Parts for your 2012 Audi Q5-Oil seals

2012 Audi Q5 oil seals — what they do and when to sort them

Oil seals are absolutely relevant and used throughout the 2012 Audi Q5 (type 8R). Audi’s factory workshop documentation (ErWin) specifies radial shaft oil seals on the crankshaft and camshafts, as well as seals in the transfer case and front/rear differentials. The Audi Genuine Parts Catalogue (ETKA) lists part numbers for the front crank seal, rear main seal, camshaft seals, axle/diff flange seals and pinion seals. For vehicles fitted with the ZF 8‑speed Tiptronic, ZF’s technical manuals also detail input/output shaft oil seals. These technical sources confirm the Q5 relies on multiple oil seals to keep engine, transmission and driveline fluids where they should be.

On a 2012 Audi Q5, oil seals keep engine oil, gearbox fluid and diff oil from sneaking past rotating shafts and out onto the driveway. They also keep dust and water from sneaking in. Think of the front crank seal behind the harmonic balancer, the rear main seal at the bellhousing, camshaft seals in the timing end, plus transfer case and differential flange/pinion seals.
