Engine oil and filter change- B5 VW Passat TDI

Engine oil and filter change- B5 VW Passat TDI

    back to 1000q: B5.5 VW Passat TDI "how to" index


    Here are tips and DIY steps to change the engine oil on your VW Passat TDI (2004-2005).
    When the correct synthetic engine oil is used on your 2.0L BHW TDI engine the change interval with filter change is 10,000 miles. Note: 5w-40 engine oil designed for pumpe duse engines (VW 505.1 specificiation) works well in these engines but ultimately the oil you use is up to you. See 1000q: engine oil for pumpe duse to see some notes on why certain engine oils were specified for pumpe duse engines.

    You could use an oil extractor pump to suck the oil out through the dipstick but I prefer to get under the car. This lets you inspect the area and also drains the bottom of the pan better. It also gets more old oil out.

    17 or 18mm wrench

    Caution - some oil filters were manufactured with the "top" label on the bottom! When you remove the old filter, note how it fits. The new one should fit the same. It will not fit correctly upside down.

    DIY oil change procedure
    It's best to do an oil change on a lukewarm engine. The warm engine will let the engine oil flow out easily and it shouldn't be hot enough to scald you.

    Raise the front of the car securely. Rest the car on jack stands, chock the rear wheels, and make sure the front of the car is safe and stable before getting underneath. See the TOS Agreement for the full legal disclaimer. You can also rest the front wheels on wood blocks, see 1000q: wood blocks for more details.

    Remove the front splash pan. It's 5 fasteners + a 10mm nut on the bottom, 2 on each side. Do not mix the locations of the fasteners, see 1000q: splash shield fastener list for more details.

    Place the oil drain pan underneath the oil drain.

    Loosen the oil drain plug (circled in yellow below) by turning it counterclockwise. Caution - the oil drain plug is the 17 or 18mm hex (6 sided) bolt on the aluminum silvery pan under the engine. Do not remove the allen head plugs on the black pan under the transmission - that will drain the transmission! As it is removed, be prepared for a stream of warm oil to come out.

    Above the car, remove the 3x 10mm nuts holding the plastic engine cover. Loosen the oil filter cap by turning it counterclockwise, as highlighted below.

    Remove it - the oil filter is attached. Caution - some oil filters were manufactured with the "top" label on the bottom! When you remove the old filter, note how it fits - the new filter should be the same. It will not fit correctly upside down.

    You can use an oil extractor or vacuum pump to suck the old oil out of the filter housing. There's lots of oil there which will not be normally get drained.

    Remove the old o-rings and filter from the oil filter cap and put on the new ones. Lubricate them with oil. Note which side is "top" on the filter. It should fit the same as the one that was removed.

    The rest of installation is the reverse of removal. If there's a leak on the oil pan drain plug cut off the washer and replace, otherwise leave it alone. Use kitty litter or driveway stain absorber to soak up any spills. Do not dump used engine oil into the ground or water! Earth911.com can find your local waste drop off. Your local garage or auto parts store also accepts used engine oil.

    Vacuum oil extraction on a VW Passat TDI
    If you wish to use an oil extractor, this is acceptable and easier since you don't have to get under the engine to remove the splash pan. All you have to do is put the oil extractor tube into the oil pan through the dipstick and suck the oil out. The engine must be warm or else the cold oil will be too vicious. Once you think you're done, move the tube around to suck up the corners. Also insert the extractor through the oil filter housing down into the oil cooler to get it all out. TDILow3 made an oil extractor storage sleeve using some PVC piping to keep the tubing clean. Here is a .pdf showing the project:
