What do you think the problem is with the VW approval that’s causing all this? 504 00 must be deficient in some way.I did road service for 7 years and I'd be willing to bet 99% of the broken down cars on the road equate to 1 of 3 things... out of gas, a flat tire or the battery is dead... after that comes various mechanical and electrical maladies, but they are extremely rare compared to the first 3.. even crappy oil takes a long time to show up, and the type of person who doesn't do maintenance is the same type who even if they paid top dollar for oil would still have the same problems.
