I have had this s80for about 5 months, it is a 2001 with 73000 miles on it. We've had the radiator fan replaced, the transmission Rebuilt( clutch for 3&4 went out ), now it running rough and surging at mid power and does not develop full power. Also the nearest volvo dealer is 3hrs. away in Albuquerque>

 

Did you have the Recall software done at the Dealer yet?

If not you should have that done.

 

BINGO
