General Injection Warning Light Constantly On

[moonshine]

I own an A Class motorhome built on a FIAT Ducato 2.8JTD common rail engine base. The vehicle was built in 2001 and I imported it directly from Germany.

I have recently had the vehicle given a full service and put through the MOT at a large commercial vehicle company. On driving away I noticed that the fuel injection warning light remained on constantly. The service company were unable to immediately solve the problem and arranged for me to take the motorhome to the local FIAT main dealer. They tried to connect the vehicle to their FIAT computer, but after an hour and a half they said they had been unable to communicate with the Electronic Control Unit. Late on a Friday afternoon they didn’t have any other immediate suggestions. Today they are talking about removing and disconnecting the ECU before reconnecting in the hope that the error message will be cleared.

I’m really miffed as the vehicle had gone in for a service and MOT and was released with a problem that didn’t exist before. Now nobody seems clued up as to how to clear the problem. I would like to believe that it is a simple fault caused during the servicing and easily resolved. But at the moment I’m not confident that the people I’m dealing with are that concerned or have any answers. Does anybody out there have any helpful comments?

I think only thing that u can do in this case which is checking the wires from the control to all the system maybe some water droped on the wires and make this fault just take ur time in checking the wires and dont be hurry.

This happened to me last month on my way to the eurotunnel, called out the AA who said the fault did not show up on their OBDII reader therefore could not fix it. Carried on to France firing intermittently on three cylinders and red fuel injection light on dash showing.
Called into a Fiat garage in a small village. the mechanic on hearing the engine said "This is a common problem with Ducato" He took off the plate covering the fuel injectors then he loosend the clamp holding the injector wires and gently pulled the wires towards the injectors to give them more slack, indicating that Fiat had made the wires too short. He then tightened the clamp, took the connection wire leading to No.4 fuel injector gave it a spray of something, replaced it on No4 fuel injector. replaced cover and that was it. Cost 29 euros. I have since travelled 900 miles to my holiday destination without a repeat of my earlier problem.
Tools used: two spanners to undo the bracket and a spray of some electrical cleaner. Time taken 20 minutes.

Common problem lots of people have had to replace the number 4 connector. Even loosening off all the clamps its hard to get a few mm slack!
