Product Details

The Standard Ignition EOS53 is an OE-style engine oil separator used in the crankcase ventilation system to help manage oil vapor separation in turbocharged and naturally aspirated engine layouts found across select Audi A3, A4, A5, A6, Q3, Q5, Q7, TT Quattro, TTS Quattro, and Volkswagen Atlas, Tiguan, Jetta, and Passat applications. This part cross-references Beck/Arnley 045-0472 and Gates EMH954 for the same application. It also references OE and aftermarket numbers including 06K103495AF and EOS153. If you are replacing a worn separator on a 2017-2021 Audi A4 Quattro or a 2018-2022 Volkswagen Tiguan, EOS53 provides a direct-fit service part for the listed vehicles.

Common Problems This Part Can Address

  • Oil vapor buildup in the crankcase ventilation system
  • Oil residue entering intake plumbing
  • Rough idle caused by separator wear or internal restriction
  • Check engine concerns related to ventilation system faults
  • Oil leaks at the separator sealing surface

Installation Notes and Tips

  • Verify engine code and vehicle build date before ordering, especially for 2021 Volkswagen Passat models noted through 07/26/2021.
  • Replace the gasket during service and inspect the mounting surface for contamination or damage.
  • Confirm hose and port routing before removal so the new separator is installed correctly.
  • Check for cracked breather lines or hardened seals that could affect system performance after installation.

Quality Assurance
