Jetta Noises



  • Yes. It turned out to be a bad recirculation flap motor (part # 1K0-907-511-C) under the dashboard on the passenger side. It was replaced and noise went away and still hasn't come back.
  • I just bought a 2006 Jetta. My first one and yes I hear that similiar noise at startup and then after about 30 seconds it goes away and the engine is humming. How much does it cost to replace that flap motor.
  • I don't know. I took mine to the dealer and the part was still covered under warranty.

    I hit a large pot hole in the road, after a few days i started hearing a loud noise. I can hear the noise on inside of car, but not outside. It sounds like i have a bad tire, had them replaced, did not help. Noise gets louder the faster i drive. Can anyone help me.

    My 2003 Jetta TDI makes noises when it is traveling on uneven roads such as streets with dips or pot holes. Thought it was suspension related, maybe shocks or struts, but that is not the case. Both my mechanic and body shop technician recognize that there is a problem, but don't know a solution. Is worse in warmer weather. It appears to need lubrication but I don't know where to lubricate.

    If by "noise", you mean sqeeky when going over dips on hot/humid days.... several folks have reported that lubricating or replacing the anti-swaybar bushings solved this noise.

    This problem with my 2006 VW Jetta has occurred once again and always after refueling. The first time this happened, the fuel guage showed in the red and the refuel light had just turned on. As I drive into the gas station, I hear a loud thudding in the back of the car like somebody was in the trunk. After stopping beside a pump and turning off the engine there is a loud pop. I refuel with regular unleaded and refill completely as I always do. As I restart, the engine "turns" but doesn't "catch" so that the engine remains turning. So I call a friend and he recommends I pump the gas pedal as the engine is 'turning'. It worked. He also said the thudding was probably my fuel pump. He also suggested I use a fuel additive. First can anybody explain the problem with the thudding and popping? Is it really the fuel pump and how long is a fuel pump supposed to last? And is using a fuel additive on every fill up safe for the car. 3 weeks has passed since then and after that time, I did not have the problem again until today. Again, after I refilled completely, I had to once again pump the pedal as the engine is turning. However, today there was no popping or thudding, and it has been 2 fillups since I used a fuel additive. CAN ANYBODY TELL ME WHY THE CAR IS DOING THIS? Is it the fuel pump? Is it clogged fuel injectors? Is it the starter coils, which they did just replace due to a recall?
  • i have a 2000 jetta 1.8 t that beeps when the temperature is hot outside. it stops as it cools off. it doesnt beep during the winter. strange? yes indeed, not even the pros at the local vw dealer could solve the issue. any thoughts?
  • Did you find out what was going on with your Jetta? Mine is doing the same thing, also a 2002.

    Squeel is most-likely the serpentine belt slipping until it warms up. Warm rubber tends to 'stick' to the pullies and stop slipping.

    see my last append about the squeel....

    Regarding the "misfire" code - OF COURSE it will keep coming back if you just reset the code and not fix the problem. What do you expect??

    A good way to isolate/fix a "misfire" code is to replace sparkplugs. Remove and clean the spark-plug wires and igniion coil.

    Worst case, you may need to REPLACE the spark-plug wires ... However, since the spark-plug wires for that engine cost over $100, it is worthwile to first try cleaning them and applying silicone grease to the boots.

    Very rarely, the ignition-coil itself may have a crack in it and cause misfires. When you remove it for cleaning, you can scrutinize it for cracks. If it is cracked, some people have reported having luck sealing the crack with RTV silicone.
  • Would you happen to know what the indicator light that shows what looks like a gas cap coming off means? I know thy the gas cap is on and not loose. Why would that be light be coming on?
  • bpeeblesbpeebles Posts: 4,085
    I was not aware that there is such an indicator on the Jetta.... What year is it?
    If you have misplaced your manual, they are available online.

    With that said... I know there is a diagnostic test that runs which tries to pump a slight pressure in the air in the gastank. If it cannot build pressure, it is assumed that the gascap is not sealed properly. Most cars will simply lite up the CEL when this test fails.
  • You're right! it's not one of the indicators that light up when the car does it's startup test. My car is a 2006 Jetta and the light is next to the center bolt (for lack of a better word) that holds the needle on the RPM dial. Anyway I always hear this stretching noise at startup andsometimes this kind of pumping noise while I drive after coming from a cold start.

    Hello, my girlfriend's 2006 Rabbit (2.5 - manual) is having the same problem (she sometimes hears a knocking and it won't restart after re-fueling until she pumps the gas).

    Did you ever find out what was causing your problem?
  • Hi, I hear the same thudding noise in the rear of my Jetta and would like to know if you have an answer to this problem...

    my daughter has a 2001 v20 turbo jetta that when idleing makes a strange gurgling noise in the air-intake. It was fitted with a K&N intake before we bought it. I replace some of the air lines that come from the top end of the engine. when i got the broken pieces out of the fitting noticed a pasty, oilly, and watery. Tried to blow all of the water out with compressor, but air-intake sounds like it is sucking water through a straw with a hole in it.

    any help would be greatly appreciated

    I am not so sure that VW offered a 2.0L turbocharged engine in 2001. I believe it was a 1.8L turbo. (Actually an Audi engine)

    The gurgling you hear may be oil sitting in the base of the intercooler. The oil usually gets there from leaking oil-seal on the turbocharger. A small amount of oil in the intercooler is normal.

    VWs have a "Cold-Air-Intake" from the factory and adding something else is just a waste of money. The factory air-filter is MORE than adequate for the engine. Especially a turbocharged engine where the air is FORCED into the engine.

    K&N intake filters on a VW are bad news. The oil from the filter is KNOWN to contaminate the MAF (Mass AirFlow) sensor. You have been warned.
    (Youngsters add CAI to turbocharged engine so they can hear the whine of the compressor.)
