Parts for your 2020 Audi Q5-Exhaust gasket

2020 Audi Q5 exhaust gasket: usage, purpose and servicing advice

Factory sources confirm the 2020 Audi Q5 does use exhaust gaskets. Audi’s ETKA parts catalogue for the FY-series Q5 (MY2020, exhaust system and turbocharger sections) and Audi service information in erWin/ElsaPro list multiple sealing interfaces: crush/MLG gaskets at turbocharger-to-cylinder head on EA888 petrol engines, V-band sealing rings at turbo-to-catalyst/downpipe joints, and flange gaskets or sealing rings further rearward in the system. These gaskets are critical across 2.0 TFSI, 2.0 TDI and V6 variants, ensuring the exhaust remains leak-free and sensors read accurately.

An exhaust gasket’s job is simple but vital: it seals high‑temperature, high‑pressure exhaust flow between mating parts so exhaust gas doesn’t escape. On a Q5, that protects oxygen/NOx sensor readings, preserves turbo response, keeps cabin odours and noise at bay, and prevents hot gas from eroding nearby components. Audi specifies single‑use gaskets and clamps in several joints because they crush and conform during first fitment for a gas‑tight seal.

For servicing, exhaust gaskets aren’t a set‑interval item
