Will it fit my Mercedes B Class?
Chain- or belt-driven and mounting differ by engine code — this is an engine-internal part, so get the exact code right before ordering.
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 oil pump needs replacing
- Low oil pressure warning light
- Rattling/knocking that gets worse with revs
- Oil pressure gauge reading low
- Engine running hot
Fitting it yourself
Usually needs the sump off, sometimes the timing cover too — not a casual DIY job for most engines. Don't keep driving on a low oil pressure warning.
