Before purchase, verify the OEM part reference 000 989 91 03 10 against your vehicle’s service documentation or fitment chart below.

Which Mercedes models use this febi hydraulic fluid?

Use this product when your vehicle’s factory specifications call for MBZ 343.0 hydraulic oil. It covers many models across decades — from W116/W123 sedans and early W124s through SL, S, E, CL and CLK platforms that list the referenced part number.

• Common compatible families: S-Class, E-Class, SL/SLK, CL/CLK, some SEC/SEL and diesel-limousine models.
• Check years and chassis in the product fitment section to confirm exact compatibility.
• Intended for systems that explicitly require MBZ approval 343.0 or part number 000 989 91 03 10.

How should I use this hydraulic fluid during service?

Drain and replace hydraulic fluid following the vehicle manufacturer’s service procedure to avoid air ingress and contamination. Use clean tools, an appropriate funnel or pump, and observe recommended fill volumes and bleeding sequences described in the workshop manual.

• Replace both bottles (2 liters total) if a full system drain and refill is required.
• Bleed hydraulic circuits per Mercedes repair instructions to remove trapped air.
• Dispose of old fluid responsibly at an approved recycling facility.

What should I expect from febi bilstein quality and packaging?

These bottles are produced recently by febi bilstein rather than long-storage stock, reducing the risk of degraded performance from age. The set is labeled for MBZ approval 343.0 and includes the cross-reference to Mercedes part number for straightforward identification.

• Packaged as a pair of 1-liter bottles to total 2 liters ready for service use.
• Clearly marked with MBZ approval and OEM reference 000 989 91 03 10.
• Shipped in protective packaging to prevent spills and preserve seals.

Will this fluid damage components if mixed with other oils?

Hydraulic systems are sensitive to fluid chemistry and contamination; always avoid mixing oils unless specified compatible by the vehicle manufacturer. If uncertain, complete a full flush and refill with the approved product to ensure correct system behavior.

• Do not mix with unidentified or incompatible hydraulic oils.
• If mixing has occurred, consider a full system flush and replacement.
• Use correct seals and follow torque/assembly specs during reassembly to prevent leaks.
