Audi Q5 can still be driven when the EPC light is on. The EPC light indicates the vehicle's self-check process. If the light remains on after the engine is turned off, it may be due to a dirty throttle body, which should be cleaned promptly. If the EPC light comes on while driving, the driver can first conduct a basic inspection of the vehicle. If the light appears immediately upon starting the car, this is a normal situation as it indicates Audi's automatic vehicle inspection system and can be temporarily ignored. In terms of exterior design, this vehicle features sharp, angular detailing in elements such as the grille and headlights. The consistent use of straight lines throughout the body enhances the visual width of the car, further elevating its overall sporty demeanor.

I've been repairing cars for over a decade. A common issue with the Audi Q5 is the EPC light coming on due to problems with the electronic throttle system, such as a dirty throttle getting stuck or a faulty brake light switch. In such cases, never force the car to keep running. Last month, a driver continued for 20 kilometers after the light came on, and the engine stalled on an overpass—the towing fee ended up being more expensive than the repair. It's recommended to pull over immediately, turn off the engine, wait five minutes, and restart to see if the light goes off. If the light remains on, call a tow truck to take the car to the dealership to read the fault codes. Usually, cleaning the throttle or replacing the switch can resolve the issue. Remember, safety comes first—don't risk your safety or others'.

Last time when I was driving my Q5 on the highway, the EPC light suddenly came on. The throttle noticeably became heavier and the car couldn't accelerate. After pulling over and checking the manual, I learned this was an electronic system fault warning, possibly related to throttle pedal sensor or throttle position signal interruption. Although the car could still move at low speed, there was a risk of sudden power loss, especially dangerous during overtaking. I immediately turned on the hazard lights and pulled over, calling for roadside assistance. The mechanic said continuing to drive could cause more severe damage to the engine control unit, potentially adding thousands to the repair bill. This situation should be treated as seriously as when the airbag warning light comes on.

As a German car owner, I've found that the EPC light usually indicates electronic component issues. It could be caused by an air leak in the intake system or poor contact in the brake light switch leading to signal confusion. While these faults may seem minor, they can trigger the vehicle's protective mode and limit power output. I've experienced engine stuttering during sudden acceleration when the light was on. I recommend stopping immediately to check if the brake lights are functioning properly - sometimes a simple restart can temporarily resolve the issue. However, this is only an emergency measure. You must visit a professional workshop for diagnostic scanner testing as soon as possible, as prolonged driving with this issue can damage both the transmission and engine.
