AutoFix – the most advanced car repair tool you can buy Autofix

For a new generation of vehicles, welcome to an all-new repair guide. The Haynes Manual has inspired and helped DIY repairers for more than 60 years, but today’s modern vehicles come with new challenges that can only be tackled by a digital product.

When we first began selling manuals in the 1960s, vehicles were simple to maintain and there were relatively few models on sale. Today, electronics are a vital part of how your vehicle operates and there are more than 100,000 different variants of make/ model/ body type/ gearbox and engine. So at Haynes, we knew that to continue offering a great product, we needed to take a brand-new approach – nothing less than a reinvention of the repair manual. Modern cars are equipped with dozens of sensors and ECUs (control units). Today, the first step when servicing a car is to plug a diagnostic tool into the OBD (on-board diagnostics) system of the vehicle.

So, we’re putting an electronics diagnosis module in the hands of DIY repairers for the first time. Enter a fault code and follow the instructions to test components in order, and establish the likely cause of a problem. Our tool goes far beyond what commonly available fault code readers offer, and puts you, the car owner, back in control. Even if you don’t choose to complete the repair, you will know exactly what the problem is when you hand it over to a workshop.

With make and model coverage of around 90% of cars, AutoFix takes the help you get from Haynes to a new level. And at an introductory price of £25, AutoFix can be accessed via your favourite digital device – phone, tablet or desktop – and, as with Haynes online manuals, you get to keep your purchase for as long as you need it. No deadlines, no pressure to get that job finished before time runs out, no stress.
