Technical Bloody ducato strikes again

[Nickyboy123]

Iam stuck people I have a 2018 ducato minibus the reverse lights stay on until you remove a 7.5amp fuse in the underbonnet fuse box once put back the vehicles perfect reverse lights operate normally for 3 or 4 times then there back on.the reverse switch is fine.being a minibus before it's returned to service it has to function 100%.I have even disconnected the reversing buzzer no change.the vehicle has had water damage.have checked the underbonnet relays etc along with the fuses that are situated inside .all the rear lamp connections are good any ideas?

Is it likely a relay contact is sticking, even assuming it uses a relay on reversing light circuit on that model?
When you say it has had "water damage" , do you mean as in flood and if so how deep?
Generally after flood damage insurance companies tend to write the vehicle off as the water corrodes all the wiring joints and anything else it can get too, it may work for a while, but the damage continues.

Hi mate the driver was attempting to drive through flooded roads.dont think it was too bad no water in air intake etc but had left the bonnet up for 3hrs.have swapped out the relays with its sister bus and all appears well

I have changed my reverse gear switch on top of gearbox several times, I suffers from the rain water dripping onto it from scuttle, it sounds to me something that would stick on due to corrosion?

Found the issue in the the end the ecu has been drowned.ran out of ideas opened the ecu and you could actually see the water inside surprised it actually ran due to the amount of moisture inside

I keep saying that it is rarely a relay that is the root cause.

It was probably the position of the relays diverting the water to the ecu.

Maybe Op should tell his driver the "Plimsoll Line"used when going through puddles needs to be lowered.

Our driver has been told.got to be honest tho the ducatos we have are the most unreliable vehicles we have.got 3 with delivery milage stuck in dealers with steering angle sensor faults the 10yr old Mercedes with 800 000 miles still good to go

My most reliable vehicles and easy to work on were pre ECU Iveco Daily 2.8s though eventually the body's rusted off the chassis's, you can see why most got exported, bit like Nissan Cabstars etc.
