Will it fit my Seat Ateca?
Must be the correct emissions-spec cat for your engine and year, or it'll fail MOT. Type-approved units only.
Tip: filter by your reg on eBay's compatibility check, or match the part number stamped on your old unit.
Signs your Seat Ateca catalytic converter needs replacing
- P0420 / catalyst efficiency code
- Rattling inside (broken substrate)
- Failed emissions/MOT
- Sluggish, rotten-egg smell
Fitting it yourself
Bolt-on or welded depending on setup. Lambda sensors often transfer over.
