The Audi Q5 can try to turn off the vehicle and restart it if the EPC light is on. If the light goes out, it can continue to drive. If the light is still on, it cannot continue to drive and needs to be checked and repaired. There are two possibilities for the EPC light to be on: 1. The throttle is dirty and should be cleaned; 2. The brake light is not on, and the brake switch and wiring need to be checked; 3. The fuel problem will also cause the EPC fault light to turn on. It is recommended to go to the 4S shop for inspection as soon as possible. The Audi Q5 is a medium-sized SUV model under FAW-Volkswagen Audi. The length, width and height of the car are 4629 mm, 1898 mm and 1655 mm respectively, and the wheelbase is 2807 mm.

That day I was driving my Audi Q5 on the highway when suddenly the EPC light came on, which really gave me a scare. When this light comes on, it's no joke—it means there's an issue with the electronic throttle system. I immediately reduced my speed to around 60 and slowly made my way to the service area. At the repair shop, the mechanic told me it was caused by severe carbon buildup in the throttle body. To be honest, if I had stubbornly kept driving, at best I might have just experienced sluggish throttle response, but at worst, the car could have stalled right in the middle of the highway, which would have been extremely dangerous. Especially with cars like Audi that have complex electronic systems, pushing through could even damage the ECU. Now, whenever I see the EPC light come on, I pull over immediately—calling a tow truck is the safest bet.

My Q5 last lit up the EPC light during evening rush hour in the city. When this light came on, I knew something was seriously wrong, as it controls the entire vehicle's power distribution. I lightly pressed the accelerator and noticed the engine responded very slowly, so I immediately turned on the hazard lights and slowly moved to the side of the road. Later, it was diagnosed as a faulty throttle pedal sensor, which was fixed after replacing the part. In my opinion, it's okay to move the car a short distance to a safe area, but definitely don't attempt a long-distance drive. I've seen people stubbornly drive to the repair shop, only to suddenly lose power halfway and nearly cause a rear-end collision. The newer Q5 models have even more sophisticated electronic systems, where minor faults can trigger chain reactions—it's really not worth the risk.

The EPC light came on while my Q5 was climbing a slope, and I could clearly feel the lack of power. After checking some materials, I learned that this is an alert from the electronic throttle control system, with common causes including sensor failure, wiring short circuits, or throttle sticking. I tried restarting the engine twice, but the light remained on, so I quickly drove to the nearest repair shop. In fact, continuing to drive forcefully could trigger the engine's speed limiter protection, restricting the speed to around 40 km/h at most. It gets even more troublesome if the transmission can't shift gears, especially for automatic vehicles. It's recommended to safely pull over and inspect immediately. If you need to move the car a short distance, avoid sudden acceleration.
