Second Hand Mercedes-Benz MB100 Air Flow Meter

The MB100 is a van powered by carburetted or mechanically injected diesel engines depending on variant, and none of these engine types use an air flow meter — that component belongs to electronically managed fuel injection systems, which the MB100 did not feature. If your van is running poorly or you have been advised to replace an air-related sensor, the part you may actually need is something like an air filter, idle speed adjuster, or a component specific to the injection pump rather than an air flow meter. It is worth describing your symptoms to a breaker who specialises in Mercedes commercial vehicles, as they will be able to identify the correct part for your specific engine.

No variant of the MB100 — whether the earlier pre-1991 models or the updated versions produced through to the mid-1990s — was fitted with an electronically controlled engine management system that would require an air flow meter. The engine range across the MB100's production life consisted of carburetted petrol and mechanically governed diesel units, neither of which uses a mass air flow or air flow meter sensor. If you have seen this part listed for the MB100, it is likely a cataloguing error.

Almost certainly not, as the MB100 was never built with the type of electronic fuel injection system that an air flow meter works with. It is possible there has been a mix-up with another Mercedes model — such as a Sprinter or a car from the same era that did use electronic injection — or the part has been miscategorised. Confirm the issue you are trying to fix with your breaker and give them your engine code from the V5 or a VIN check, so they can identify the correct component for your specific van.

If you are chasing a fuel or air-related fault on the MB100, the relevant parts will depend on your engine type — diesel owners should be looking at injection pump components, fuel filters, or glow plugs, while petrol variants used a carburettor, so carburettor rebuild kits or jets may be more relevant. An air filter or intake hose could also be worth checking if airflow to the engine is restricted. Describe your symptoms clearly to a Mercedes commercial vehicle breaker, as they will be best placed to point you toward the correct used part.
