FAQQuestions about the 90 manual

Which 90 years does this manual cover?

Every year from 1988 to 1995 — 7 separate manuals, one per model year. Pick your year in the selector; the manual you receive is matched to that exact year, engine and trim.

Is this the OEM Audi 90 manual or an aftermarket guide?

The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Audi published for the 90, organized by system — not a condensed aftermarket summary.

Does it include 90 wiring diagrams?

Yes. Full wiring diagrams are part of every 90 manual, alongside repair procedures, specifications and diagnostic information.

Does the manual cover 90 recalls?

15 recalls are on federal record across the 1988–1995 90, listed by year below. The manual carries the manufacturer's diagnostic and repair procedures behind the systems involved; the recall repairs themselves are performed free by Audi dealers.

Why do some 90 years cost more?

Every 90 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.
