Active tank temp plausability
2009 E70 X5 35D

Working on trying to decipher the root cause of 2 codes I am getting.


Faultcode: (0x46F9) Reductant active tank temperature sensor signal

Faultcode: (0x4D32) Reductant active tank temperature sensor, plausibility

I have removed the injector nozzle and it was fairly clean only a little crystallization around the actual nozzle...filled def fluid reservoirs.

Any advice?

I looked a a good thread on replacing the seals in the active tank..but thre link to the parts connection was showing not available anymore.

Help Appreciated.

I have the same codes, brought it to the dealer and they replaced the active tank for free under goodwill 10 years 120K miles extended warranty.

CA is not California?



Anyway, there are a ton of posts on how to deal with your failed temp sensor in the active tank- from a resistor hack to a VW retrofit part that will fix it.
