QS10852 Description

The Audi V8 Timing Tool Kit QS10852 is a specialized holder designed for professional mechanics servicing VAG 3.7 and 4.2 liter gasoline engines. This special tool for Audi A8, S6, Volkswagen Phaeton and Touareg ensures precise positioning of the camshafts, preventing them from shifting when replacing the timing belt. The tool prevents distortions and ensures easy and accurate assembly of the drive.

An error when fixing the 4.2 V8 camshaft timing without this holder often leads to incorrect belt tension, failure of the valve timing phases, and even piston-to-valve collision. Thanks to the QS10852 bracket, the technician reliably blocks both camshafts, preventing them from turning. Suitable for Audi A6, A6 Quattro, A8, S6, S8, RS6 models, as well as Volkswagen Phaeton and Touareg with codes AKC, AQG, BFL, AKB, ANK and others.
