Car ran rough went into limp mode. Dealer said codes indicate a MAF problem and replaced it. Car ran fine for two months and then the same issue arose, hesitation and limp mode. This time the codes indicted a Throttle Module problem and that was replaced. And now about three months later I am experiencing engine hesitation again with check engine light, I have not had the codes pulled yet. Thus far I have spent $1,600 and the problem has not been resolved.I now question the need for the parts replacement, I think that the codes were false and the dealer hasn't found the solution to the problem.
Check engine light came on. Car would not start. Then car would start, idle, then sputter and die. Had MAF replaced. No change. Had Fuel Pump Module replaced. Then gas gage would not register fuel levels. Had replaced. Now transmission slips and can't accelerate quickly.
S60, Non turbo.

Engine bogs for a few seconds while driving and then picks back up. It is progressivly getting worse and finally cut off while I was driving on the interstate but will not do it when a mechanic is present. I found another website that says it could be a fuel pressure sensor and there is supposed to be a recall but not all S60's are included all though many have the same problem.
We had this problem only owed car a couple of months and this repair was $600. My boss has a volvo and the same thing happened to him.
