How to Install a Blow Off Valve on a Passat

1. Park the Passat in your driveway and pull the emergency brake up. Pull the hood release latch, then turn the Passat off. Prop the hood up and disconnect the black cable from the car battery to protect yourself from electrical shorts. Put drop cloths on the edges of the engine bay to protect the paint.
2. Locate the turbocharger downpipe; the Passat's blow off valve is attached to the side of the pipe. Pull the vacuum line top from the top of the blow off valve by hand. Unscrew the O-ring clamp that secures the bottom of the valve to the downpipe port. Pull the old blow off valve off and place it to the side.
3. Plug the new blow off valve into the port on the downpipe. Screw the O-ring clamp onto the bottom of the blow off valve until it is tight and will not budge. Plug the vacuum line in on the top of the blow off valve. Reconnect the black wire to the car battery and shut the Passat's hood.
4. Turn the Passat on and take it for a test drive. If the Passat blow off valve is installed correctly, the engine speed will drop suddenly once you exit the turbo power band. If the engine speed stays elevated after fast driving, then the blow off valve is not working right. The vacuum line may have come off or the blow off valve spring may be broken.

How to Lease Audi Cars

Getting into a new Audi lease
1. Get out there and touch what you want. Start by going to your local dealer and take a look at the specific model you are interested in. Try to see all the different colors in person on the vehicle. Take a look at the different trim levels and what you will be getting with certain packages and options. Sometimes one particular feature that you really want is only available with an upgraded package. Xenon headlights are a good example on the 2009 and newer Audi A4s. You can only get the Xenon headlight package on the Premium Plus model, which adds a few other features that you may not be interested in paying for and don't really need.
2. Do your financial homework. Find out what lease specials are running in your area. AudiUSA.com will keep you up to date with available lease offers. You also want to find out the money factor and residual value of your new Audi. A money factor will usually be in a decimal point format (.00089 or .00125). Take that number and multiply it by 2400 to find out what the actual interest is that you will be paying on your new lease. The base residual value will usually be for 15,000 miles per year. Most banks add 2 percent to the residual value for a 12,000-mile-per-year lease or 3 percent for 10,000 miles. Not all banks follow this formula, so ask your salesperson which financial institution your Audi will be leased through
3. Now that you know what car you want and what lease specials are running, find out how much you should be buying the vehicle for. Edmunds.com is a great tool for finding out what a vehicle is selling for in your market. They will tell you what other people in your area are paying for the same model vehicle. They will also give you a breakdown of MSRP (Manufactures Suggested Retail Price) and the Invoice (what the dealer pays for the vehicle) price on the vehicle.
4. Jump online and send out a few requests for lease quotes from different dealerships in your area. You can have them tailor the lease to meet your needs, such as you need to put less money down at lease signing, you need more miles per year for the lease, or you need to have the lease shorter or longer than what is being offered.
