NHTSA recall 99V131001
Service Brakes, Hydraulic · Volkswagen Group of America, Inc.
Details
What's wrong: A control valve in the vacuum hose connecting the brake booster to the intake manifold may not open or close fully at temperatures below -4 f under certain driving conditions.
Why it matters: This condition could cause insufficient vacuum to be provided to the brake booster.
The fix: Dealers will install a vacuum by-pass system into vehicles operated in these states which is designed to provide sufficient vacuum for full brake assist under all weather conditions.
