2003 Volkswagen Jetta squeaking noise!

My 2003 Volkswagen Jetta (gas engine if that matters) has been squeaking almost nonstop. I haven't changed anything since I've gotten it which was not that long ago, but I don't know the history of work it has gotten. It has about 102k on it right now. The squeaking isn't the brakes, that much I know. It's coming from the front passenger side. I'm wondering if it's a belt, but I really have no clue. It doesn't seem to be effecting the performance of the car (at least not yet, knock on wood), The last time I had something that sounded like this on a car it was the serpentine belt. I can't hear the squeaking when it's at a stop, or going below 20 mph, but it gets louder the faster it goes.

I know this isn't much to go on but any suggestions are appreciated!

If you can't hear it when it is stopped, then the serpentine belt cannot be the problem. My 2002 Jetta has squeaks in the suspension bushings. Spraying silicone lube on them temporarily stops the squeaking.

As you probably know squeaking could be alot of things, but the most common noise, that would not effect performance, would be serpentine belts. You can buy a can of belt dressing at Autozone, that you spray on the inside, the contact side, of the belt. If it is the belt, this should help. If it's been a long time since replaced you may want to replace belt. Alot of those belts will break after being worn out, but the better quality belts may not break, but they will make a horrendous squealing noise. If it's not the belt, you'd have to have someone look at it to troubleshoot. Good luck.

My 2003 Volkswagen jetta wolfburg edition has the check engine light on and its acceleration is horrible, and the car shakes alot wile accelerating..what could be my problem

Bigsis, take your car to Autozone to get the engine light scaned. The light comes on when the computer picks up a problem with the vehicle. They scan it for free, tell you the code and what it means, and tells you what parts you need. This way, you know what to do and it doesn't cost anything to find out. If you need anything else, we are here to help in anyway. Thank you very much for choosing FixYa and Happy Valentines Day.

I need to know when the 2003 jetta needs a tune-up, i've gotten 3 answers from 3 different places, when are they do for spark plugs and such?

The answer for everything depends. However, there are recommended intervals. Oil changes can be done btween 3,000 & 5,000 depending on how dirty is gets, but always do it within 6 months because it breaks down even sitting over time. Plugs can go up to 30,000. How you drive and the quality of the plugs will matter here. Best thing to do is to check the most accessable plug every 10,000 miles or so for wear, but replace them all together. You don't want old plugs...they are cheap and easy to install, but if they fail or break, it could be bad news.
Coolant is recommended to be flushed every two years, as is the brake fluid, but the brake fluid can go a very long time...5 to 10 years just make sure it is full. Replace wheel bearings when they squeak or leak oil. Tranny fluid can also go many years if it is working properly. Just look for leaks in the pan gasket. The drive belts should be replaced when they look worn, which could be 30,000. The timing belt should be good for 60,000 to 100,000, But if it goes it will take your engine with it. So, make sure it is good to go. Get a repair manual to help you inspect the car for worn parts.

I got an 96 jetta and its has a burning smell and makes a sqeeking nosie

Could be a belt that is too loose.

Is the smell like burning rubber?

Is the squeak coming from the engine compartment?

Does the squeak go away when you rev the engine?

If yes to these questions it sounds like a loose belt. You would need to replace it.

2003 Jetta TDI vibrates above 35 speed

With 180k I would change the engine mounts. They are about the only thing that would dampen engine vibration and noise (assuming that the engine is running ok). There is likely one or all weak or broken. Normally when you have a vibration at speed then it is going to be driveline or wheel balance.
