OE 045903315A — Belt Tensioner for Audi

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 045903315A to confirm the right replacement.

Match three things: the code on the part you are removing, the build-year range in the Applications table, and the mounting points visible in the reference photo. If all three line up, 045903315A is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

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.

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.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.
