Update on this FYI.
Took the car to Volvo who was very helpful. Codes had not returned but they told me that the front oxygen sensor was bad along w the heating element in the intake hose that goes into the turbo. ETM checkied out ok. Replaced the sensor myself w a Bosch one from Rock Auto and it seems to have done the trick. Picked up a used hose but have not put that on yet.
