If you need to execute fixes to your Generic XOR Competition then it is usually a good idea to have a Workshop Manual for reference if perhaps you need to know how to remove a particular part much like the Wheel Bearing and match it again appropriately.
Generic XOR Competition Workshop Manuals can offer you particular diagnostic guidelines on your car therefore if something is faulty it helps you find out what the situation is and some ways to resolve it. You can then decide if this can be done yourself or that the job is just too big you are able to book your XOR Competition in with a local car garage.
