Reprogram the engine Volkswagen TDI can have side effects in half of cases


On a previous occasion we explain whether it was appropriate to update the diesel engines of the Volkswagen Group with high emissions of oxides of nitrogen (NOx) with programming fraudulent, the TDI CR EA189 (Euro 5) 1.2, 1.6, and 2.0. Various european institutions, such as the KBA German, said there was no risk.

however, when we asked the owners of the thing changes. It is not difficult to find testimonies of owners of any Volkswagen, SEAT, Skoda or Audi has noticed that something goes wrong after the intervention of the official service to reduce the toxic emissions from the exhaust (or it was meant to). Now we can talk about it with a more empirical basis.

The OCU Spanish has participated in a study at the european level (Euroconsumer) to ask the owners of these cars if you have noticed side effects. According to the laws of statistics, 10,500 people at the european level are very representative with respect to more than 8 million people affected, the same as 2,000 in Spain. The conclusion is that about half of the respondents have noticed these side effects, and the fourth part has had to go after to workshop or will have to go soon.

half of The reprogramming has no side effects, does not affect all engines updated


Responses to the question “have You reviewed the software?”

This chart is very revealing. Only one-fifth of respondents in Spain have taken the car to perform official intervention, a percentage similar to that is what you are thinking. The majority has not done not rely on, despite the fact that the DGT encouraged to do so, and because in Spain is not mandatory for the owners (p. e. in Germany itself, or lose the tuition).

Recall that the manufacturer in theory it only reprograms the ecu engine 1.2 TDI, 1.6 TDI and 2.0 TDI, and in the case of the 1.6 TDI installed a piece in the intake duct in order to better measure the flow of air. That is to say, the mechanical’t touch delicate parts related to the injection and treatment of exhaust, but the ones that do the update seen failures in almost half of the cases.

is Not guaranteed the actual reduction of emissions of NOx, which is what this is about

According to Volkswagen Group Spain Distribution, the Spanish branch of VAG Group in our country were almost 700,000 of those affected. Nearly half are brand Volkswagen, are typically Golf, but also tend to be Tiguan, Polo, Passat, Audi A4 and Seat Ibiza. About three of every four were enrolled between 2010 and 2013.


Answers to the question: “what did you Notice about changes in the car after the fix?”

According to the respondents, the side effects are noticed fast, and the first failure may come in a month. Certainly, they are breakdowns typical in modern diesel engines, but I have the hypothesis that reprogramming forward what it is-almost always – inevitable. Diesel engines already are not “indestructible”, but speaking in silver are not the vital components and all auxiliary.

In other words, no engine is “broken”, but it can go worse than before

The later repair costs, on average of 1,160 euros to the owners of Spanish who have had some damage (13%) after the update. According to the OCU, the various brands are admitting to at the grantee level who is at fault in 30% without charge to the customer, and in 41% of cases did not see the relationship but were paid partially or without charge to the customer. A small portion of the dealers (4%) washes his hands and refuses to take responsibility.

and consumer organizations and various law firms recommended retain all documentation relevant to these updates for a later claim in the courts. If the updates are precicipando or causing mechanical breakdowns, even though they are not generalized (77% do not declare to have needed to go to workshop) is a must compensation.


Respuuestas to the question: “do Repairs after the change?”

I have been told many times that in Europe there will be no compensation to the owners unless we win in the courts. In the united States homeowners can choose between repair (when available) or return the vehicle (s) by counting its value before the scandal -September 2015-, always a compensation.

The majority of faults are EGR valves, injectors, or particle filter, common in modern diesel

Are judicial systems are very different. In Europe cases have to fight country by country, the European Union has no competence to start a macrocausa against Volkswagen. Not only is tries to compensate for moral damages for fraud, false advertising… but to compensate for repair costs induced by these updates, supported at the technical level from the federal authority for transport of Germany (KBA).

In view of these data, from we joined the council of NO to update the motors and retain all communications with the manufacturer, maintenance bills, etc., and they have already done so, should be placed in the hands of the platform, a Grouping of Affected by Volkswagen, which brings together 12 law firms, to be informed of their rights and possible actions against the manufacturer in court.
