UV Adjustable End Plug

Part No. 33741B-10

Complaint:

  • Chatter on acceleration
  • Sluggish acceleration

Cause:

A cracked or broken adjustable end plug at the thin walled section below the external thread.


Correction:

Installing the Sonnax UV adjustable end plug with improved design and thicker walls correct these concerns and reduces possibility of future failure.

In Audi 01J and 01T units the adjustable end plug capping the UV reduction valve bore is often cracked or broken. The failure occurs at the thin-walled section below the external thread root. The Sonnax UV adjustable end plug 33741B-10 is designed with a thicker wall to eliminate this type of failure.

  • Improved design reduces possibility of similar failure
  • Simple thread-in replacement
