Hi Guys,

New to the forum and looking for some assistance

We have a 2010 B180 BlueE which is a Manual

Having an issue with the Reverse Lights, I've check the bulbs and fuse which are fine, my father in-law replaced the Reserve Light Switch, he said that it was disconnected previously but went on to replace the switch anyway. Since its been changed the reverse lights constantly stay on

Hope you can help

Charan

Hi, yes that's right when the switch is disconnected the lights go off. When you say a problem inside the gearbox would this require the gearbox to be removed?

Ok , its stands to reason if the switch wss replaced with new then the only answer can be inside the box itself ! Ive never heard of any manual car with this issue , its usually the switch , may i suggest you triple check the switch for fitment / operation before doing anything else

My stab in the dark is a wiring fault.
Wire rubbed through somewhere and going to earth.
That's assuming its an earth to the switch and not a live.
Much like a fuel sender unit wire when earthed reads a full tank all the time...
