At night when I have the white front lights on plus red rear lights. I do not know why the indicator lights both right and left either just come for a few flashes then stop. Sometimes the indicator lights will not work at all. There is no problem during daylight hours. Sometimes the main white front lights turn off as well.
I suspect a faulty BSI,
Body systems interface,
Basically a box that controls all the electrics.
It needs a "Global scan" done with Peugeots diagnostic system.
Thank you for answering my question I am grateful. However how much do you reckon roughly it will cost to have the lights put right by doing a diagnostic check.
