Indicator/Hazard light problem, X250 (1 Viewer)

[dally]

Hi folks,
We're on our second 3litre Ducato and we have had the same problem on both. (Both 2007 models)

All the indicators are working fine, all bulbs work and they all flash at the correct speed from the outside in whatever mode selected. I.E. left, right or hazards.

However, on the dash, used independently, left is fine but using the right hand indicator or hazards then the dashboard shows a bulb failure (even tho there isn't one) and the dashboard lights flash and click at twice the normal speed. I have an MOT coming up so need to fix it, I'm assuming it may be an MOT fail.

Cured it the first time by running a live wire from the front right indicator to the rear right but want to solve it properly on this motorhome.

Must be fairly common for it to happen on two different vans but I can't find anything about it. Can anyone point me in the right direction please?

Many thanks,
Dally

it is normally an earth fault on the rear light cluster wiring due to corrosion

Other thing to check
Have you changed a door mirror?
There are two different wattage of bulbs
If you fit the wrong one you get the fault message
