Will it fit my Mercedes B Class?
Sits in the intake pipework near the airbox — check the exact part number/connector for your engine code, as MAF sensors vary even within the same engine family.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Mercedes B Class mass air flow sensor needs replacing
- Hesitation or jerky acceleration
- Rough idle, stalling
- Poor economy
- MAF fault code
Fitting it yourself
Usually a couple of screws and a connector — one of the quicker sensor swaps, but try dedicated MAF cleaner first, since dirt is a common false fault.
