The KFZ-Verlag GmbH offers technical specialist literature with extreme depth of detail. The publisher offers true-to-the-original repair guides for nearly every VW vehicle model, an average of 20 to 30 manuals per model. All repair instructions together make up the entire and extremely comprehensive workshop manual so that everything can be shown in detail for every repair on the vehicle. The service manual on the subject of "maintenance" deals with the area of vehicle maintenance and care and indicates the other titles in the book series so that you always know exactly which documents are required next. In addition to the savings factor of no longer incurring workshop costs by doing repairs in-house the publisher has designed its book series in such a way that only one specific vehicle section is dealt with per repair manual. The breakdown into different repair groups enables the professional or hobby mechanic to only acquire the books that are actually needed. Every Volkswagen AG authorized workshop works with exactly the same documents this is the only way to maintain your VW on an ongoing basis.
