Hi,

I bought a 2000 volvo s80 t6, six months ago it has about 80,000 km on it. Today I received a message saying "performance reduced". Now I did feel the wheel shake alot when I was on the highway in between 100km/ph - 120km/ph. After I came home, turned off the car and turned it back on, and reved it , the message disappeared. I don't know what this means. Anyone input from anyone would be soooo helpful.

 

That means there is trouble codes in the engine module.

 

this sounds serious...should i have it checked immediately? or can it wait since the message has disappeared??

 

I would get it checked when you can.
Since it went away most likely it is an intermitant fault. But still have the codes pulled.
