That Pesky Check Engine Light and the Code Reader Volvo VIDA DiCE

Spending from $45.00 to $100.00 for an OBD2 Code Reader could save you hundreds of dollars in repair costs. Best of all the code readers are easy to use. The OBD2 Code Reader package Volvo VIDA DiCE has an instruction book that tells you how to use the OBD2 Code Reader and definitions for the codes.
When that pesky "check engine" light comes on and you take the car to the repair shop to see what the problem is, the auto mechanic will read the code and tell you that a part needs to be replaced or a repair needs to be done, depending on the code reported, when this is not always the case. The fee that the repair shop charges for this service (attaching their OBD2 code reader to a vehicle to read the code) usually is the price they paid for their OBD2 Code Reader.
Nice deal for the  Volvo VIDA DiCE repair shop, every time the auto mechanic reads the code on a customer's vehicle they get reimbursed the cost of their OBD2 Code Reader. What is wrong with this picture?
As many times as not, a code detected by the on-board computer can be caused by a momentary or temporary situation in the engine, which does not necessarily need repair.
So ask Autocom cdp pro yourself – "Do I want to pay the fee at the repair shop to have them read the code that made my check engine light come on? OR just get my own OBD2 Code Reader - pay for it one time and use it as many times as is necessary and save money?"
Read the instruction book that comes with your OBD2 Code Reader
for complete instructions.
Briefly --> how to use the OBD2 Reader
If your "check engine light" is on, plug the OBD2 code reader into the receptacle, mb star c3 typically found under the steering wheel, and refer to the code reader book to find out what the code means. We recommend that you erase the code and if the "check engine" light comes back on within a few days, with the same code then, more than likely, repairs should be done.
