Well my climate 1.4 tdi has GENUINE Audi thermostat and coolant temp sensor. It does get to 90 but this time of year takes about 15-20 minutes of driving and it does drop back when less engine heat is available. This is I believe perfectly normal as the thermostat STARTS to open at 87 which is near enough the gauge 90. When the engine cools it is obvious only a small drop in temperature will start to close the thermostat and it will be completely closed again at 87. Once the thermostat is closed the radiator will quickly cool down and next to no heat will be available for the cabin heater if required. Audi must has spent considerable time and money when developing the cooling system so doubt much can be done to improve it.
I do not think permanently blocking the air path to the radiator would be beneficial. I do not think a differently rated thermostat would help either. I have said before it would be nice if the Webasto or electric PTC heater could be modified to operate to provide heat in these circumstances.
Perhaps someone can develop a water jacket that fits onto a section of the hotter parts of the exhaust and into or around part of the cooling circuit without being over complicated and failsafe in operation in a similar way the water cooled egr valve works on the BHC and ATL. Certainly less of those owners experience the cooling down and slower warm ups the AMF experiences.
Your thoughts please....
