Outcome of hazard light problem

OK so the Renault dealer has had my Laguna now for a bout a week - the outcome of a lot of hard work by them to get to the bottom of the problem is....... the alarm system. Apparently there is a fault with it that standard diagnostics didnt pick up and it wasnt until an attempt to replace the suspected UCH that the actual problem became apparent.
Cost for replacement unit + fit - 350+ ....ouch...

Mmmm dont thinks so ... mine were triggered when brake assistance was activated ... so does the same system on the Volvo ....

I'd guess its a faulty sensor or an earth problem.

hope it helps

Why is it the older I get .... the better I think I was ?
