Intermittent buzzing/flash of indicators

Hey all

I'm having an issue with the indicators/turn signals in a 2006 Neuvo with Peugeot Boxer chassis.

After a couple minutes of driving, both indicator lights start turn on for a fraction a second, every 10-20 seconds or so. The turn signal buzzer in the console (near there hazard lights on/off) buzzes briefly, and the indicator lights in the console flash.

Otherwise each of them works as expected. It's just creating an annoying buzzing sound as I'm driving.

I'm guessing it's either a faulty relay or indicator stalk but couldn't find anything similar reported on the forums here...  any suggestions?

Turns out this buzzing happens every four seconds exactly... guessing that it's interference with some other electrical system?  Does this ring a bell for anyone?

Does it have a towbar?

Had you replaced any light bulbs prior to the problem starting ?




Niall

No towbar fitted, and no lights recently changed...

Have you checked to see whether the indicators themselves flash outside, as well as the dash light?

Does it have an aftermarket alarm fitted? It's very common for alarms to be wired into the hazard warning circuit to give an indication when armed/disarmed.

It’s not at all uncommon for a flasher relay to buzz when breaking down. Given the relatively small outlay it may be worth swopping the unit out for a new one, just as a process of elimination.

I can try that for sure. Do you know happen to know where it's located in the Boxer 2016 chassis?

@roopert nope, no alarm fitted :-/
