We have an '05 S60 2.5T and I just spent the day doing a full major service, including the timing belt and water pump.

Everything went relatively well (though there was some colorful language getting the new serpentine belt on).

After about 20 miles, the check engine light came on. I pulled codes, and got P0017 (cam/crank correlation) and P0027 (exhaust valve range/performance). This makes me think think that I might have mistimed the engine. In particular, this seems like the exhaust cam might be off by a tooth.

Clearly I need to pull it apart again and verify the timing, but the marks on this car are horrible. I've attached a photo of the crank pulley and oil pump. Is the timing mark supposed to be that little tab on the left side of the L-shaped boss on the oil pump?

[the image got posted rotated 90 degrees. "up" is now the left side of the image, and the tab I'm referring to is at the bottom of the frame]

As to the camshafts, the only think I found that made any sense as a timing mark was a tiny punch mark on the inner radius of the rim of the cam pulley.

I'm off to search the web for more photos, but any wisdom would be appreciated.

 

Looking at the pic rotated the mark on the oil pump is the part sticking out. Also from the pic looking at it rotated if you were go turn it down one tooth and go into the valley that should be lined up like it should be.

 

Thanks for the confirmation, tech.

I pulled the covers off today and indeed the exhaust cam was retarded by 1 tooth. I re-timed the motor, and all is now well.

I did learn that if you start the car on the lift, it will get really upset. Brake Failure: Stop Safely, Anti-Skid Maintenance Required, etc. Load up the suspension and reboot it, and the errors all go away.

 

Congrats
