Got a 2007 XC-70 with 123K, and has been running great.
This week I have had a couple cases where the engine seems to hesitate briefly when pushing the gas, like when coming out of a turn. One time the hesitation was enough for the oil pressure light to flicker. Hooked up my Dice box and VIDA showed no codes. Tank was about 1/2 full, fuel filter was replaced last fall, plugs and timing belt replaced about 18K ago, crank and exhaust cam position sensor replaced about 1.5 years ago, air filter replaced within past year. All were Volvo parts.
Having no codes to point me towards the problem is not making things easy. Any ideas from those that have tracked down a sudden and intermittent hesitation problem? I'm afraid the engine will quit at the worst possible time, and have no idea where to start. I know the dealer (stealer) will just through parts at it since they too will have no codes to guide them.
