If you've been following, I've been having
much fun with my i3.
The latest problem is with the REX:
The first time this happened, I pulled the code in ISTA-D and came out to be a cooling issue. Clearing the code and running the REX again brings the fault back. Dealer eventually replaces the thermostat.
On the same day I pickup the car, I run into the fault again after running the REX for about 20 highway miles. This time, I pull the code and get 115007 "Coolant temperature sensor, signal: too high" with a engine temp about 111C.
Has anyone run into this problem before? I cant imagine it's because of HOLD mode, since a single tank is good for at least 60 miles.
