ENGINE MAINTENANCE - INTRODUCTION
The service life of your vehicle's engine depends on the kind of maintenance it receives. Because of the inherent toughness, reputation for reliability and long life there is a tendency for some VW owners not to be as concerned with engine maintenance as they should be - particularly with vehicles not in the first flush of youth.

However, you should never forget that the engine is the heart of your Volkswagen. Also remember the old adage that "Prevention is better than Cure", it usually works out to be cheaper too. Remember the "Big Four".

The procedures described in this section of the manual, includes periodic engine checks and maintenance steps necessary for long and reliable operation. In addition there is a section which outlines the procedures which should be carried out in the case of a general engine tune up.

Maintenance Schedule
This section outlines the periodic checks and maintenance which should carried out on the vehicle's engine and the frequency with which they should ideally be conducted. By conducting routine maintenance you will maintain the efficiency and performance of the engine. In addition you will be more likely to spot any potential component problems or failures and rectify them, thus preventing a major engine failure.

However, the frequency of servicing tends on the conditions under which the vehicle is used, and the way in which it is driven. If the engine begins to struggle to start easily or starts to miss after it is warm (may indicate a tight valve) or before a long trip it is worth carrying out a quick tune up as outlined below.

Tune Up
Performance is best defined for our purposes as efficiency. This is because when an engine yields poor fuel economy and power, it is inefficient. Diagnosis should determine if the engine is using the right amount of fuel to produce the expected amount of power. If power or fuel economy drops, engine internals may or may not be the cause. To locate the source of poor performance, start with a tune up to rule out any problems which are a result of a poor state of engine tune.

A Tune Up consists of :

Complete the tune up yourself before carrying out any further diagnostic checks or if necessary taking the vehicle to a garage for further examination.
