after Volkswagen spent some two years suppressing the work discovered in 2012.
They have form here. There are at least two cases of nailed-on candidates for recall that VW spent years resisting claims from affected owners and baffling the regulators with bullshit over, rather than just take it on the chin.
They're also one of the worst manufacturers for getting "goodwill" out of (a contribution to the costs associated with a major component failure when the vehicle is just out of warranty).
I'm amazed anyone touches the ruddy things with a bargepole.
They must have the world's best PR department, as the actual quality of their products and their attitude to customer service is pretty much the exact opposite of public perception. Presumably their legal department is always busy keeping a lid on anyone or thing trying to tell the truth. If everything in life really were as reliable as a Volkswagen, the human race would have died out eons ago.
 Look up VW ABS/ESP unit failures (mainly Golf models, but most affected) and Passat injector failures here.
 Exploding 1.4TSI engines for a start. Those make the legendarily iffy Rover "K" series look like a paragon of reliability.
