VW Touareg Front Differential Fluid Change Interval
When should you change your VW Touareg front differential gear oil? We recommend changing the fluid around 80,000-90,000 miles. However, this can change depending on your driving style. If the vehicle sees spirited driving, you can service the front differential fluid as early as 50,000-70,000 miles. Abiding by these recommended differential fluid change intervals can eliminate and minimize front axle differential issues.
Why Should VW Touareg Front Differential Fluid Be Changed?
Your front differential has many internal moving components. This includes bearings, pinion gears and crown gears. These internal components rely solely on the diff fluids lubrication film strength for protection and longevity. Through use the diff fluid experiences excessive shear loads and various heat cycles. In time these heat cycles and excessive loads deplete the lubricating properties and film strength of the differential fluid. Continued use of old differential fluid will result in differential bearing, pinion gear wear and failure. Therefore, having regular front differential fluid changes is important. Changing the front differential fluid as regular routine maintenance will greatly extend the life of the front differential, minimize driveline noises due to wear, and ensure the bearings and gears receive reliable clean lubrication.

- 3/8 or 1/2 Inch Racket (dependent on bit socket)
- 3/8 or 1/2 Inch Extensions (dependent on bit socket)
- Oil Drain Pan Container
- Fluid Pump Tool (Optional - Its always easier with a pump and a flexible hose. Keep in mind the RAVENOL bottles have a built-in flex hose in the cap and can work for most applications. Possible fluid pump solutions are SKU part numbers J91001 or T2A0129.)
Disclaimer: Blauparts recommend having a factory trained A.S.E. certified VW mechanic perform vehicle maintenance. Always refer to the owner's manual and factory service manual for Audi axle differential fluid changing procedures. Always wear protective gloves and wear safety glasses when handling fluids and oils.
Step-by-Step VW Touareg Front Differential Fluid Change Instructions
How To Step 1
Since the front VW Touareg differential fluid gear oil is thicker it is best to get the differential fluid warm before draining it. This can be done by taking your car for a quick 10-15 minute drive. This will allow the front differential fluid viscosity to get thinner and flow more easily from the front differential when drained.
How To Step 2
Lift the vehicle using an approved automotive hoist or a floor jack and jacks stands so that the vehicle is in a perfectly level position. To confirm you are lifting the vehicle correctly refer to your factory owner’s manual for the proper vehicle lift point locations and procedures. The vehicle needs to be in a level position to confirm the correct transmission fluid level when refilling. If the vehicle is not level this can cause the automatic transmission fluid level to be incorrect and could cause transmission damage.
Important Note: Lifting the VW Touareg with a floor jack, jack stands or by an approved automotive hoist isn't necessarily required when changing the front axle differential fluid. The VW Touareg should have enough ground clearance in order to access and remove the lower protective splash pan and gain access to the front axle differential area. If you do desire to lift the vehicle for more working area under the vehicle, please proceed as follows. Confirm you are using an approved automotive lift or jack stands. Confirm you are lifting the vehicle correctly by refering to your factory owner’s manual for the proper vehicle lift point locations and procedures.
How To Step 3
Remove the under engine protective splash pan and place it off to the side. Keep in mind this is a 2-piece splash pan. First locating and remove all T-25 torx bit splash pan mounting screws. Next begin to remove the 10mm splash pan mounting bolts leaving one or two bolts hand threaded on the rear area of the splash pan. These last one or two mounting bolts remaining will allow you to support the pans with one hand and then hand loosen the last one or two bolts by hand minimizing the splash pan from falling on you.
It's also good to remove the rear portion of the splash pan first and then the front splash pan. The front portion of the two-piece pan can be tipped down and then pulled back from the front of the vehicle for easiest removal. (Image 1, 2 & 3)
How To Step 4
Locate, loosen (Counterclockwise), and remove the 8mm hex bit front differential fluid fill plug. This is located on the front side of the VW Touareg front differential. It is always best to confirm the fill plug can be removed before draining the differential fluid. This will confirm you will have a way to refill the VW Touareg differential with fluid incase the fill plug is seized or can’t be removed. (Image 4 & 5)
How To Step 5
Locate the 8mm hex bit front differential fluid drain plug on the bottom center area of the differential. Loosen, and remove the front VW Touareg differential fluid drain plug and allowing the old dirty differential fluid to thoroughly drain into a drain pan container. (Image 6, 7 & 8)
How To Step 6
Once the old VW Touareg differential fluid has been drained use a clean rag to clean the drain plug and excess gear oil from around the drain plug area on the differential. Re-install the differential drain plug. Using a torque wrench torque the drain plug to 26 ft-lb. (Image 9)
How To Step 7
Using the J1C1109 front VW Touareg differential fluid, begin filling the front differential through the fill port on the front side of the differential. Fill the differential with fluid until you see the differential fluid flow from the fill port. Make sure you have your drain pan container handy in order to catch the flow of fluid. Once you see the fluid flow in a heavy stream from the fill port the front differential fluid level is correct. This step should always be done with the vehicle and differential in a 100% level in order to confirm the proper fluid level. This step should never be done with the vehicle not level.
Once the fluid level has been confirmed I like to wait 10 minutes or so in order to allow any air pockets to leave the front axle differential. I Also like to rotate the axles several times. Many times, this will allow 1 or 2 more pumps (small amount) of differential fluid to still be added. For the front differential fluid capacity see the above listed capacities. (Image 10 & 11)
How To Step 9
Once the differential fluid level has been confirmed you can re-install the front VW Touareg differential fluid fill plug and torque it to 26 ft-lb. (Image 12)
How To Step 10
Use a rag to clean and remove all excess differential fluid from the front axle differential. The differential should be completely cleaned of all fluid. This will later help you to inspect and confirm that the differential does not have any leaks. (Image 13)
How To Step 11
After confirming you don’t have any VW Touareg differential leaks reinstall the under engine protective splash pan. First, line up and mount the front side of the splash pan leaving the rear mounting hardware off. Install the rear section of the slash pan by mounting the rear of it first and then lastly tipping up both splash pan pieces to the center, installing the mounting hardware. Protective splash pan mounting hardware: T-25 torx bit screws, 10mm hex head mounting bolts. (Image 1, 2 & 3)
How To Step 12
If you lifted the vehicle with an approved automotive hoist or floor jack and jack stands you can lower the vehicle as highlighted and referenced in your factory owner’s manual. Confirm the correct vehicle lift point locations and procedures as highlighted in your factory owner's manual.
How To Step 13
Once you have the vehicle on the ground you can take the car for a simple 5-10 minute test drive look at the front differential and confirm you do not have any leaks coming from the differential drain plug.
How to Step 14
Dispose of your old front axle differential fluid responsibly by taking it to a certified recycling collection center.
Side Note: It is good to note in your records the current mileage at the time of your front axle differential fluid change, as well as, when you might want to change it next. We also recommend keeping detailed service records to keep track of your vehicle's true condition. Keeping good vehicle maintenance records can help improve your vehicle resale value.
