bbr 001-10-30439 Engine Oil Separator

Engine Oil Separator Overview

This bbr engine oil separator is a pressure-controlled, pre-assembled replacement for select Audi turbocharged applications. It is built with a synthetic material housing, an FPM seal, and an integrated breather valve for controlled crankcase ventilation performance.

Key Features

• Pre-assembled design for straightforward replacement.
• Pressure-controlled operation for consistent crankcase ventilation management.
• Synthetic material housing for durable under-hood use.
• FPM (fluoride rubber) seal for reliable sealing performance.
• Includes bolts/screws and seal as listed in the product data.
• Breather valve construction for oil vapor separation and ventilation control.

Detailed Description

Built for Audi A3, Audi A3 Quattro, Audi S3, Audi TT Quattro, and Audi TTS Quattro applications, this engine oil separator addresses crankcase pressure control in vehicles that rely on precise ventilation routing. The pre-assembled layout and pressure-controlled valve design support direct replacement of the original separator assembly, while the synthetic housing and FPM sealing material add durability in demanding engine bay conditions. Part number 001-10-30439 is also referenced for this application, and it cross-references 06K 103 495 AG.

Common Issues It Can Address

• Excess crankcase pressure from a worn separator assembly.
• Oil vapor control problems caused by a failing breather valve.
• Seal leakage at the separator housing interface.
• Rough ventilation performance from degraded internal components.

Installation Notes and Tips

Verify engine code and existing separator layout before installation. Confirm the mounting style and seal condition during service, and replace any damaged fasteners or related sealing surfaces as needed. This part fits 2015-2018 Audi A3 Quattro, 2015-2018 Audi S3, 2016-2018 Audi TT Quattro, 2016-2018 Audi TTS Quattro, and 2017-2018 Audi A3.

Quality Assurance

Part number 001-10-30439 is built to match the listed application requirements for select Audi models. The pre-assembled construction, included seal, and pressure-controlled breather valve reflect a service replacement design focused on proper fit and function.
