02 S80 check engine
Just bought this (90K), mechanic who sold it to me had put in a tranny, timing belt and water pump. Check engine light came on, scanner says Overhead ehaust cam timing... Seller will certainly look at it for me, but do I have any reason to worry, should I get this looked at immediately. thanks

Often when people work on these Volvo motors that dont know them very well mess up the timing. They dont understand how the variable valve timing unit works. The result can be that all the timing marks line up, but the timing still appears to be out. It wont cause any damage, but you might experience loss of peformance, worse fuel economy and bad starting until its fixed.
This thread has some info on setting the VVT unit correctly: https://volvoforums.com/forum/volvo-s80-18/timing-gear-camshaft-position-49525/

P0014: Most likely the VVT was set incorrectly. After that it could be a sludged up VVT solenoid or its not happy with the viscosity of the oil in the motor. My money is on the VVT not being set right
The other two codes are cat efficiency. The T6 has two cats and four O2 sensors. Looks like both postcat (aka downstream) O2 sensors are faulty or the cats are not working and need to be removed or replaced. Removing them wont get rid of the code of course, but its cheaper than replacing them.

You may have an expensive cat converter repair on the horizon though. $200/cat easy + labor.
Bet the P0014 taken care of as it will affect peformance and gas mileage.
