Once we find a solution for adding external active tank temp sensor replace rate will go down 60-70% from whom is interested in DIY. Level sensor failures, like OPs, are much rare. But there must be a way to emulate this signal.
Last resort would be to disable the DEF in DDE(VW did it in a corporate level  ) or disable the DEF related codes. These solution will come soon as more and more diesels are going out of warranty and there will be a real demand. In the same way as replacing the dreaded N62 coolant transfer pipe was $6-8k years ago and now is offered for under a grand in many places. |
I proactively installed a
Bimmer Fix | Coolant Pipe Repair System coolant sleeve in my N62 when I replaced the water pump a few weeks ago for $200.
So hopefully I will not have to deal with a leaking coolant transfer pipe in my N62 during my ownership!
But there seems like a market will quickly pop up for DEF tank solutions.
Is there a transfer pump between the passive and active tank? I did not see one listed, but I did not spend a lot of time looking at the system since I do not have a Diesel. But I was just curious as to what/how the temp sensor functions and if there was a work around other than replacing the entire tank at great expense.
