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.
#30 of 45 Post-Refueling Problem
Jul 20, 2010 (6:30 pm)
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?

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.
