The Haldex 111358 is the OEM oil filter for the 4th generation Haldex AWD coupling, used across VW Group vehicles from approximately 2008 onwards. If your Audi, VW, Seat, or Skoda runs a Gen4 Haldex unit, this is the filter your system needs. The part number 111358 and its synonym 2003085 both refer to the same genuine BorgWarner component, so either reference confirms you have the right part.
Compatible vehicles include:
- Audi TT, TTS, and TT RS (Quattro, 2008 onwards)
- Audi A3 8P with Quattro
- VW Golf R (4Motion, 2008–2014)
- VW Tiguan, Passat, and VW CC (4Motion)
- Seat and Skoda models equipped with the Gen4 Haldex coupling
What does the Haldex 111358 filter kit contain?
The 111358 kit is a complete service set, not just a filter element. Buying only the filter and reusing the old cap is one of the most common and costly mistakes mechanics make, because the cap’s internal oil channels accumulate sludge over time and restrict fluid flow even when a fresh filter is fitted.
The full kit contains:
- Filter element
- Filter cap
- Rubber seals
- Nylon retainer
- Fixing screws
- Cover
Genuine filters carry precise dimensions: a 9.15 cm outer diameter and an M16x1.5 thread size, both critical for correct fitment in the Gen4 unit. Deviate from those specs and the filter simply will not seat properly.
| Specification | Detail |
|---|---|
| OEM part numbers | 111358 / 2003085 |
| Outer diameter | 9.15 cm |
| Thread size | M16x1.5 |
| Compatible AWD system | 4th generation Haldex |
| Manufacturer | BorgWarner |
| Kit contents | Filter, cap, seals, retainer, screws, cover |
Febi Bilstein also produces a compatible aftermarket alternative for this application, though OEM BorgWarner kits remain the benchmark for fitment accuracy and longevity.
Which vehicles use the 111358 Haldex filter?
The Gen4 Haldex compatibility covers a broad range of VW Group AWD models built from 2008 onwards. The coupling appears under the Quattro badge on Audi models and as 4Motion on VW, Seat, and Skoda platforms.
Confirmed applications include:
- Audi: TT, TTS, TT RS, A3 8P (all Quattro variants)
- VW: Golf R, Tiguan, Passat, CC (all 4Motion variants)
- Seat: AWD models with Gen4 Haldex coupling
- Skoda: AWD models with Gen4 Haldex coupling
To verify fitment precisely, cross-reference your vehicle’s VIN against the OEM part number 111358 or 2003085. Your vehicle’s build date matters too: the Gen4 system was phased in from mid-2008, so early 2008 builds may carry the Gen3 unit instead.
How often should you replace the Haldex 111358 filter?
The standard recommended service interval for the Haldex filter and fluid is every forty thousand miles. Miss that interval and the filter traps enough debris to degrade fluid lubricity, which puts real stress on the clutch plates inside the coupling.
For harder use, detailed maintenance techniques from the Auto Detailing Blog suggest that interval shortens considerably. Professional technicians recommend servicing at 20,000–30,000 miles when the vehicle sees track days, heavy towing, or frequent stop-start urban driving. The filter traps debris that degrades fluid quality faster under those conditions.
Key maintenance points:
- Replace the full kit every 40,000 miles under normal use
- Shorten to 20,000–30,000 miles for track, towing, or urban stop-start use
- Always use OEM G 055 175 A2 fluid alongside the filter replacement
- Never reuse the old cap; replace the complete kit every time
Pro Tip: Always replace the cap alongside the filter element. The cap’s internal channels clog with sludge independently of the filter, and a blocked cap restricts oil flow even with a brand-new filter fitted.

- Specialist online platforms: Verify OEM part numbers (111358 or 2003085) before purchasing
Pricing for a complete OEM kit from a UK specialist typically sits below main-dealer rates while delivering the same BorgWarner-sourced component. For a broader look at AWD service kits, Haldexparts lists the full range alongside compatible oils and pumps.
How to avoid common pitfalls when buying or fitting the filter kit
The single biggest purchasing mistake is ordering just the filter element. Without the cap, seals, and screws, you cannot complete a proper service, and reusing worn seals risks an oil leak at the filter housing. Always confirm the listing explicitly states “full kit” and cross-check the part number.
During fitting, the most common error is overtightening the cap. The M16x1.5 thread is fine-pitched and strips easily if torqued beyond spec. Use a torque wrench and follow the manufacturer’s figure. Skipping the torque step and tightening by feel is how caps crack.
Step-by-step Haldex 111358 filter replacement
- Lift and support the vehicle safely; locate the Haldex unit on the rear axle.
- Place a drain tray beneath the unit and remove the drain plug to drain the old fluid fully.
- Unscrew the filter cap using the correct socket; discard the old cap, filter, and seals.
- Clean the filter housing bore thoroughly before fitting the new components.
- Fit the new rubber seals dry, without lubricant, to avoid swelling.
- Insert the new filter element, then thread the new cap by hand before torquing to spec.
- Refit the drain plug, refill with OEM G 055 175 A2 fluid to the correct level, and check for leaks.
Pro Tip: Refer to the AWD servicing guide for torque figures and fluid volumes specific to your model before starting the job.
How to spot a counterfeit Haldex filter
Counterfeit Gen4 filters circulate on general marketplace platforms, and the consequences of fitting one go beyond poor filtration. A fake cap with incorrect channel geometry starves the clutch pack of oil, causing premature wear that costs far more to fix than the saving on the part.
Genuine BorgWarner kits carry the BorgWarner branding on the packaging and the part number 111358 or 2003085 printed clearly on the filter cap. If the seller cannot confirm either number, or if the packaging looks inconsistent, walk away. Buying directly from an authorised distributor like Haldexparts removes the guesswork entirely, since every kit ships as a verified OEM unit.
Key takeaways
The Haldex 111358 is the correct OEM filter for 4th generation VW Group AWD systems, and replacing the complete kit every 40,000 miles protects the clutch pack and preserves AWD reliability.

|---|---|
| OEM part numbers | 111358 and 2003085 are synonymous; both confirm a genuine BorgWarner Gen4 filter kit. |
| Service interval | Replace filter and fluid every 40,000 miles; reduce to 20,000–30,000 miles for track, urban, or towing conditions. |
| Always replace the full kit | Reusing the old cap risks oil channel blockage and AWD system damage. |
| Fitment specs | 9.15 cm outer diameter and M16x1.5 thread; deviating from these causes incorrect seating. |
