Just had my 2001 S60 (98k) give up it's throttle body.
Regularly serviced over the last 5 years at a Volvo dealership.
Just back from them on Monday when I'd left it in for wishbones, brake pads and discs, and told them it was dropping revs and lacking power. Got told on picking it up that it had been thoroughly checked and there was loads of power and no issues, and that it 'might be in my head'. So I go on a three day break with it yesterday only for it to pack in miles from any big town after doing about 90 miles. The AA, thankfully, get me to a small town garage and in 15 minutes I'm told the readings are that it's a throttle regulator issue. Takes me 5 hours to get home, taking it gently; it packs in twice on the way back.
I'm absolutely livid.
I've always bought Volvos, my wife's always bought Volvos and her family have always bought Volvos (well, since the 70s and the 240GL). All 5 cars (S60, two v70s and 2 940s) were all (except one of the v70s) going to be traded in over the next 6-12 months for newer versions. Not now. Not ever.
