On every car sold (that I'm aware of) there is a sticker pasted, usually in the door jam of the driver's side, which states exactly what the car manufacturer suggests your tire pressure should be at. It will give a front/back pressure. This is what you should use and not what the pressure on the side of the tire says. The figure on the tire is the maximum ...

Depending on who asked you, and why, I would assume they were talking about the special socket needed to removed locking lug nuts from the car. On cars that have them, one of the 4 or 5 lug nuts/bolts will have a smooth outside and a special pattern on the inside that only a certain key will fit. The lock can typically be found near where your spare tire ...

Diagnosing noises when you're thousands of miles away isn't going to be easy, but here are a few tips to help you out: remove the serpentine belt and run the engine If the noise stops, you know that the noise source is something that is running off the serpentine. inspect the belt for loss of tension Loose belts are notorious for squealing spin the ...

CAUSE As it turns out, after further investigation a coin had fallen in to the lighter and caused a short circuit at some point in the past. FIX To fix it (at least in my case - the most common problem), you need a new 15A (blue) automotive fuse and a flat head screwdriver (or anything to prize off the fuse box cover). In my car the fuse box is located ...

The fact that you can hear some noise from the door with the inoperational lock is an indication that the wiring is fine. There is a good chance that the door lock actuator has gone bad and needs to be replaced.

tl;dr: it's really called a coolant flange. I had also never heard of a coolant flange but it turns out that it's a real part and, based on the video, it's a part that fails around 120K miles (which sounds reasonable for the age of your vehicle. An example of a coolant flange repair. Some examples of coolant flanges (which seem to be common for Audis and ...

Your Passat uses torque to yield bolts, so they must be replaced. The torque to yield bolts are considered "one and done". This is because during the torquing process, they are stretched beyond deformation, past their plasticity. If you try to use them again, they will fail. If you reuse them, not only will they fail, but you will most likely cause damage to ...

PROBLEM As you can see in the photo, on the lock actuator replacement part for my car door there is a plastic part (left) and a metal part (right). The two parts, metal and plastic, are supposed to move as one unit. If the unit is rotated anti-clockwise then the door lock will be in the locked position. If the door is rotated clockwise then the door would ...

In a manual tranmission car, the clutch is 'meshed' only when both sides of the clutch - the engine side and the wheel side - are running at the same speed. Downshifting Example I'll make up some numbers for an example: Say you're at 3rd gear, going 45 miles an hour and the engine is at 2.5k RPM. If you downshift while still going 45 miles an hour, the ...

In a car normal lug nuts or lug bolts in your case have some type of hex head. This can be easily removed with a lug wrench or a ratchet and socket. This also make wheels easy to steal. To counteract the theft there exist special lug bolts that have a non standard pattern. This pattern requires a key to covert the special pattern to a standard hex. This is ...

I don't know about longer (this is relative to the exact engine being served and the ignition type), but it is harder to start a cold engine. There are a couple of things going on with the engine when you go to start it when it's cold. The first of which is the oil is harder to push around, so uses more juice from the battery to get the engine going. When ...

If the boot is leaking, then it is the grease coming out and a lack of lubrication will cause the cv joint to fail. Depending on the design then it may be possible to fit a new outer cv joint or it may be a complete shaft. As for how long, that is the length of a piece of string type question...

Something else to be watch out for, if you filled the tire to 44 PSI while the weather is cold and the tire is cold from not being driven, as soon as it warms up, the tire warms up, and so does the air in it. For a temperature change of roughly 10 deg C the pressure will increase about 3 PSI. Which if you have filled up the tire to the max, already puts you ...

"Blipping" the throttle just means giving it a very short (half a second) stab raising the RPM for a short time. It creates smoother down shifts because it raises the RPM to where it's going to be after the shift so the synchros have less work to do.

If you dont hear any buzzing sound from the pump then. Check for a blown fuse. If the fuse is intact then remove the pump and take it to a mechanic to fix or replace.Also if possible check the wiring. Overfilling does not cause any problem as long as the pump is working. Fuse Location for VW Passat Note:Number 24 is the fuse for windscreen washer motor.

As the comment says, looking at the web site you posted there seems to be a couple of flavors of engine for your car. So unless we know the displacement (it would say 2.3L V6 for example) we can't say exactly for your car. There are 5 or 6 flavors listed for your car, from a 1.8L 4 cyl, to a 4.0L V8 ( would love to see how this is stuffed into a Passat lol). ...

The answer to the first bullet. The roll of the CV or constant velocity joint is to enable movement with independent suspension. As the geometry changes (when you hit a bump), the wheel moves up. If the axle were solid, this would be unable to happen. The CV joint allows for the movement of the suspension. I guess you could think of it like a swivel socket. ...

Sounds like a simple case of driving too fast in the rain. There's only so much water that tires can push out of the way, and the effectiveness drops as the tires wear, water depth increases, and speed increases.

Correct Tire Pressures As @Random832 mentioned in the comments, the information for my 2004 VW Passat B5 was not in the door jam of the drivers' side, but rather it was actually on the inside of my fuel filler lid. Here is what it looked like: As you can see, the pressure here varies for the approximate amount of weight that the car is carrying, but also ...

There is usually a fuse just for the cigarette lighter socket, this is the first thing you should check. You should be able to find it in one of the fuse boxes. Looks like there is a fuse box on both the driver's and passenger's side in the passenger compartment and different Passats have different fuse numbers, but it looks like you are looking for a ...

The heated mirrors have a restive heat strip spiraled around the back of the mirror. It works much like the defrost "wires" on a rear car window but since its a mirror, you can't see them. The MkIII Jetta didn't have a control for the heated mirrors - they were always on, and would fail more often than the switched ones on newer cars, but failure does ...

3 ways: Drive the vehicle and do both light braking from 25mph then hard braking from 55mph, if the brake pedal pulses up and down or the steering wheel shakes or vibrates, then you have at least one warped rotor. If stops are smooth and relatively noise free then go to #2 below. Pull the rotors and do a visual inspection, look for cracks (even small ones) ...

If your mechanic says 'Timing chains are for life and require no maintenance' then please find a new mechanic. There are loads of examples of timing chains that are designed for life but suffer from early failure of some sort whether its stretching, snapping, a tensioner or guide failing or anything else. Examples include: BMW N47 2.0D - Probably the most ...

The easiest way is to get wheels you know fit - i.e. ones specifically sold to fit a Passat ;) Otherwise you'll need something compatible - the key things are the PCD (bolt pattern), offset (ET) and centre bore (CB above). The bolt pattern is obvious, it's how many bolts you have (5) and how far apart they are (equally spaced around a 112mm diameter ...

Visual Inspection CABLE HOUSING/SHEATH You can follow the brake cable back to the rear of the car. I'm not sure if it goes to the right or left rear. In so doing you can see if it has any damage. A bad kink in it, torn cable housing (if you can see the actual cable in the housing due to damage....that's not good) Parking Break Mechanism The cable ...

If the system is either working fine or not at all then the likely failure is in the control gear for the system, the AC clutch would be my first port of call, you'll need an assistant: Open the engine bay and look for the AC compressor, it is one of the ancillaries at the side of the engine run by a serpentine belts. The compressor pulley has a clutch ...

I wouldn't risk it. If the water pump fails you can easily cook the engine, leading to no end of problems (failed head gasket, warped head, etc). The temperature gauge will only give you an accurate reading if the coolant is flowing through the engine - if it isn't you will end up with hot spots very quickly. A lot of modern cars have an ecu-controlled ...

Replace the bolts, this has been covered in detail on this site : here is one such post with lots of detail : "Always Replace" (torque-to-yield) Bolts

This sounds like temperature sensor problem. The ECU thinks the engine is always cold, and is trying to start a warm engine like it would start a cold engine. When you wait 30 minutes, the engine has had a chance to become slightly colder, and therefore, the cold engine start procedure works. Do note that the ECU temperature sensor can be different from the ...
