Schedule of current maintenance (Audi A4 B6)

Table of contents: Every 15,000 km or once every 12… ↓ Every 30,000 km or once every 2 years ↓ Additional works ↓

The suggested guidelines assume that the vehicle is serviced by the owner, as opposed to having the vehicle serviced by a dealership. Although this schedule is based on the manufacturer's recommendations, the intervals between most procedures can be shortened at the owner's discretion, for example, checking and changing lubricants and fluids should be done at intervals that ensure maximum engine or drive life. In addition, if the owner is interested in keeping the vehicle in a state of maximum readiness for possible resale, many procedures can be performed more frequently. We only welcome such an initiative.

Initial servicing and inspection of a new vehicle must be performed at a representative service station of the company in order to fulfill the terms of the warranty obligation. Such inspection is free of charge.
