Hi deegod,

I have a Ducatto 2.8 idTD and on hols recently I noticed something weird too. I had filled to about 3/4 and within a short space of time had gone down to 1/2. Fearing the worst, ie leaking tank, I pulled in and stopped. As I did so the needle slowly went down to empty.

Switched ignition off, then back on and the guage worked normally. Didn't do it again on hols nor since. Decided to leave well alone unless it becomes a regular problem. I usually put in an amount which I know corresponds to 1/2, 3/4 or full depending on mileage covered and estimate of fuel used. 100 miles = 1/4 tank of diesel.

Haven't heard of similar problems with this model.

Yep,

my previous van, a 2.8idTD used to do it as well, really strange and absolutely no pattern to it, sometimes go for months and it was ok, then i'd notice the gauge gradually falling to just uder 1/4 but i usually knew from the last fill that it should be reading about 3/4. After about 20-30 miles the gauge would then go back up again. Never did get to find out what the problem was as it only happened on a few occasions, i would imagine it was an erratic sender or sensor somewhere but can't be sure.

On the rear of the instrument cluster attached to the printed circuit board you will find a small black object around 1cm square, this is the voltage stabiliser...it's job is to stop erratic readings on fuel/temp/oil guages etc.
Sounds like yours may be faulty?

It's not very difficult to get the instrument panel out on the Ducato. I recently had to remove it and the complete dashboard to repair a faulty heater. You undo the 2 captive screws either side of the instrument panel and ease it towards you slightly, if you locate the speedo cable under the dash, it runs in front of the heater, and pull it slightly to the right, you will find that the instrument panel comes out sufficiently so that you can get a couple of fingers down behind the speedo to release the cable, it's just a sliding collar. After that you can easily remove the four cable connectors if you wish and the whole thing is free for you to do what you need to do. Changing the instrument bulbs and possibly the regulator can be done with the cables still connected, especially if you've got long thin fingers.
Hope this helps,
Phil.

I have had the same problem on my ducator 2.0 jtd was stuck at reading 3/4 full all the time. Finally found it to be a trapped wire from the damper unit.
