2015 Passat with MIL on checked Group 1 Fault Codes found this:

4238 - Engine Coolant Temp Sensor on Radiator Outlet (G83)
P2185 00 [175] - Signal too High

Checked advanced measuring codes for coolant sensors found this:

Code:
IDE00025   Coolant temperature 59 °C
  IDE00194   Coolant temperature at radiator output: specified value 90.0 °C
  IDE01266-ENG57549   Coolant shut-off valve-Bits 0-7 3 
  IDE07724   Coolant temperature at engine outlet: calculated 59.7 °C
  IDE07725   Coolant temp.sens.1 bank 1 at cylinder head: raw value 59.5 °C
  IDE07726   Coolant temp.sens.1 bank 1 at cylinder head: uncnd. voltage 1906.0 mV
  IDE07727   Coolant temp. sensor 1 bank 1 at cylinder head: raw value -40.0 °C
  IDE07728   Coolant temp. sensor 1 bank 1 at cylinder head: uncnd. voltage 4999.8 mV
Replaced coolant temp. sensor at radiator outlet and it appears that fixed the issue. So far.

I am was confused by the similar labeling of the IDE measuring codes. Is this correct?

It appears by the actual temperature/voltage readings that IDE07727 and IDE07728 are for the sensor at the radiator outlet.

Wouldn't be the first time we've seen bugs that produce misleading results in a VW ECU. How long have you had TDIs? Remember how they used to number glow plugs improperly?

Thank you for your reply!
I have owned a tdi since 2004 - a 2001 jetta (which I still drive daily). I recently bought a 2013 Passat tdi and my daughter bought a 2015 Passat tdi. Also have a '97 Geo Tracker that I have a '98 Beetle tdi engine for, but that's been a long term project.
