Oil Separator, Crankcase Breather Valve VAG 1.8TFSI, 2.0TFSI OEM

Oil Separator / Crankcase Breather Valve – 1.8TFSI / 2.0TFSI VAG - OEM

Common problem with TFSI engines

Are you experiencing a poorly running engine, fault codes, or an unstable idle?

Then there is a high chance that the crankcase breather valve (oil separator) is defective or leaking.

This is a known issue with the 1.8 TFSI and 2.0 TFSI engines within VAG.

Common fault codes

• P2279 – Intake air leak
• P0171 – System too lean (Bank 1)
• P2187 – System too lean at idle (Bank 1)
• P0507 – Idle speed higher than expected
• P0300, P0301, P0302, P0303, P0304 – Misfires / cylinder misfire (most common)

Symptoms

• Very rough idling
• Hesitation or poor acceleration
• Higher idle speed
• Check engine light
• Vacuum leak / unmetered air

In many cases, this can be directly attributed to a defective crankcase ventilation system.

The solution

With this oil separator / crankcase breather valve, you will solve the problem properly.

OEM quality
Direct replacement
Restores correct crankcase pressure and air/fuel ratio

Why replace this part?

A defective crankcase breather causes:

• misfires
• unstable idle
• poor engine running

This part is often the cause.
