OK guys,
I have a totally stock "06" CRD Sport with 25k on it soon to be out of warranty but I have never unplugged or changed the fuel filter. So do I unplug it, keep running her, change the head and filter after warranty?........ so on and so on.

Just periodically bleed the air out of the head to prevent the heater from running dry or hitting the "limp mode" under acceleration, just when you need to get up to speed. and if you don't want to change a filter by the side of the road, replace the element according to the service interval.

Go to your dealer and get the new head unit and heater plug connector. They might even perform the job for you since you are still under warranty. I have been given 4 replacement units all for free. The last one has been re designed with a new part number and a new connector for the heater. Part # 68043089 AA separator fuel 68043086 AA wiring kit new connector. Good luck

and that is?

Hehehe. I don't know, I change mine by the side of the road.

I don't have service records for mine, but my filter plugged at 55k. I suspect the interval is 24k or 30k miles.

The owner's manual is just suggested guideline(s) - filter maintenance interval depends on where fuel is usually purchased:

- the small back-street, last-ditch station, where the only vehicle on the premises belongs to the attendant, is a sure-(don't)fire candidate contributing to requirement for frequent inspection\replacement

- the local Flying V\similar, which is always full of Diesel vehicles, would likely qualify for extended intervals, where yer filter would remain beige thruout the year

Similar with air filter - paved streets usually gets extended interval - off-road requires frequent inspection\replacement - 'nuther words, the FSM\OM commandments are not writen in stone, inviolable

I have my heater plugged in and I never bleed it.(runs great!) I am hoping it burns to the ground so my gap insurance can kick in to pay off the loan. Then I will go buy another CRD on Ebay for half the price. Good plan right

Just as long as you aren't trying to pull into traffic and the fuel cuts on you, and that semi truck can't stop. Then your life insurance will have to cover it.

So does the water fuel light serve anything. I know it would not tell you the filter is clogged but would it come on in the presents of water in the filter?

Why do you think they call it the "water in fuel" light?

The fuel filter element has two sections - the WIF section is media which will pass fuel, but not the denser water, plus it is a centrifugal filter of sorts, where the heavier water component cannot navigate the corners, thus precipitating out and illuminating the WIF indicator - water is electrically conductive - Diesel fuel is electrically insulative

However, fuel can have water component where the ratio of water to fuel is not conductive enuff to trigger the sensor module - you will also know when the w\f ratio becomes excessive by the engine's response: ruff-running, black smoke: water quenches the combustion flame - also, water, at 20000psi, is as damaging as solid particles to the ucron-finished CP3 internals, solenoids, COV valves, and injectors

If you shut it down with no WIF indication, then start it some time later with WIF indication, the water has had time to precipitate out and trigger the alarm, and requires draining - if the alarm retriggers at start-up, you've likely picked up a load of contaminated fuel - if the drained fuel is clear, not cloudy, it can be reused after removing the water from the bottom of the tank - murky fuel is not a keeper

The lift pump pulls fuel from the bottom of the tank

Don't fergit to flush the fuel lines and filter cannister, and replace the filter

Thank you that is more like the answer I was looking for.

Surprisingly, the owners manual recommended service interval is 50k miles. You did good getting it to 55k.
