update.

My car is still under an extended warranty, so I took it to the dealer. Here is what they found and replaced under warranty:

-first the obvious final stage resistor
-leaky high side service port

I was also hearing a groaning noise if I mashed the gas going about 55 mph and let off the gas quickly. They determined that the IHKA control unit was faulty. I am pretty sure it has something to do with the heating regulation.

All in all another $1,300 in warranty repairs, which brings my total to $6,000 +/- in warranty repairs in a year and a half of ownership and about 25,000 miles. Not so good. Needless to say the end of the warranty is nearing and I am starting to consider letting go of her shorty after.
