Happy new year all.
I am having a nightmare of a problem with my 2014 Aventador Roadster with start stop for over a year now.
It all started with the car not starting when I press on the start button. AlI I heard was a
‘Click’ and dash had ‘start stop fault. System not ready’.
Installed new battery, new super capacitor and new trickle charger and every time we thought the problem was cured, it comes back again.
I tried giving the car a start up yesterday and the problem came back. I’m at my wits end as to what the root cause of the problem is.
if I remove the positive (red) cable on the supercapacitor that goes to the starter motor and connect it directly to the positive terminal of the battery, the car fires up. (By doing this, it is the car battery that starts the starter motor rather than the capacitor). This surely proves my starter motor is ok?
We have checked all the wiring, clean all electrical contacts etc….and the problem still persists.
Any help or advise us greatly appreciated. Might need to send it to the dealer for a proper diagnostic plug in??
