Thanks DHA the number checked out at the dealer (126-830-07-84) for the replacable temp control unit, its on the way along with two new seals for where the heat exchanger penetrates the reservoir lid. This should help with alcohol evaporation complaints (seal ring part #140-997-06-45). I will see if they fit when they get here. And post the new temp results.
Thank you every one for your input. It is great to have this forum as a resource.
