It's usually possible to restore any car as long as you have the appropriate knowledge, tools, money and time to do so. As others have mentioned, you may want to consider if it's worth it to fix a car that wouldn't be worth much even if it is running. I'm currently restoring a 1976 Fiat 124 that hadn't ran in around 10 years, sitting outside in the rain ...

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, ...

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

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.

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 ...

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 ...

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 ...

When was the last time the transmission's gear oil was changed? If it has been a while (or never), get it changed. Check your manual for the recommended interval, this is one of the fluids that is often overlooked. If it has never been done on a 2003, it needs to be done.

Personally I wouldn't be all that concerned unless the oil leak was large. One simple check for the state of health of the engine would be to take the car to an independent mechanic and have a compression test done. It won't catch everything that could be wrong with the engine, but if the compression test comes out OK, it can provide you a bit more peace ...

We have a Mk4 TDI Jetta that makes a sound after startup that might be described as a sneeze. I'm fairly confident that it's the starter motor's overrun clutch. As soon as the engine "starts," it begins turning faster than the starter can turn. For this reason, starters have a one-way clutch, called an overrun or sprag clutch. This permits the starter to ...

The chunks taken out are not affecting the integrity of the tire. Since there isn't any structural damage to the tire you should be fine. If you feel some vibrations in the steering wheel after the wheel encountered the curb it might be worth considering having that wheel rebalanced but I can tell you from experience that this is probably a non-concern.

As a vehicle technician for BMW I can assure that it is good for your engine to get rid of EGR. EGR systems are there to improve the exhaust gas quality and slightly win a few miles on a tank (in theory). What really happens is quite different. Your oil will become polluted quicker, your manifold / intake will get clogged by excessive amounts of soot and ...

I took my car to a different VW shop (not the dealership) and they fixed the problem for $160, but if I'd known the solution was just to solder the wires directly together, I could have fixed it myself. I did however, learn what the problem was thanks to them and I'll share the solution here. VW apparently knows about this issue and supposedly offers special ...

I had to deal with this problem some years ago on a VW. What I noticed is that the fusible link ran slack, causing the connection to arc and as a result burnt out the plastic housing below. I couldn't get a fuse box so I by passed the burnt area, had a link fabricated and secured it with a bolt and nut.
