I have a buzzing/humming sound somewhere around the rear axle, comes from under rear seat, in the middle area. The faster I go the louder the noise becomes. It stops when I am stopped. I thought it was the tires because they were worn. I bought four new michelin tires and the noise did not get any better at all. Any help is greatly appreciated. Thanks.

#16 of 20 AC noises by ben20433 Jun 20, 2009 (12:36 pm)
2002 Jetta GLC: Intermittent loud noise (with vibration on accelerator peddle) that appears to come from under the center of the dash. This happens only on warm days with AC on. If I turn AC off it goes away. When it happens the car loses power. Replies to this message: singh5513 (Jul 08, 2009 5:41 pm) adriaandev (Oct 15, 2009 9:24 am)

Replying to: ben20433 (Jun 20, 2009 12:36 pm) I beleive I have an answer for some of the related posts. I recently bought a 2009 jetta. Vibration noise comes at highway speed and comes and goes with the fan or when tailgaiting a truck or not. The vibration frequency does not change with engine speed or road speed. The amplitude changes with wind speed. It can be felt on the steering wheel and pedals.   First I thought it was wind vibration of the body screen below the engine .. I modified it and the vibration remained. With that body panel/protection off, I noted the AC fan and water cooling fan hood is very flimsy and vibrates exactly at the same natural frequency as I am experiencing. By now I am so sensitive to the noise that I can hear it at speeds as low as 35 to 40 mph. I tied back the fan hood temporarily and it changed the speed at which it starts. I am going to request that VW fix this as a warrentee item. It is clearly a design flaw.
#19 of 20 Jetta "squeal" at startup by bizineer Nov 01, 2009 (2:59 pm)
I recently bought a used 2002 Jetta (manual, 2.0, with A/C) with 144k miles. It has started making a short (2-3 seconds) squealing noise at engine startup. The noise seems to come from just to the driver's side of the engine compartment. It only happens at start up and the volume and duration of the noise do change randomly, but only slightly, The check engine light is on and it gives a code that indicates that there is a misfire in the 4th cylinder (it has been reset 3 times and each time comes back with the same code). I do not have maintenance records for the vehicle. Any suggestions?
#20 of 20 Noise under the dash on passenger side by santiael Nov 05, 2009 (12:38 pm)
I have a 2007 Jetta with just over 27,000 miles on it. Recently I started hearing a noise under the dashboard on the passenger side, kind of like a grinding noise, like a bad stepper motor sound. I hear the noise only for a few seconds when I first turn the car on, regardless of whether the engine is on or not. I also hear the noise when I push the air recirculation button on and off, as well as when I put the car in reverse. Any ideas?
