Product Details

• Article Number: 9F0094 — Ridex in-line fuel filter, an economy-tier OEM-equivalent replacement engineered to BMW factory specifications. Designed to provide reliable fuel filtration at a significantly lower cost than the genuine BMW filter.
• Filter Type: In-Line Filter — installs in the fuel line between the fuel tank and the high-pressure fuel pump. The cylindrical filter housing fits inline with the fuel feed circuit (typically located underneath the vehicle, near the fuel tank or along the chassis rail). No fuel pressure regulator integrated — purely a filtration component.
• Height: 263 mm — overall filter length. Critical dimension for fitment within the OEM bracket location.
• Diameter: 55 / 59 mm — outer dimensions of the filter housing (the dual measurement reflects the slight tapering between the two ends of the filter body).
• Inlet Diameter: 14.6 mm — diameter of the fuel inlet port (where unfiltered fuel enters from the tank). Matches BMW's standard inlet line spec.
• Outlet Diameter: 8 mm — diameter of the fuel outlet port (where clean fuel exits to the high-pressure pump). The smaller outlet diameter reflects the higher-pressure fuel flow downstream.
• Function: Removes water, rust particles, dirt, and microscopic debris from fuel before it reaches the high-pressure fuel pump and injectors. Especially critical on the N47 diesel — modern common-rail diesel injection systems operate at extreme pressures (1,800+ bar) with injector tolerances measured in microns. Even tiny contaminants can score injector internals, causing rough running, smoke, and eventual injector failure (a multi-million-shilling repair). A clean fuel filter is the cheapest insurance against this.
• Condition: New — factory-sealed in Ridex packaging.
• Manufacturer: RIDEX — AUTODOC's in-house OEM-equivalent aftermarket brand, produced in IATF 16949, ISO 26262, and VDA 6.3 certified factories.
• OEM Cross-References: BMW 13 32 7 823 413, BMW 1332782341301 (plus additional BMW cross-references) — direct equivalents to these original BMW part numbers.
• Vehicle Compatibility: Designed for the BMW X3 F25, particularly diesel variants including the sDrive 18d (N47 D20 C engine). Always verify against your vehicle's VIN or existing filter part number before purchasing.
• Service Interval: BMW recommends replacement every 15,000 km or 12 months — fuel filters are NOT lifetime components despite some myths to the contrary. For Tanzanian fuel quality conditions (occasional contamination from older underground tanks, water ingress during seasonal rains, varying diesel quality at smaller filling stations), consider shortening to every 10,000–12,000 km. Cheap insurance against the very expensive consequences of injector damage.
• Warning Signs of a Clogged Fuel Filter: Rough idle, hesitation under acceleration, sudden power loss at high speeds, hard starting (especially when warm), and in extreme cases, complete fuel starvation/stalling. If your customer is experiencing any of these symptoms before reaching the recommended service interval, suspect contamination from poor-quality fuel.
• Installation Note: Fuel filter replacement requires depressurising the fuel system before disconnection — work in a well-ventilated area away from ignition sources. Always replace the sealing O-rings/gaskets at the same time. Job typically requires 30–60 minutes for a competent mechanic.
