BMW Diesel-Sofware: Official Statement to N57-topic

The news came yesterday, like a clap of thunder, but with a little closer inspection, the BMW Diesel, the Software issue is a completely different than other manufacturers. Because the more Details come to light, the clearer it becomes: The subject has a incredibly bad Timing and is rated in the Public with some certainty similar to that of the exhaust gas affair at Volkswagen, the backgrounds and effects are completely different.

First of all, it is to be noted that, in contrast to Diesel-issue with other brands, not hundreds of thousands or even millions of vehicles are affected, but only is 11,700 vehicles with the built-Triturbo-Diesel. This is 11,700 vehicles are distributed on four niche models, with the 381-HP version of the inline six-cylinder diesel N57 3.0 litre engine: BMW M550d sedan and Touring and the BMW 750d with short and long wheelbase.

The same engine in the BMW X5 M50d and X6 M50d is not affected, is, paradoxically, the trigger of the problem. Because in the SUV models, the X5 and the X6 comes in addition to the NOx storage catalytic Converter, also an exhaust-gas aftertreatment with AdBlue injection. This was in M550d and 750d is not required, all of the valid limits. Human error led to the engine-used Software for the X5 M50d and X6 M50d erroneously for M550d (F10, F11) and 750d (F01, F02), which eventually led to problems with the cleaning of exhaust gases, because the Software behind the AdBlue-injection has not been installed in the Non-SUV and therefore could not work.

It was discovered the Problem is also not from the KBA in-house, as the mirror told originally. Rather, BMW is noticed in internal testing, that some specimens of the M550d and 750d in each of the workshops have mistakenly received the wrong Software Updates. It was not, therefore, an area-wide action and, therefore, also not all of the M550d and 750 are affected. BMW informed the press about the issue and is planning a recall of all models, in order to have again all of the M550d and 75od with the particular Software on the road.

Of a nationwide, or even deliberate Manipulation, may not be in these circumstances, definitely. Nevertheless, it is predictable that many of the less technically interested, or only superficially informed people are scissors, the BMW Group now with the other car manufacturers have tampered with the exhaust gas cleaning with hundreds of thousands of Diesel Cars aware of a comb.

The official Statement from BMW in full length:

BMW Group is planning a recall for the correction of incorrectly assigned to Software Version

Munich. The BMW Group has found in internal testing that a properly-developed Software has been assigned to a few that were not suitable model versions by mistake. The BMW Group has informed the relevant authorities immediately. The corresponding Software has been developed for vehicles with a combination system comprising SCR and NOx storage catalytic Converter correctly.
Mistakenly, this Software was used in model versions, the active exhaust is after – treatment exclusively via a NOx storage catalyst. These models were equipped at the time of their initial registration at the start of series production in 2012, with a correct Software.
Therefore, the BMW Group is 11,700 vehicles is planning to call back. For these vehicles will be deployed after approval by the competent authorities of a corrected Software.
Are the loaders affected niche engines of the already-leaked model-generation of the BMW 5 series and 7 series from the years 2012 to 2017, with the high-performance diesel engine N57B30S1 with three turbo. It is in the Individual:

  • BMW M550d xDrive sedan (production 03/2012-10/2016)
  • BMW M550d xDrive Touring (production 03/2012-02/2017)
  • BMW 750d xDrive (production 07/2012-06/2015)
  • BMW 750Ld xDrive (production 07/2012-06/2015)

All further steps are carried out in close coordination with the competent authorities.
