Love this car!

New ETM this fall. Started having loss of power on acceleration the last few weeks.
I drive a lot for work.
Was going to bring car to Gengras Volvo, East Hartford Ct. Great Dealer!
Instead, cleaned ETM. Runs fine now. Gengras said that its under warrantee if this continues.
Little concerned that it needs cleaning after only 12k miles.

And this is the new Morrelli model.

Good Luck.

The throttle body on these cars get dirty very fast.
They should be cleaned atleast every 20,000 miles.

Your crankcase ventilation system maybe clogged or partially clogged and is contributing to the rapid build up on the throttle bore. The oil trap and/or the banjo fitting under the intake manifold and the hose leading to the oil trap may be clogged and in need of a cleaning. From what I understand the manufacturer will not continue to pay to have this cleaned out everytime this may occur. After performing this service it may be a good idea to have the engine oil flushed and begin using a quality full synthetic motor oil which seems to really help out turbo engines from oil sludging.
