My 2003 C70 with103,000 miles has failed inspection.

What is your question?

I have been to the inspection station 3 times and have failed each time because all of my emissions components were "unsupported". I brought it to a shop,not Volvo,and they told methat they were unable to communicate with the Ecu. There is no check engine light on. They suggested I go to Volvo and have the Ecu re-flashed. What do you think?
