If you have to perform repairs on your own TGB Akros Tec then it is usually a great idea to own a Workshop Manual to keep just for reference if you want to know the way to strip off a specific component for example, the Wheel Bearing and fit it again in the correct manner.
TGB Akros Tec Workshop Manuals will give exact diagnostic information for the car so if something is not working it will help you identify what the problem is and ways to correct it. You will be able to assess if this can be done yourself or if the job is just too big it is possible to make a booking for your Akros Tec in with a local repair garage.
