Lemon Law is the car has to be in the shop for the SAME repair 3 times and still not fixed. That's unfortunate that happened but Audi will take care of you.

What are a Reasonable
Number of Repair
Attempts?
A “reasonable number of attempts” for most
eligible vehicles has occurred when:
1. Diagnosis or repair of the same “serious safety
defect” has been attempted two* or more times
(with at least one during the “eligibility period”)
and the defect continues to exist;
OR
2. Diagnosis or repair of the same
“nonconformity” has been attempted four*
or more times (with at least one during the
“eligibility period”) and the defect continues to
exist;
OR
3. A vehicle has been out-of-service for diagnosis
or repair of one or more nonconformities or
serious safety defects (whether or not repaired)
for a cumulative total of 30* calendar days, with
at least one ‘attempt’ for each defect and 15*
of those days occurring during the “eligibility
period
