Vauxhall Warning Lights Guide

Vauxhall dashboard warning light guide explaining common symbols, what they mean, and when to seek professional help for your Vivaro or Movano.

Modern Vauxhall vehicles have sophisticated onboard diagnostics that monitor every system. When a warning light appears on your dashboard, understanding what it means helps you decide whether to continue driving or call for help. At GSR Garage in Telford, we regularly diagnose warning light issues on all Vauxhall models. The engine management light (often orange or amber) can indicate anything from a loose fuel cap to a serious engine fault. Common causes we see on Vauxhall vehicles include infotainment screen freezing and gearbox bearing noise on 6-speed manual. If the light is steady, you can usually continue driving but should have the vehicle checked soon. If the light is flashing, stop driving immediately and seek professional assistance. The DPF warning light on diesel Vauxhall models indicates the particulate filter needs regeneration. gearbox bearing noise on 6-speed manual is a common cause. Driving at motorway speeds for 20-30 minutes may clear it. If the light stays on, professional cleaning or replacement may be needed. The ABS warning light indicates a fault with the anti-lock braking system. rear axle corrosion on Astra models can trigger this light. While the brakes will still work, the ABS may not function in an emergency stop. The airbag warning light should be investigated immediately as it indicates the supplemental restraint system may not deploy in a collision. For Vauxhall vehicles, the battery warning light could indicate EGR valve blockage on CDTI engines or alternator failure. The AdBlue warning light on diesel models means the system needs attention, and coolant loss from water pump on petrol engines is a common cause. Our team at GSR Garage in Telford has extensive experience maintaining and repairing Vauxhall vehicles for customers throughout the Shropshire.
