Hello All,
I am interested in both the 2011 Jetta Wagon and the Audi A3. In reviewing the specs and taking with both dealers (mistake
), I cannot find a good answer as to why Audi uses Blue urea treatment and VW does not in their basically identical engines???
It seems the exhaust systems and various filters/cats are the same... Why does Audi add the urea??
Also, why is VW engine oil capacity one more qt than Audi?
I have reviewed the excellent FAQs of this forum, but could not find an answer.
Thanks,
BudK
