OVERVIEW
Filter the oil in the assigned six-speed automatic transmission
09G-325-429-E is the Genuine VW/Audi oil strainer for the specified automatic transmission applications. The filter sits within the transmission oil circuit and captures contaminants before they circulate through sensitive hydraulic components.
Correct filter selection depends on the actual gearbox code and original filter design. Several transmissions can be fitted to the same vehicle model, and filters with nearby part-number suffixes are not automatically interchangeable.
Technical details
- Complete factory number: 09G-325-429-E.
- Factory specification: automatic transmission oil strainer, complete revision E.
- Design: molded filter housing with the original mounting tabs and oil-pickup connection.
- Quantity supplied: one individual transmission oil filter.
This is a dry replacement filter. Transmission fluid, pan gasket, filter-neck seal, pan, magnets and installation hardware are separate unless expressly supplied with a verified factory service pack. Identify the seals required for the actual gearbox before beginning service.
Common reasons to replace
- The transmission-specific service procedure calls for a replacement filter.
- A damaged pickup housing or attachment prevents correct installation.
- Contamination found during diagnosis requires filter renewal and correction of the underlying fault.
- The original filter is restricted or damaged, as established during inspection.
Identify the transmission code and examine the removed fluid, pan and magnets. Excess metal or friction material can indicate an internal fault requiring further diagnosis. A new filter alone will not repair worn clutch packs, a faulty valve body or an incorrect fluid level.
Vehicle fitment
Use the table with the gearbox identification, not engine size alone. PPU/QNQ applications are distinct from QWJ/SCV, DSG, manual and other transmission variants.

Installation guidance
Follow the exact gearbox procedure for pan removal, filter mounting and seal replacement. Keep the oil circuit clean, renew the specified sealing parts and use only the approved transmission fluid. Follow the prescribed temperature-dependent fill and level-setting process.
Check for leaks, verify the fluid level at the specified temperature and complete the required gear-selection and road-test checks. Investigate any remaining shifting faults before returning the vehicle to service.
