Can You Still Drive When the SVS Light Comes On in a Diesel Vehicle?

When the SVS light comes on in a diesel vehicle, it indicates an engine malfunction. The following details describe the issue: 1. The SVS indicator light in a diesel vehicle is an engine malfunction warning light, signaling that the engine has encountered a fault. The SVS light illuminates when the engine's ECU detects a malfunction after starting the engine, indicating that the vehicle's engine has a problem. 2. For such engine malfunctions, it is recommended to visit a 4S shop and consult a professional mechanic for diagnosis and repair. The first step is to check whether the issue is related to a sensor or wiring fault. If it is an engine malfunction, it should be addressed promptly. 3. To resolve the issue when the SVS light comes on in a diesel engine, you can attempt to start the engine. If it fails to start, the problem might be with the fuel pump, which may require replacement. 4. If the engine starts, the issue could be related to other sensor faults. In such cases, the vehicle may still be drivable, but there is a possibility that the fault could affect normal operation. It is advisable to have the vehicle inspected at a repair shop as soon as possible.
I've been driving a diesel car for over ten years, and the SVS light has come on several times before. I remember once on a long trip, the light suddenly lit up, and I quickly pulled over to check the manual. It said the emission system needed inspection. I asked a mechanic, and he said it might be a clogged DPF or a sensor issue. If there are no other warning lights, you can still drive slowly to the nearest repair shop, but definitely avoid accelerating or braking hard on the highway. So I drove carefully to the auto repair shop, and after inspection, it turned out the particulate filter had too much carbon buildup—just needed cleaning. If you drive too far with the light on, a small issue can turn into a major repair, costing more money, so don’t try to save by delaying. Safety comes first. Regular maintenance can help prevent such situations.
