Hi Guys, van just cut out today, pulling hard along some straight road, (late for work) crested a hill and the engine died. Felt like my passat when I was having fuel starvation due to bio fuel, except it just died compleatley.
I'm planning to pull down the fuel tank and clean out whatever is in there, local garage said that the pump in there is prob shot and should be replaced, does anyone have a quick/easy way of telling how well the pump is running???
Also we towed the van ( good solid T4 Syncro - never broke down... )and she started, even though no amount of cranking on the key would get her running??? She seems to be running fine since? Any ideas where to start, nothing I've seen in the forums seems to describe this so far???
Cheers Broken transporter

Ok, just removed the radio there, something else i'm working on. started the van to check if she was still happy. She fired up first time but with fuel light on, even though half a tank, and best of all, smoke started to billow out from the double din where the radio was. Now feeling super happy, my obd2 cable dosnt want to work either, says van is not compatible... Class, I love it.

And a new funny one, the fuel guage works fine as the van pre heats, but about 20 sec after she starts up the cooling fan comes on ( even though the engine is cold ) and the fuel guage switches off, does the fuel guage going into empty position indicate a loss of power to the tank pump???
Ps, no smoke anymore???

On the smoke, my chinese obd cable which dosnt seem to work was plugged into the diagnostic port that time I started the van. The smoke was almost immediate so I killed the ignition, no smoke on subsequent startups. I've pulled off all the easily removable bits of dash and no sign of burning or melting, either its not that bad ( fingers crossed ) or its buried deep in behind the dash clocks, more likely.
Whats stranger is that their is another 2.5 130 at work, same year with similar problems. It started acting up about 2 months ago, fuel starvation issues. The mechanic has pretty much stripped out everything from the fuel tank to the injector pump, problem not sorted...Fuel guage not working either.
Does anyone know if the fuel pump/guage and the cooling fan share any common wiring, maybe under my seat, near the dodgey central locking thingy???

I've got similar problems with a van i'm looking at.

fault code read the dash and it says tank sender and ambient temp sensor on bumper open circuit.

the ambient sensor makes the cooling fans come on.

They share an earth wire but as far as i can tell looking at the diagrams it is just earthed back to the cluster.

I've read someone had a similar problem on a passat and just earthed the sensor earth wire out permanently and it cured it but i'd like to know what the real problem is.

I dug out that ambient temp sensor this evening, its working fine. Dug out another sensor on bottom nearside of radiator, its fine also...gonna have to chase another ghost, any ideas guys and girls. Take out seats and pull up cab mat is next I think, check as much of the harness as I can under there...

Yo - Mechanic says, injector 5 is down - via diagnostic. Hence the van is a bit lumpy at low revs. The diesel in the fuel filer is like watery grey tea, fuel filer was changed 25k ish kilometers ago. And that I have an undiagnosed cambia fault code - P1855.
Action???
New filter, wash tank.
Check injector after that, change as necessary.
Fault code???
He had no opinion on the irregular fuel guage operation, or the continuous cooling fan operation - hopefully that's the fault code. Any ideas guys and girls???
