The second was the "Dieselgate" scandal that broke out in 2015. In June 2018, the Federal Motor Agency KBA ordered the recall of Audi models, after a new model had been discovered. "Illegal Software" which can distort the emission levels of gaseous pollutants and in particular of NOx. If the previous callbacks are three- and four-cylinder EA189 TDI engines (manufactured between 2008 and 2015), these are the models equipped with 3.0 V6 TDI and meeting the Euro 6 standard.
Greedy in AdBlue
Officially, Audi announces a simple reprogramming of the engine control unit without giving any further details. If we read the "23X6 Quality Control Measure" that we sent to the dealers and that we received, the update will also be accompanied by a Reprogramming the computer for automatic transmission intends to adjust the pass points of the reports. We also learn that in certain variants the NOx transmitter or lambda probe needs to be replaced. If Audi claims that the technical changes have no effect on fuel consumption and vehicle behavior, this is not the case for AdBlue consumption.
The affected models:
A6 and A7 3.0 TDI 211, 218 and 272 hp (2015-2018)
A6 and A7 3.0 biturbo 320 and 326 hp (2015-2018)
A8 3.0 TDI 211, 258 and 262 hp (2014-2017)
Q5 3.0 TDI 250 and 258 hp (2014-2017)
SQ5 TDI of 313, 326 and 340 hp (2015-2017)
This can increase depending on the driving profile, but especially after a reprogramming, in which more urea is to be injected to reduce NOx emissions. Bad news for the wallet of the concerned owner. As compensation Audi offers these four refueling in AdBlue The first occurs when the recall is performed and the other three as needed. Note that each refueling is recorded in a designated certificate.
Audi has determined that this is possible for the A6, A7 and Q7 in addition to the NOx-related anomaliesa tank error AdBlue, for example, with water, is not recognized. In other words, the German mark does not meet the standard imposed on all manufacturers and serves to detect user's filling errors. Currently, the update for the Q7 3.0 TDI is not available.
