Yellow or Orange
Water in Fuel
The fuel filter has collected water and needs draining.
This symbol indicates that your fuel filter or water separator has detected an excessive amount of water contamination in your diesel fuel supply. Operating your vehicle with water in the fuel system can lead to significant damage to your fuel injectors and pump.
What to do
- 01Consult your owner manual to locate the fuel water separator drain valve.
- 02Carefully drain any accumulated water into a container as specified by the manufacturer.
- 03If the light remains on after draining, schedule an appointment with us at Miles Tech Auto immediately.
- 04Avoid driving long distances until the system is serviced to prevent internal engine damage.
Other common causes
A failing fuel filter, a faulty water sensor, or contaminated fuel from a gas station pump.
How we check it
We will perform a fuel system inspection and drain the water separator to ensure no contaminants have reached your high-pressure fuel components.
Symbols vary by make and model — always confirm in your owner's manual. If the light is red, the car feels different, or the light is blinking, stop and call us before driving further.
