Asked by Aug 08, 2016 at 10:38 AM about the 2011 BMW X5 xDrive35d

Question type: Maintenance & Repair

I had the following Nix sensor problem.

6 month ago, the front NOx sensor had problem, and made the engine locked
deadly, so I had to change the sensor and the DDE computer. After the DDE
and the front sensor changed, the rear sensor had problem, and set 330KM to
locked the car again. I changed the rear sensor, and tried to do the procedure
to release the engine lock code. After checking the car, no problem on the
sensors, no problem on the SCR converter, but only the locked warning is still
there. Please help how I can do with this problem.

Why the change of the DDE for a simple nox sensor issue? Has the system been scanned with a OSS tool what are the codes? SCR (Selective Catalytic Reduction) what happen after you tried to reset?

I have a PDF testing report after replacing the DDE, but I do not how to upload here. After replacing the 2nd sensor, the waring information "Incorrect Exhaust Fluid detected. 106 miles to No Start" is still there, and cannot be cleared.

Before replacing the 2nd sensor, the Code is as following: 0041F9 SCR System: System error and poor urea/water mixture quality detected 88730 Miles 004583 4583 Message 88705 Miles 004585 4585 Message 88705 Miles 004748 SCR system, warning and deactivation scenario: Warning Stage 2 88730 Miles 00474C SCR system, warning and deactivation scenario: Warning level 1 88730 Miles 004873 4873 Exhaust gas recirculation cooling, plausibility 88490 Miles 0049F1 DDE: CAS Bus D 88705 Miles

At present, there are only two error code left: 00474C SCR system, warning and deactivation scenario: Warning level 1 004873 4873 Exhaust gas recirculation cooling, plausibility

All the sensors were replaced, DDE replaced, total cost over $5500! But still have the above problem. Please help me. I appreciate!
