Service & Maintenance Guide

Service Icon

Minor Service - Oil Service

Every 10k is a minor service - oil and filter. Do not follow the factory 15K and go 7k for tuned vehicles.Oil is cheap, engines are not!

Service Icon

Intermediate Service

Every 30k is an intermediate service - oil and filter, cabin filter & air filter, brake fluid flush, remote batteries.

Service Icon

Major Service

Every 60k is a major service - oil and filtercabin filter & air filter, remote batteries, brake fluid flush, fuel filter, DSG gearbox oil and filter (unless automatic, manual, tiptronic or multitronic), spark plugs and haldex oil.

Service Icon

Intermediate Service

Every 90k is another intermediate service - same as 30k plus a poly belt / accessory belt.

Additional: Water pump & timing belt and poly belt on belt driven engines should be done every 60k.

Replace Haldex fluid every 30k rather than 60k, Gearbox oil change at 40k for DSG is advised. Front and rear differential oils are "longlife" but replace every 60k to be safe.
