Will it fit my Mercedes E Class?
Pre-cat (upstream) and post-cat (downstream) sensors are different parts — check which one your fault code points to, and how many your engine has.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Mercedes E Class oxygen sensor needs replacing
- Engine warning light (O2/lambda code)
- Poor fuel economy
- Rough idle or hesitation
- Failed emissions/MOT
Fitting it yourself
Usually a single plug and a thread into the exhaust — quick if it's not seized. Penetrating oil helps on an old sensor.
