Tire Pressure Warning

Resetting your tire pressure warning light will not fix underlying issues, so if your TPMS indicator keeps coming on after topping off the tires with a gauge and checking for leaks, consult your owner’s manual or a mechanic to get to the bottom of things.

Engine Warning

If the check engine light turns on in your Audi A4 it can mean a wide variety of issues ranging from something as simple as a loose gas cap to something more serious such as a vacuum leak. The good news is that the light will often turn off if the issue or code that turned it on is fixed.
