OE 171837401B — Window Regulator for Volkswagen

Standard minimum order is 10 pieces per part number. Mixed orders that combine 171837401B with other electrical & sensors references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

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.

KingMay supplies OEM-grade aftermarket parts built to the 171837401B factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.

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.

Yes, if the alternate shares the same engineering envelope. Shortlist candidates from the Related OE References table, then check bolt pattern, electrical pinout and material grade. A difference in any of those three means it is a different part, not a substitute.

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the window regulator should be inspected, and reference 171837401B replaced if it measures outside specification.
