35D DEF Tank Level Sensor Issue

[Ozer]

So some people passed around my email to the EPA, i was CCed in the emails and Mr Ross got back to me saying
"I looked further into the DEF tank issue and have found that BMW plans to replace defective tanks with a more robust version. You should check with your dealer to find out if you are covered by this plan."

He said he doesn't know timeliness but said ask couple dealers.

Yea, this issue is likely just warming up. The DEF system is part of the Diesel Emission system and I believe there are FAR to many premature failures.

I am sure there is more to come.

Can people ask their dealers as they go in for services so we get to hear from bunch of different dealers as to whats coming down the pipe, if anything?

It would be great if they issued a recall and didnt put 100k miles as the cut off for these tanks. I'd like to get mine fixed versus going the downpipe/tune rout for financial reasons.

My Active tank has a failed temp sensor too. Originally a NJ car but moved down to TX last year and my CEL came on after few weeks. Could have been covered by the Emission warranty 7yr/70K miles. Never paid too much attention to it. Fast forward to last month, dealer told me to SCR active tank temp sensor is bad and gave me $1800 estimate.

Called BMWNA if somehow they can help me, they said no.

Email sent to EPA.... We'll see...

Its one thing to give you a $1800 estimate, however, did anyone tell you how long the repair would take??

From my last understanding the tanks were on National Back Order and it was unclear when they would become available.

Seems the entire DEF system is a bit fragile and they are overall having failures at a very high rate.

Is there a mandatory emission testing in Texas?

.

Driving around a year or there abouts with the CEL?


EPA will do nothing.

Save your receipts- if BMW recalls the parts later you MIGHT get reimbursed.

Just had my passive tank replaced under warranty and picked up the vehicle this weekend. Actually looks like both the active and passive tanks are relatively easy to access. Active is right behind the front bumper on the passenger side which means bumper removal which isn't too bad. As for the passive tank, there's an under panel cover that covers it aside from that it looks relatively accessible.

Accessing the tanks isnt the problem, getting replacements and the cost of them is the problem. The bigger problem is the stupid integration of the sensor into the tank, nice job BMW engineers

I overfilled both my tanks couple moths ago and been getting codes for both tanks. Im assuming now that the level went down, the codes havent been back. So im gonna say dont overfill the tanks and see if that gets rid of the codes (for those who have codes on )

Reminds me of the sulev fuel tank issues on the E46 models. You would think BMW engineers would have thought non serviceable tanks that contain sensors would lead to issues down the road, clearly they still haven't learned.
