I agree... but you have to play the percentages. VW just arnt up to the job.
The EA888 engine range is used in a wide range of veihcles including rep models yet there does not seem an outcry about it about anywere else.
First thing i always ask when i hear stories of cars engine problems is what has been done to it.
Mainly because of my own past experiences with modified cars. I killed a 1.8T but it was not VWs fault it was mine for believing the hype about a company and so i changing the mapping and this caused overfueling that killed it.
Companys don't build in margins in designs like they use to as they have much tigher tolerances and tighter budgets to work with. Things are not engineered like they were. As a designer im constantly battling the bean counter and want to over engineer but have to wind it back because of costs and rivals competition.
