The 1.8 20-valve turbo engines of this era need regular timing belt and water pump service, and ignition coils and oil sludge in the turbo feed line are common faults. On the 2.5 TDI V6 of this era, camshaft and cam follower wear and the injection pump are the jobs people look up most.

On a 1998 car the 10th character of the VIN is “W”, a quick way to confirm the model year before you order.

How we make your manual. Audi sells access to its factory service information to owners and independent workshops. We do that work for you: we take the service information for your VIN and build a PDF that matches your engine, gearbox and equipment, with the wiring diagrams for your exact car. Delivery takes 12–24 hours.

The PDF has a full index, multi-level bookmarks, links between pages and working search. It opens on any computer, phone or tablet without extra software, and you can print the whole manual or just the pages you need in the garage.
