No water in fuel light came on.... however when I cycle key I get P2269. P2269 is "water in fuel condition" what does this mean???

 

I would err on being cautious and would intrepret that literally as "water in fuel" even if the WIF light is not illuminated. Perhaps the indicator light circuit could somehow be defective and the sensor is working properly and tripping the code.

I would drain all the fuel out of the fuel filter drain (yellow handle) into a clear bottle and see if any water comes out. You might even pull the fuel filter out and clean the WIF contacts in the bottom of fuel canister area.

I would put in a fuel additive that either emusifies or demulsifies (your choice) water in diesel for good measure.

If you still get the code, I would call the Dealer Service dept. and ask them what you should do. They may say not to drive it and will want to tow it in just to be safe.
