So bought this Volvo last month. 2014 780 love it. HOWEVERHad a regen issue and a fuel economy issue a week after purchase. Got that fixed.
Now to month 2 and see if anyone has experienced this. It goes in the shop tomorrow when I go home.
First off my engine fault light is on but it's not giving a code. However this is where it gets Wierd. This started 2 days ago. If I turn on my headlights. My tractor ABS light turns on, my TCS light turns on, and my hill start assist light turns on. Also my speedometer drops to 0, my fuel economy gauge drops to zero, and wait for it.....my engines rpm drops to 500 rpm and loses all power. I have to pull over and restart the truck and it resets. But if I turn on my head lights or parking lights even, it does it again. I thought it may be the trailer so I disconnected the pigtail and it's still doing it.
Sooo.. Has anyone ever experienced anything like this? I am hoping this is the last of my new truck bugs... Keeping fingers crossed. Other than that this truck is absolutely amazing.
