OE 0002309011 — Airmatic Compressor for Mercedes-Benz

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the cooling system family — always confirm dimensions and connector layout before you swap.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest cooling system reference and narrow by build year. Send photos and we will cross-check the number for you.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Incoming batches pass a dimensional check, a material look-up against the cooling system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a airmatic compressor the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded airmatic compressor transfers stress to neighbouring components, so a small repair can grow into a full cooling system rebuild. Book the replacement once the symptom is repeatable.
