OE 893837398B — Window Regulator for Audi

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.

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.

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

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 electrical & sensors family — always confirm dimensions and connector layout before you swap.

Yes. Sample lots of 893837398B are used by QC teams to benchmark dimension, material and finish before a volume commitment. Send the reference and we will quote the sample alongside the production price.

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.
