Does GPF Warning Affect Vehicle Driving?

GPF warning will affect vehicle driving. Although the vehicle can continue to drive when the GPF warning is on, the power of the vehicle will decrease. The main reason is that after the GPF is blocked, it will increase the exhaust back pressure, resulting in a decrease in engine power. Methods to deal with GPF warning: When this problem occurs, it means that the particulate filter has been blocked. After driving for a period of time, the particulate filter will most likely light up, which is a normal situation. You can drive at high speed for a while to raise the exhaust temperature and burn off the particles in the GPF, or you can drive more on the highway to clean the particulate filter. If the problem still persists, you need to go to a specialized repair shop to remove the GPF and clean it manually. Notes on GPF: GPF refers to the particulate filter. Many vehicles install a GPF in the exhaust system to meet the strict China VI standard. However, the GPF needs to be cleaned after being used for a period of time.
The GPF warning light will definitely affect vehicle driving. I remember last month when my car was driving in the city, the GPF light suddenly came on. The car felt noticeably sluggish, and even with the accelerator pedal fully pressed, acceleration was slow, with the RPM struggling to rise—it was like dragging its feet. At that time, fuel consumption skyrocketed, jumping from the usual 7 liters per 100 km to 9, which really hurt my wallet. The technician said the GPF is a particulate filter designed to trap impurities in the exhaust, and the warning indicates it's clogged or the system has an issue. If not addressed promptly, the vehicle will automatically enter limp mode, limiting power and forcing it to crawl at low speeds, making long-distance driving a nightmare. Later, I rushed to the dealership for a cleaning and regeneration treatment, and the car returned to normal. So, never ignore the warning light—it ruins the driving experience and burns money. Regular checks during routine maintenance can prevent such issues.
Speaking of GPF warnings, I recall a costly lesson in saving money. Previously, I ignored it out of convenience, only to find my car driving like an old ox pulling a broken cart—sluggish acceleration and struggling uphill, significantly degrading the driving experience. Worse yet, neglecting the warning led to severe clogging, eventually requiring a full GPF unit replacement that cost over 3,000 in repairs—a huge loss. For minor clogs, you can perform regeneration driving on the highway: maintain speeds above 80 km/h for half an hour and use heavy throttle to let the system self-clean, saving both money and hassle. However, long-term neglect can impair engine performance, increasing fuel consumption by 10%-20%, which is even more unkind to your wallet. My advice: act immediately upon warning to avoid compromising travel convenience over small savings.
