Belt tensioner J854/J855 basic adjustment

Renewing belt tensioners on VAG MQB vehicles

On vehicles from the Volkswagen MQB family, such as the Audi A3 (8V), Seat Leon (5F), Skoda Octavia (5E) and VW Golf (AU/5G), a basic adjustment should be carried out after renewing the J854/J855 belt tensioners. Jifeline Remote Diagnostics can perform this basic adjustment for you. Transporting the car to a VAG dealer workshop is therefore not necessary. The damage repair process runs smoothly and efficiently this way.
