OE 084409189B — Oil Seal for Audi

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 oil seal the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

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

OE 084409189B is the factory reference for this oil seal on selected Audi models. The Applications table on this page lists the confirmed rows — check trim level and build year against your own fleet before ordering, because one reference can cover several body variants.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.
