|VW Passat Volkswagen Golf TDI Diesel Piezo Injector Replacement Recall: Photo credit : 1810martin|
I have been very impressed with the way Volkswagen handle warranty and safety related issues on their cars. Some time ago when I owned a VW Golf Mark 2 it was recalled for replacement of the heater matrix. Quite incredible when the car was 13 years old at the time and the original matrix had clearly worked ok for all that time.
