Brief Overview

This is a precision-engineered removal wrench designed specifically for Audi e-tron rear axle reservoir caps (2019 and later).

As a specialist supplier, you'll recognize the value of offering OEM-specific tools that reduce labor time and prevent customer damage claims. Pair this with timing chain tensioning tools for VAG 4.0L engines and rear axle service kits to build a comprehensive Audi service offering.
