S60 huge power loss
Hi all, I'm having a issue with my 06 S60 2.5T.. It seems to have lost all power and I can't figure out the problem because I'm not getting any codes. My top speed is about 50 mph on flat ground and can barely pull a hill at 20mph. I've changed the timing belt, fuel filter, spark plugs, and checked turbo tubing for leaks and nothing. Anyone have an idea of what it could be?

did you change the timing belt recently and align to the timing marks or simply use the prior marks? wondering if you could be one notch off... next thing I'm wondering about is fuel pressure. I think your model has the variable pump controlled by the pressure sensor...so it could be the fuel pressure sensor or the control module, so see if you have any engine codes and measure pressure at the fuel rail. Another possible cause is a constriction in the exhaust - ie clogged cat, damaged exhaust pipe or even a failed turbo. If you can get at the o2 sensor and can pop it out and that changes things then you probably have a clogged cat (which can also mean a failed turbo, particularly if you are losing oil) Most likely scenario is the fuel pressure sensor is my guess.
