Volkswagen Touareg & Audi Q7 3.0 TDI Oil Change Guide
Routine oil and filter replacement is one of the most important maintenance services for the 3.0-liter CATA V6 turbo-diesel engine found in compatible Volkswagen Touareg TDI and Audi Q7 TDI models.
Using an engine oil with the correct Volkswagen approval is especially important because these vehicles combine turbocharger operation, direct diesel injection and emissions equipment such as a diesel particulate filter.
For compatible 2009–2012 CATA applications, the Volkswagen Touareg and Audi Q7 TDI 5W-30 Oil Change Kit combines 9 liters of Liqui Moly Top Tec 4200 5W-30 with an OE-quality Hengst oil filter.
Why the VW 507 00 Approval Matters
Oil viscosity alone does not determine whether an engine oil is suitable for a Volkswagen or Audi diesel engine. The required manufacturer approval is equally important.
Liqui Moly Top Tec 4200 New Generation 5W-30 carries the VW 507 00 approval for compatible diesel applications. It also meets the ACEA C3 specification and uses a low-SAPS formulation designed for vehicles equipped with modern exhaust-aftertreatment systems. Liqui Moly product specifications
Using an oil with the appropriate approval can help support:
- Proper turbocharger lubrication
- Reliable cold-start oil circulation
- Protection under high engine temperatures
- Reduced deposits inside the lubrication system
- Compatibility with diesel particulate filters
- Long-term engine cleanliness
Liqui Moly Top Tec 4200 5W-30
Liqui Moly Top Tec 4200 is formulated for modern gasoline and diesel engines requiring specifications such as VW 504 00 or VW 507 00.
The 5W rating supports oil circulation during cold starts, while the 30-grade operating viscosity provides stable lubrication after the engine reaches operating temperature.
The complete kit supplies 9 liters through one 5-liter container and four 1-liter bottles. This arrangement makes it easier to add oil gradually and accurately set the final level.
Hengst E73H D207 Oil Filter
Fresh engine oil should always be paired with a new oil filter during routine service.
The included Hengst E73H D207 is a cartridge-style filter that cross-references Volkswagen and Audi oil-filter number 057 115 561 M. It includes the applicable filter-housing seal.
The filter is designed for compatible 3.0-liter V6 applications, including the 2009–2012 Audi Q7 TDI and Volkswagen Touareg TDI.
Compatible Vehicles
| Year | Make | Model | Engine | Engine Code | Fuel |
|---|---|---|---|---|---|
| 2009–2012 | Audi | Q7 TDI | 3.0L V6 Turbo | CATA | Diesel |
| 2009–2010 | Volkswagen | Touareg TDI – 7L | 3.0L V6 Turbo | CATA | Diesel |
| 2011–2012 | Volkswagen | Touareg TDI – 7P | 3.0L V6 Turbo | CATA | Diesel |
Always confirm the engine code and filter number because other Q7 and Touareg configurations may require different components.
General Oil Change Procedure
- Bring the engine close to normal operating temperature.
- Park the vehicle on a level surface and switch off the engine.
- Raise and support the vehicle using approved lifting points.
- Remove the applicable lower engine cover.
- Position a suitable drain container beneath the oil pan.
- Remove the drain plug and allow the used oil to drain completely.
- Replace the oil-filter cartridge and filter-housing seal.
- Lubricate the new seal with a small amount of fresh engine oil.
- Reinstall the filter housing and drain plug using the manufacturer’s torque specifications.
- Add the correct quantity of Liqui Moly Top Tec 4200 5W-30 gradually.
- Start the engine and inspect the filter housing and drain plug for leaks.
- Allow the oil to settle and verify the final level using the vehicle’s specified procedure.
Never add all 9 liters without checking the oil level. The supplied quantity is intended to provide sufficient oil for the service, but the amount retained by the engine can vary.
Common Oil Service Mistakes
Choosing Oil by Viscosity Alone
Not every 5W-30 engine oil carries the VW 507 00 approval. Check both the viscosity and manufacturer approval before filling the engine.
Installing the Filter Seal Incorrectly
An incorrectly positioned filter-housing seal can cause leakage. Install the new seal in the correct groove and lubricate it with clean engine oil.
Overfilling the Engine
Adding too much oil can create lubrication and emissions-system problems. Fill gradually and confirm the final level.
Ignoring the Engine Code
The same vehicle model may have been sold with several engines. Confirm that the vehicle uses the CATA 3.0L V6 diesel engine before ordering service parts.
Reusing Old Sealing Components
Replace the applicable filter-housing seal whenever the oil filter is changed.
