Detailed Description

This Elring turbocharger inlet O-ring is built for vehicles that require a 57.85 mm inner diameter seal at the turbo inlet connection. It is used across many Audi and Volkswagen platforms, including 2009-2015 Audi TT Quattro, 2007-2013 Volkswagen GTI, 1998-2013 Audi A3, and 2009-2017 Volkswagen Tiguan applications. The FPM rubber construction is selected for sealing stability in high-temperature, oil-exposed engine areas where turbocharger inlet joints must remain secure and leak-free. If you are servicing an Audi Q3, Volkswagen Passat, or Volkswagen Beetle with the matching inlet size, Elring 697.240 provides the correct OE-style sealing specification.

What It Helps Address

• Air leaks at the turbocharger inlet connection
• Oil seepage around the inlet seal area
• Loss of boost consistency caused by a compromised seal
• Rough running or drivability issues related to unmetered air entry
• Service replacement for worn or flattened inlet O-rings

Installation Notes and Tips

Verify the inner diameter before installation; this part is specified at 57.85 mm. Inspect the mating surfaces for damage, contamination, or old seal residue before fitting the new O-ring. Use the correct service procedure for the turbo inlet connection and confirm the seal seats evenly after assembly.
