It&#x27;s a different solution, but I don&#x27;t know if it would be better. How do you think it&#x27;s better?<p>VW doesn&#x27;t want their cars going into limp mode. They don&#x27;t want customers calling up asking why their car is acting funny. They don&#x27;t want to increase the maintenance load on their customers. They don&#x27;t want customers coming in for unnecessary service appointments (especially for stuff they wouldn&#x27;t be able to charge for). Making a tank big enough to last as long as the motor oil seems like an easy, low tech solution. Sometimes simple is better.
