Coolant Temp Sensor(G83) & Tiptronic Switch (F189):

[drew62]

I pulled the following codes:

17698 - Coolant Temp Sensor at Radiator Outlet (G83): Signal too Small
P1290 - 002 - Lower Limit Exceeded - Intermittent

18161 - Tiptronic Switch (F189): Implausible Signal
P1753 - 35-10 - - - Intermittent



Anybody have experience with these problems or come accross any DIY or part #s? I looked around both here and AW for each fault code, but all i can find are bits and pieces of explanations...

17698- Coolant temp sensor needs to be replaced. I am not sure on the other sorry. I just found the same fault codes and I will be replacing this week I am sure you are good by now but if not, hit me and Casa and I will relay what worked the easiest. For right now i noticed when looking down into the engine bay it was on the bottom right part of the radiator, easily accessible after removing the belly pan. I can still drive but I hate its idling disposition right now. Peace.
