Acknowledgements Thanks are due to Volkswagen AG for the supply of technical information and certain illustrations, to Duckhams Oils who supplied

lubrication data, and to the Champion Sparking Plug Company who

Sykes-Pickavant Limited provided some of the workshop tools. Special thanks are due to all those people at Sparkford who helped in the production of this manual.

supplied the illustrations showing the various spark plug conditions.

About this manual [ts aim The aim of this manual is to help you get the best value from your vehicle. It can do so in several ways. It can help you decide what work must be done (even should you choose to get it done by a garage), provide information on routine maintenance and servicing, and give a logical course of action and diagnosis when random faults occur. However, it is hoped that you will use the manual by tackling the work yourself. On simpler jobs it may even be quicker than booking the car into a garage and going there twice, to leave and collect it. Perhaps most important, a lot of money can be saved by avoiding the costs a garage must charge to cover its labour and overheads. The manual has drawings and descriptions to show the function of the various components so that their layout can be understood. Then the tasks are described and photographed in a step-by-step sequence so that even a novice can do the work.

[ts arrangement The manual is divided into thirteen Chapters, each covering a logical sub-division of the vehicle. The Chapters are each divided into Sections, numbered with single figures, eg 5; and the Sections into paragraphs (or sub-sections), with decimal numbers following on from the Section they are in, eg 5.1, 5.2, 5.3 ete.

It is freely illustrated, especially in those parts where there is a detailed sequence of operations to be carried out. There are two forms

of illustration: figures and photographs. The figures are numbered in sequence with decimal numbers, according to their position in the Chapter — eg Fig. 6.4 is the fourth drawing/illustration in Chapter 6. Photographs carry the same number (either individually or in related groups) as the Section or sub-section to which they relate. There is an alphabetical index at the back of the manua! as well as a contents list at the front. Each Chapter is also preceded by its own individual contents list. References to the ‘left’ or ‘right’ of the vehicle are in the sense of a person in the driver's seat facing forwards. Unless otherwise stated, nuts and bolts are removed by turning anti-clockwise, and tightened by turning clockwise. Vehicle manufacturers continually make changes to specifications and recommendations, and these, when notified, are incorporated into our manuals at the earliest opportunity. Whilst every care is taken to ensure that the information in this manual is correct, no liability can be accepted by the authors or

publishers for loss, damage or injury caused by any errors in, or omissions from, the information given.

Introduction to the Audi 80, 90 and 4000 The ‘new’ Audi 80 was announced in late 1978 and was available

in the UK in March 1979. The equivalent North American Audi 4000 became available in 1980. These models are similar to the ‘new’ 100

range, but differ from the earlier Audi 80 (UK) and Audi Fox (North America) by incorporating a sloping bonnet, an additional side window behind the rear door, and wrap-around plastic bumpers. The Coupe version incorporates front and rear spoilers and side rubbing strips, while the top saloon model, the CD, incorporates a front spoiler and side rubbing strips. The Audi 90 was announced in late 1984 and was available in the

UK in early 1985. This model has the same bodyshell as the 80, but has dual headlamps, foglamps and indicators set in the front bumper, and a higher level of trim and equipment. The model range is comprehensive and offers a choice of trim, four

or five-cylinder engine, and four or five-speed gearbox or automatic transmission. Full instrumentation is provided together with electric windows, a central locking system and power steering, according to model. UK models are available with a carburettor or fuel injection

engine — North American form.

models are only available in fuel injected
