FAQQuestions about the Coupe Quattro manual
Which Coupe Quattro years does this manual cover?

Is this the OEM Audi Coupe Quattro manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Audi published for the Coupe Quattro, organized by system — not a condensed aftermarket summary.

Why do some Coupe Quattro years cost more?
Every Coupe Quattro year is $40.99.
Is this a subscription?
No. One payment, and the manual is yours to keep — unlike per-vehicle subscriptions that renew every year.
How do I get the manual after purchase?
