7 Car Repair Services You Can Get for FREE

Just because you drive a Mercedes-Benz or any late-model car doesn’t mean that you need to pay for every auto repair and maintenance. In this article, we discuss several car repair services that you can get completely free. We aim to help you save money for maintaining and repairing your car. After all, who doesn’t love free stuff, especially car service?

If you live in the United States, you can get several services for free. What exactly do we mean? Here are all the free services at Pep Boys, Advance Auto Parts, AutoZone, Mr. Tire, and more.

Free Check Engine Light Service

Whether you have a misfire or evap system leak, your auto parts store can scan the car for free and tell you what is wrong with your vehicle. Autozone, PepBoys, Advance Auto Parts, O’Reilly, and even some auto repair shops offer this service for free. You don’t need to pay a $120/hr rate for a service that only takes 5 minutes, and you can quickly get it for free.

We recommend that all car owners have at least a simple OBD II reader; they cost less than $20 and come in handy if your check engine light comes on during a long trip. Check out these best-selling OBD II scanners on Amazon. If you don’t have an OBD-II scanner and the check engine light is on, head to your auto parts store, and they will scan it for free.

While this is an excellent free service, they will only scan the engine control unit (ECU), which is the unit that triggers the check engine light/service engine soon light. The auto parts store scanners can not scan other systems in your car; you need a more powerful scanner to troubleshoot your vehicle further. Also, they will retrieve the fault codes, but in most cases will not erase the light due to the store’s policy.

If you do your car repairs and maintenance, consider investing in an OBD II scanner that can read and erase the check engine light and the transmission, SRS, ETS, ABS, Traction Contro, A/C, and airbag. A good choice is the YOUCANIC full system scanner with bidirectional support.

A YOUCANIC full system diagnostic scanner can help you troubleshoot Mercedes-Benz problems by interpreting fault codes, performing diagnostic tests, and resetting maintenance reminders. This tool provides valuable information for informed decision-making on repairs and maintenance, making it a powerful asset for DIY mechanics and professional technicians.

While these scanners work the same way that the OBD-II scanner at Advance Auto Parts and AutoZone work, they can access almost all of the control systems on your car, not just the check engine light from the ECU. Watch, for example, how easy it is to check and clear the Airbag SRS fault codes using the two scanners mentioned above.

Free Electrical System Test and Diagnosis

Advance Auto Parts, Autozone, PepBoys will test the alternator, starter, battery, and other components for free.
