A few problems you would expect with a used Volkswagen Passat are problems with the fuel system, braking system, and engine.
That's the starter relay. Replace the starter.
if you don't mind scratching the paint work i would use a sledge hammer or 200g of TNT
it would over heat
No it does not require 2 batteries unless you have some aftermarket stuff added to your car. But you would have to have a lot of stuff added to overload it.
There are many different car models manufactured by the car company Volkswagen. Some examples of these models would be the Beetle, the Tiguan, and the Passat.
Fuel, and brake problems.
The Volkswagen Quantum is a foreign made car. Volkswagen is one of the leading German automotive manufacturers and they are the makers of the Quantum. Most people, however, would not recognize the vehicle as the Quantum, but rather under the name it is known by in the United States, which is the Passat. The name Quantum is one of several that have been applied to various models of the Passat throughout its six design generations, which began in 1973.
You haven't stated any problems. What same problems are these?
The 2000 to 2006 Volkswagens have had electrical recalls on them and are nitorious for having lighting problems. Best bet would be to call your dealerships and find out if they can fix it for free from the factory or sell it.
You would need to take off the door panel in order to remove it. I've included an auto repair video in "related links" down below that will show you exactly what needs to be done to replace it on your 2000 Volkswagen Passat. Hope this helps you out.
I assume you want to drain the oil out. The sump plug is under the engine - about in the middle. You would need to remove the underbody covers (10 mins) and then you will see it.
An oil cooler extends the life of an engine by specifically keeping the oil 'cooler' that what the regular cooling system can do (which is designed to cool the entire engine). If your car has some SEEPAGE around the cooler and/or lines that is not the end of the world; but if it LEAKS repair it. Since it is external to the engine I would not expect it to be a major repair.
