Fast and easy: these are the 3 solutions that apply to Volkswagen TDI engines affected
Both the Volkswagen Group, as the bulk of customers whose diesel engines were affected by the fraud of the TDI today can breathe a little easier. Volkswagen has just announced the technical changes affected demand their diesel engines to comply with regulations to legalize their status. And as we have known, those changes will be simpler, and less traumatic for customers than expected. The only engine that require physical modifications - and must not involve more than one hour of work - is the 1.6 TDI. The other engines could exceed European standards with a simple solution as software reprogramming the ECU. What are these solutions? What impact can have on the customer?
2.0 TDI engine (EA 189 family):
According to Volkswagen, the group affected models using block four-cylinder and two liters only require a software update to meet European standards for which they were approved. That means enough work half an hour to complete. Volkswagen did not clarify whether that will entail reprogramming some alteration in consumption or performance. In any case, it seems that the solution will involve a major change in engine performance.
1.6 TDI engine (EA 189 family):
This engine will be the only requiring physical modification, in addition to the re-programming of the ECU. According Volkswagen, it suffices mesh installed behind the air filter, and interposed before measuring air pressure, and engine intake entrance to more accurately measure the air inlet and improve the quality of combustion. This improvement of the quality of combustion would be enough to get NOx emissions from these engines comply with European standards. And a priori not imply variations in performance. The review of this engine will require less than one hour of work.
1.2 TDI engine (EA 189 family):
Although the solution for engines 1.6 TDI and 2.0 TDI already been found, delivered and verified by the German federal authorities, the 1.2 TDI engine is still to be confirmed that such a solution. According to Volkswagen, it looks like simply a software upgrade in any case, this information will be confirmed in a few days, before the end of November.
As recently announced Volkswagen, solutions for TDI engines EA 189 family were simpler than we would have expected. In any case, do not forget that we are talking about solutions for Europe. In the United States they are still working to find probably more complex and traumatic than advertised in Europe, solutions both NOx emission limits are also stricter.
Definitely, these reports also reinforce the hypothesis that economies of scale and boost obsession Volkswagen diesel in the US, Volkswagen have led to the current situation. If the solutions applicable in Europe are so simple, it is clear that Volkswagen could have gotten their engines comply with European standards without any trick.
Calls to review will begin in January 2016. Volkswagen will pay all costs and discomforts that requires the recall, including facilitating transfer to customer workshops, or replacement car in case you require it. In any case, in view of the announcement by Volkswagen, we must not forget that we are talking about minor revisions, which in no case will require more than one hour of work.
