Hi guys, I have just bought a 96 GQ Patrol 4.2 TD 330k on the clock. The water in fuel light has come on. It wasn't on when i bought it but only a few hours later when it was home i went to start it again the warning light was showing and the charm sounding when i turn the ignition off. Today i opened the bottom of the filter and drained the water until i got strait diesel. Some other mold like bits came out too.

The problem is the light is still on. Is this normal? Does it go off after a period of time? Im worried to drive it with this light on in case i irreversible damage.

I have just bought a CAV fuel filter to go in which fits into the original head in the hope that i can monitor the water contamination without relying on the warning light.

Looking for your opinions and experience on this issue.

Thanks.
