Next steps - Called XeMODex Friday. Told Matt the whole story and asked if I could send the TBM to them and have it checked out. He explained that some other company felt their toes were being stepped on when XeMODex was building the '04 ETB. Consequently, they quit. At this point they don't have the test stands for these units any more but if they had one left in stock, he would send it to me.

Monday morning the FedEx guy was on our doorstep with a replacement unit. +1 for XeMODeX.

The gears in the old unit had all their teeth. There was a little oil in the electronics chamber and no sign of burnt traces or components. Other than looking under the cover I did not try to disassemble the unit.

Now, if you don't hear from me in the next few days...

BTW, planning ahead I had a look at replacement ECMs. Most of the rebuilders appear to be in England or Europe. volvoecm.com is priced in US dollars, $475 to be exact. There are notes for other years so it would remain to be seen if they are applied to all units or just those years.
