Audi Q3 8U 2011–2018 2.0 TDI / 2.0 TFSI Intercooler 8U0145803B

Product overview

A replacement intercooler for the Audi Q3 (8U) with 2.0 litre TDI and TFSI engines, referenced to OE number 8U0 145 803 B. The intercooler cools compressed air from the turbocharger before it enters the engine, helping to maintain power, efficiency and safe operating temperatures.

Intercoolers are mounted low at the front of the vehicle, making them vulnerable to stone damage, corrosion and oil contamination from a worn turbo. A leaking intercooler can cause loss of boost, black smoke on diesels, limp mode and higher fuel consumption.

Vehicle compatibility

Listed fitment data lists the Audi Q3 (8UB, 8UG) from 2011 to 2018 with 2.0 TDI (88–135 kW) and 2.0 TFSI (125–162 kW) engines, in both front-wheel-drive and quattro versions. The table also includes several truck and bus entries that are clearly unrelated and should be ignored. Confirm by OE number or VIN before ordering.

Technical specifications

Installation requirements

Fitting is usually done with the front bumper removed. Inspect the boost pipes and turbocharger for oil or debris before installing a new intercooler, as contamination can damage the replacement. Use new seals or O-rings on the connections, check clamps are secure, and test for boost leaks. Workshop fitting is recommended.

Fitment checks before ordering

The part listing also mentions the RS3, which has not been confirmed in the fitment data. Intercooler design may differ by engine output and model year. Compare your existing part number and verify by VIN before purchase. Send us your VIN and a photo of the old unit's label and we will help confirm fitment before dispatch.
