Hello everyone.

I am having electrical problems with my Xsara Picasso, 2005 1.6, 8v, manual, petrol. The dipped beam has stopped working; I have checked all the fuses, tested with a multi-meter, including the maxi fuses under the bonnet fuse box. Replaced the bulbs and even replaced the expensive Com Unit as I had this happen on a previous Xsara Picasso and changing the Com Unit solved the problem there. There is no power getting to the bulb connector for the dipped side, side lights work and the main beam works. All other electrical equipment is working fine. I have cleaned the under bonnet earth wires which are bolted each side of the inner wing but still the dipped beam will not work. All the rear lights are illuminated when the stalk switch is turned on.

 

I connected Lexia and could not find any fault codes, switch value changes when turning the switch on and off so Lexia is connecting correctly. Instrument display illuminates when switching through side, dipped and main beam. I am wondering if there is a dirty connection somewhere or an earth that I have not located.

 

A very annoying problem for sure.

 

I would greatly appreciate your opinion.

 

Thank you.

Then my best guess is back to the comms unit.
