The odometer on my 850 just died. I suspect the odometer gear gave up the ghost. I called the dealer and they said Volvo now has an improved gear and they will install it for 0. I called my mechanic and he said he could install a new odometer since repair parts are unobtainable. When I told him that Volvo distributes a repair gear, he said they could do it for about 0. I suspect I could do this myself as I did it once on a 240 but, at 62 years of age, life is too short to go through all that again. Chuck Fiedler Nothing but Volvo since 1974
