Hi, welcome to the forum :cheesy:

That sounds like your Comms unit playing up.

I had the same issue ( terrifying at night..! ) and initially I set the lights to DRL using the Peugeot diagnostic tool, but after a while I resorted to sending the Comms unit away to be repaired - cost £30 at the time...

Look on eBay for Comms unit repairs for an idea of price.

Basically the rotary contacts on the end of the stalk wear away over time so the connection is very hit and miss.
