As an independent Vw service garage with over 23 years of hands-on experience, we've seen many mechanical breakdowns on vehicles. Experience has shown that changing your fluids is the single most important preventive maintenance routine you can perform to avoid vehicle breakdowns. Yet, for many Vw owners, this seems to be one of the most neglected areas of maintenance. Thoroughly flushing your fluids at the proper intervals can help your car reach 150,000 miles and beyond! Changing your Vw power steering fluid prevents failure of expensive steering pumps, rack and pinions, and other steering related parts.

Vw Power Steering Fluid - G002000 CHF 11S
Vw Power Steering Fluid - G002000 CHF 7.1
FAQ: Can you mix mineral based CHF 7.1 Vw power steering fluid with synthetic CHF 11S or CHF 202 Vw power steering fluid?
Basic Overview Of How To Flush & Change Vw Power Steering Fluid For:
- Vw Passat 1998-2001
Some suggest that you don't need to change your Vw power steering fluid. We feel this isn't logical. A Vw power steering pump is just one component of concern. The moving internal components of the steering pump and steering rack and pinion mesh and wear with one another, creating metallic particles that contaminate Vw power steering fluid. It's important to change the Vw power steering fluid as a part of your preventive maintenance schedule. We recommend changing your Vw power steering fluid as a first step when attempting to solve hydraulic related issues, such as a noisy steering pump or the intermitted loss of power assisted steering. Vehicles operating in hotter climates or that are subjected to driving in heavy city traffic should have their Vw power steering fluid changed every 30,000 miles. It's good preventive maintenance, and is inexpensive when compared to the replacement of an Vw steering pump or Vw steering rack and pinion.
Blauparts stocks and sells high quality Ravenol SSF German made Vw power steering fluid that meets / exceeds Audi Vw specifications (i.e. G004000 and G002000 Vw power steering fluid specs). Customers should check their Vw owner's manual and subsequent factory service manual for what type of Vw power steering fluid is recommended for their vehicle.

Ravenol's innovative and technologically advanced lubricant product line has out performed many of the leading motor oil companies. They have been awarded formal approvals from leading vehicle manufacturers such as Mercedes Benz, Volkswagen, Vw, BMW, Porsche, Volvo, ZF, and many more. Most German automotive owners want only the best fluids. Blauparts believes in providing oils and lubricants that are formulated and engineered to meet your car's stringent specifications.
In 1984 the Audi 5000 was considered an innovative automobile. The 5000 was equipped with a unique hydraulic pump that simultaneously performed both the power assisted braking and power assisted steering. This dual functioning system was used on many Audi models up until around 1996. The 1996 S6 model with 5 Cylinder 20 Valve engine was the last to use it.
Back then, a double vain hydraulic pump performed these two functions (power assist braking and power assist steering), requiring an advanced hydraulic oil that could properly function under the inherent high operating pressures and temperatures generated within this system. This unique system spawned a new era of fluids, a mineral based (CHF 7.1) hydraulic steering fluid in the early 1980s, and later a synthetic based fluid (CHF11s) in the 1990s.
Today, Audi and Vw models use a much simpler design (compared to what was used back in the 1980s and 1990s). The single vain steering pumps of today typically only generate hydraulic pressure for the power assisted steering function and has a lower operating temperature. The mounting location of the steering pump differs depending on model and engine configuration and may be This variable may mounted near other heat generating components (i.e. turbochargers). Today's power steering fluid must facilitate proper steering pump operation, withstand high temperatures, and ensure reliably over a long period of time and under all vehicle operating conditions.
Ravenol SSF sets the standard for innovation in the field of power steering fluid. With their propriety formulation, Ravenol SSF covers the demands of most popular European hydraulic steering pump designs, past and present, single vain and double vain. Note the broad list of specifications Ravenol SSF power steering fluid meets / exceeds above.
There has been a good measure of controversy over this question. Here is what our own experience shows. Over the last decade we've had no compatibility problems mixing the CHF 7.1 non-synthetic mineral base fluid and the CHF 11S synthetic based Vw power steering fluid. No problems with our own vehicles and no problems with our customers vehicles. Our success in mixing the 2 Vw power steering fluids coincides with the Vw tech bulletin 48-89-T07 issued in November 1989. It states "The new [synthetic Pentosin 11S] and old power steering fluid [non-synthetic Pentosin 7.1] can be mixed if necessary ... the part number [remains] unchanged." So according to Vw, you can mix the 2 Vw power steering fluids. Even though the composition of the fluid changed (CHF 11S synthetic mineral oil vs CHF 7.1 non-synthetic mineral oil), Vw didn't even change the part number. All 1990 - on Vw models have come filled from the factory with the synthetic CHF 11S Vw power steering fluid (G002000). Please Note: Never mix generic power steering fluid or other fluid with the CHF 7.1 or CHF 11S Vw power steering fluid (G002000). If you or someone else did, flush the Vw power steering fluid as described below.
Refer to the factory manual for Vw hydraulic system instructions.
We recommend having an A.S.E. certified Vw mechanic change your Vw power steering fluid.
Always wear gloves and wear safety goggles when handling Vw fluids.
Never start the vehicle without Vw power steering fluid in the fluid reservoir.
