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.

Where are you located?
I am north of the border :)

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.

Good catch!

Glad I don't live any farther north.:D
