Peugot 206 HDI electronic failure while driving!

[Burglar]

Hi folks,

Was driving down the A34 last night and all of a sudden the hazards and all other interior lights started flashing on & off quickly along with the central locking.

This stopped and repeated itself 20 mins later. The second time the headlights cutt out!! Turning em on & off while driving brought them back momentarily enough times to get to a parking layby.

Once the car was stationary all electrics seemed to come back but we got towed anyway.

Does this sound like a computer fault or could it be something like bad earth connection?

Any insight much appreciated!
