Safety instructions

Do not keep driving when…

Follow the owner's manual and the exact recall notice for immediate instructions.

  • A red temperature warning appears or the engine overheats
  • Coolant is escaping rapidly, steam is present or the reservoir empties
  • The engine runs roughly and warning lights flash

What the source says

The documented condition

Audi published a diagnostic procedure for coolant loss on 2018 to 2024 SQ5 models with the V6 TFSI engine. It tells technicians to locate the leak precisely and warns that a small trace in the pump drip cup can be normal. A reproducible leak, rather than residue alone, is needed before replacing a component.

Manufacturer position

What the official procedure directs

Audi tells technicians to clean and dry the area before checking the level at idle and higher engine speed. A pressure test and pump vacuum-line check then identify whether a component is faulty.

Mileage context

Audi's bulletin is based on vehicle configuration and confirmation of an active leak, not a stated mileage threshold.

Repair paths and safe checks

Match the action to the evidence.

Official repair pathAudi or cooling-system specialist · Diagnosis before repair

Confirm the exact leak source

Have the cooling system inspected under Audi's published procedure. It combines a pressure test with a pump vacuum-line check and allows replacement only after the leak source is confirmed.

Boundary

Residue in the pump drip cup by itself is not proof that the pump must be replaced.

Safe owner checkBasic observation · 5 minutes

Log the cold coolant level

When the engine is completely cold and the vehicle is level, photograph the reservoir level and note any warning date. Repeat without opening a hot system.

Boundary

Never open a pressurized or hot cooling system.

Bulletin, recall or warranty?

Three official looking documents can describe the same bad part while creating very different rights. The document number, VIN scope and remedy language matter more than what someone called it at the service counter.

When a car is unsafe

A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.

Coolant keeps disappearing

Repeated top ups are evidence of a fault, not routine maintenance. Record the cold level and get the leak located before overheating turns diagnosis into engine repair.
