Diagnosis: Replace Power Control Unit

Think diagnostic interface from the back
I got a prompt visit this morning from Think North America's service manager (I am not really certain what his title is, sorry), the day after my wife and I returned from vacation.  He was able to confirm that our second Think needs its PCU replaced.

They could fly someone down here but I would prefer to learn something about the car, so I am arranging to use a local shop with experience in high voltage hybrids.  We need to lift the car and disconnect the high voltage cables, then evacuate the R134a and remove the air conditioning compressor and condenser to get at the PCU.

While parts for the car are plentiful, I would like to purchase the diagnostic interface, pictured above.  At the moment these are not plentiful in the US, I am told.  The service manager, who is in regular contact with engineering in Munich (he was on a call with them before coming to my home) will let me know when they are available.  The price is above $1000 and the software license which provides updates regularly might be even more, but perhaps I can get an old static copy with some minor bugs.  Since I am far away from any authorized service, I would like to be equipped to diagnose problems in the future after the warranty runs out.

Think Ox concept from Skeie Industridesign Vestfold

I was not able to gather much in the way of news about the future direction of Think, except that the new model will likely be more along the lines of the four door concept than the previous two seat models.
