Jetzt Helfe Ich Mir Selbst (Vol. 200+) : Modern Car Owner’s Guides
The repair manuals from the German series "Jetzt helfe ich mir selbst" describe in a very clear and understandable way how your car is constructed and how it can be maintained in the best possible way. These Motorbuch Verlag manuals provide much more information than the owner's handbook, supplied by the manufacturer with a new car.
Previous editions of the series "Jetzt helfe ich mir selbst" were complete workshop manuals, but because of the complex technology of modern passenger cars, the publisher has changed the formula from number 200.
These books still provide a lot of information about the construction and operation of the car, but only works that can be carried out easily by the owner (i.e. without special tools or electronic measuring equipment) are included.
For example, a complete engine overhaul is not described, but you will find instructions for easier jobs like the replacement of brake pads or components of the cooling system.
The owner's books from the series "Jetzt helfe ich mir selbst" provide a wealth of information. They are intended for the handy DIY-mechanic as well as for those who simply want to know how a particular car works. Over 15 million books from this series have already been sold.

Frequently Asked Questions
How do the newer "Jetzt helfe ich mir selbst" books (from Vol. 200) differ from the older ones?
Modern vehicles have become significantly more complex, often requiring specialized electronic diagnostic equipment for major repairs. In response, volumes from number 200 onwards have shifted focus. While they still explain the car's technology in depth, the repair instructions are limited to tasks that a handy owner can realistically perform with standard tools, such as changing filters, spark plugs, or brake pads.
Do these modern volumes include wiring diagrams?
No. Due to the high complexity of modern multiplexed electrical systems, wiring diagrams are no longer included in the series starting from Volume 200. Instead, the books provide detailed information on fuse layouts, bulb replacements, and battery maintenance.
Can I use this book if my car breaks down on the road?
Every volume includes a dedicated "What to do in the event of breakdown" section. This chapter provides immediate troubleshooting steps for common issues like a dead battery, starter motor failure, or cooling system overheating, helping you identify if the problem can be fixed on the spot or requires a professional.
