1991 Audi 100 common problems

The most-reported problem areas across all 10 owner complaints filed with NHTSA — and what to check before you buy.

Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
Power Train
Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
Service Brakes
Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
Hydraulic
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Air Bags
Confirm the airbag light turns on then off at startup — if it stays lit there's a fault (costly, and a safety risk). Check for signs of prior deployment.
Fuel System
Sniff for fuel odor, check for leaks, hard starts or stalling, and confirm the fuel gauge reads correctly.
