I received email notification from Bosch with this information as well, which states:
"If you already filed, or if you file in the future, an approved claim in the 2.0-liter Settlement, you will automatically receive a payment through the Bosch Settlement."
Email also states:
"Your payment could be up to $350 in addition to what you may be eligible to receive from the 2.0-liter Settlement with Volkswagen/Audi (“2.0-liter Settlement”)."
I assume Bosch will use a mileage-based scale to determine the amount of compensation. Since I've already turned in my 2 CRTDIs, I'll simply wait until further notification from Bosch.
