Can I drive with this?
Choose the symptom or warning light, and optionally your vehicle and any code you have read. You get CarFaultIQ's driving guidance for it, the signs that mean stop, and the records for your vehicle.
Whatever this page says: stop driving if there is smoke or fire, the brakes or steering stop working normally, a red warning light or flashing check-engine light appears, or the temperature gauge reaches the top.

Drive with caution
Limited driving may be reasonable. Keep trips short, avoid heavy loads and long highway runs, watch for any change, and arrange a diagnosis.

Why this result
- CarFaultIQ's page for "Water in fuel warning: meaning and what to check first" gives: Drive with caution. Read the guidance
Your vehicle and year add context below but do not change the level: the level comes only from the guidance for the symptom and code.
Stop driving if
- Drive with caution and drain the separator promptly — water reaching a diesel injection system can cause corrosion and expensive injector or pump damage.
Sensible next step
Arrange a diagnosis soon, and stop if the symptom gets worse or a new warning appears.
What to check first
- Drain the water separator following the procedure in the owner's manual
- Note where the vehicle was last refuelled if the warning appeared shortly afterwards
- Replace the fuel filter if it is at or near its service interval
- Have the fuel system inspected if the warning returns quickly after draining
