OE 077121004H — Water Pump for Audi

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.

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.

Position depends on the platform. On most Audi applications the water pump sits on the cooling 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.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded water pump transfers stress to neighbouring components, so a small repair can grow into a full cooling system rebuild. Book the replacement once the symptom is repeatable.

A supersession happens when the maker revises a water pump and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 077121004H we list the current reference; ask our desk for written confirmation before a large order.

Yes. Sample lots of 077121004H 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.
