Check the A/C drains are not blocked. The A/C condensates moisture from the air at the evaporator behind the dashboard. If the drains are blocked you will have a pool of water there ready to evaporate. The moisture will go up through the vents and condensate on the front windscreen. You will need to look under the car approximately under the dashboard. ...

That spring can rotate and rip out the tire - catastrophic loss when entering a bend could mean driver, occupants, other drivers, and/or bystanders could be singing with the angels... Ground the car instantly, it is not safe.

I restored a 1981 Mk1 Golf some years ago. It was an abandoned project and came with the engine in the boot, no interior and no front wings. Total cost to put back on the road was around £550 (GBP) around 8 years ago and total effort was around two to three months of working on it evenings and weekend at a fairly relaxed pace. Without more details it's ...

There are several different ways a manufacturer can detune an engine: Mechanically: Cam profile can be changed. For instance, reducing the lift from one cam to another will not allow as much air to flow into the cylinders. The end result, not as much volumetric efficiency (VE) and not as much power output. Create the engine with not as much static ...

Because you rarely use it, reducing its size and weight is an effective method for cutting down costs. It also saves space and makes packaging easier for the engineers. The cost aspect is also the reason for the spare being being a steel one instead of the more expensive alloy.

Do all cars that come factory fitted with alloys follow this rule? No, there are three basic options that I see all the time. An Emergency wheel - Will get you to the next tire shop or gas station. Has a speed limit of 55/mph and is smaller than normal. Also has a limited range. Usually 50 miles or so. There will be a label on the tire. Used to cut costs, ...

I think the point everyone else (and you) are missing here is if the weather is cold enough the temperature of the windscreen is below the dew point, your breath has enough moisture in it to do exactly what you're talking about. If the windscreen is below freezing, then your breath will first condensate there and then freeze. This lends perfectly well with ...

My biggest concern with issues like this is causing additional damage since the spring is no longer being supported the way it was designed to be. Also, the rear suspension is (obviously) compromised, handling is going to be affected. My recommendation is to park it until it can be fixed.

If you can't find the source of the moisture, you can use a work around. You say there isn't a problem if you leave the windows open a little to ventilate the car, but it lets in the rain. A solution to that is to fit wind deflectors. Although intended to deflect wind, you can leave the windows open an inch without rain getting in. The stick-on kind aren't ...

tl;dr: This procedure checks the oil "reserve" remaining in the pan after all moving parts are lubricated. This procedure is purely vehicle dependent. For example, on my car, I'm supposed to check the oil when the engine is cold. In asking you to check when the engine is hot, the oil will not be pooled in the oil pan. Instead, it will have been fully ...

I have both a 2004 Bora TDI (Jetta Mk4 in the US) and a 2012 Mk6 TDI Golf. When either of these cars requires it's warm up system, it will automatically switch it on for the time it needs. This is signified by the glow plug light illumination on the dashboard: Once it's up to the temperature it requires, the light goes out and the car can be started. I ...

The recall is not to remove the cheating logic; it is to actually make the engines meet emissions requirements so they do not violate the law any more. From Autoblog's initial article on the scandal: Volkswagen intentionally installed software in nearly a half-million diesel vehicles that helped the cars evade substandard results on emissions tests, the ...

If it is a 21W/5W bulb, then it has 2 filaments of different brightness. The 5W filament is for the side/tail light for night driving. The 21W filament is for bright illumination when you press the brake pedal. Image copied from ToolStation

The basic issue from a mechanical point of view is that the spring (not the shock!) is what supports the weight of that corner of the car. Clearly, with a piece missing, it is not doing that as it was designed to. If the car "bounces" while being driven, the broken spring may end up further out of position and not carrying any load at all. Personally I ...

It is the sound of the fuel pump priming and pressurizing the fuel lines, which is absolutely normal. VW likes to use the opening of the driver door to trigger fuel rail pressurization. In fact, one could use the absence of the sound of the fuel pump as a tell-tale sign that the fuel pump relay is not functioning properly. As @Paulster2 points out, either ...

As I understand it, there was a fundamental redesign in the cars from around 2002 onwards. Unfortunately that doesn't help you but I wonder if it is possible to retrofit the later model fuse box. Thank you for the picture, this has cleared things up. The fuse that has melted in your unit is S177 which is wired to the alternator. Apparently as the cable ...

Judging from the lights and body shapes I would say it looks like a 2015 Volkswagen Touareg.

You say that when you close the car, the air inside is dry. This might be the case, but cold air can hold significantly less water vapour than warm air. That is, the same air which was "dry" when you have closed the warm car will become oversaturated with water once it gets cold. And this extra moisture will condensate on those parts of your car which cool ...

This sounds like a problem with the coolant temperature sensor. Don't worry - replacement is cheap and can be done easily by yourself or a friend who worked on cars before. Cause Cold engines need more fuel to start than warm engines. This is due to the fact that a part of the vaporized fuel condenses at the cold cylinder wall inside each cylinder. This ...

It's a custom-wrapped VW Touareg. It looks like it belongs to an employee at Vehicle Wraps, a custom-wrap shop in Brisbane. There is a gallery on their Facebook page documenting the process and the gallery description reads: Bape no more we have wrapped the Touareg to match my Moth Sailing Boat It's not clear what year the model is, but the pictures ...

Yes it can run again, but is it worth it. Edmunds show a poor condition 1992 as worth about $650, where as a very good condition is around $2000. With your posting that it has rust above the wheel wells (not knowing how bad that is) it would likely need a respray after patching the metal. If your a do it yourself person cost can be fairly low but to to have ...

I highly recommend having the tires replaced. Even if physical deformation/damage is not evident from a visual inspection, there could be damage to the internal structure of the tire, like the steel belts. A blow-out at high speed would endanger yourself and those around you.

No you cannot safely tow the Jetta as you'll exceed the towing capacity of your Outback. The Outback can tow (depending on the options) between 2,700-3000lbs. The weight of the Jetta by itself is between 2,892-3292lbs. When calculating the towed weight, you need to include any other thing which you may be putting into your Outback, such as people or things. ...

Generally, these systems don't activate until the engine is warm, so you probably won't see it for the first 5-10 minutes of your journey - of course it largely depends on the nature of your journey as to whether that's useful or not, plus, as Solar Mike says, what you consider useful. For example, if your half-hour journey is 20 minutes pottering through ...

I read on a forum that the issue could be down to certain earth wires. When depressing the clutch pedal, you may be earthing a electrical line going to the sound system which in turn stops the music. There are various earths located in the engine bay. Check around the inner wings etc and make sure all of them are tight.

The engine will be fine - cars are designed to work in all conditions anywhere in the world. VW has a testing center that can theoretically test their cars and engines to work from -40 to 150C (saves on flying development cars to Finland and the Sahara) There will be some differences in the car trim levels; for example, cars in hot countries probably wouldn'...

I cannot tell you directly if the bolts you are using are Torque to Yield (TTY or T2Y) bolts, but if Bently says to replace them, you bet I'd do it. What are three bolts in comparison to the well being of your family and yourself, not to mention those around you should any of these bolts fail? As for T2Y bolts, here is what Fel-Pro says about them: T-T-Y ...

Don't know much about detuning gasoline engines, but in diesels one way that it is done is by using smaller injectors which deliver less fuel. Since a diesel engine is designed to run with "excess" air, restricting fuel delivery is a simple and flexible way to manage power output.

You didn't mention which engine is in your Jetta, but the Mk IV VWs, especially the VR6 engine, are known to have brittle ignition coil housings that crack and admit water, which leads to misfires. After the engine has run for a while, it burns off this moisture and it starts running fine again. Some VWs were subject to a recall to fix this issue. Based on ...
