If your Volkswagen Passat illuminates the low brake fluid warning light, have your car checked as soon as possible. The main cause for this problem is that the end flares for the brake lines weren't properly manufactured and won't create a proper seal. The brake lines slowly leak over time at the brake fluid reservoir or the brake caliper. These brake lines were manufactured by Sanoh America Inc located in the United States1. There is a recall covering certain VW Passats. If your VW is part of the 47N3 recall2, your dealer should fix this problem free of charge. Approximately 1000 Passats were affected by this recall.Back to top
