OE 059109509C — Guide Rail for Audi

Aftermarket guide rail comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

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.

Wholesale pricing for 059109509C depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

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

Position depends on the platform. On most Audi applications the guide rail sits on the engine & fuel system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

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.
