diagnostics

If you drive a performance or luxury vehicle made by manufacturers like BMW, Mercedes, Subaru, Land Rover, Porsche, etc., you’re probably no stranger to state of the art electronics, sensors, and control systems. At Harold's Used Auto Parts Inc, our technicians have the right knowledge, ability, and equipment necessary to keep your car or SUV in top-notch condition.

Your ECU regulates a wide variety of sensors, modules, and control systems, which affect the way your vehicle runs and drives. On occasion, an issue may arise that’s difficult to diagnose, typically involving sensor failure codes that are difficult to get rid of, or other dash lights and warning notifications that can’t seem to be diagnosed. In situations like these, your ECU is a likely culprit. Sometimes issues arise that require adjustments to be made or reprogramming to be performed in order to get rid of these issues once and for all.

If your car has been modified for performance, any number of issues can also begin to plague your ECU, as your car no longer performs in a way your programming deems acceptable. We can adjust parameters, reprogram modules, and get your car performing its best with the best technicians and technology in the business.

No matter your repair or maintenance needs, we’ve got you covered. For the best performance and luxury vehicle service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
