Start the car and move it to a location that’s dry and clean so you can see if there is any leaking. Let the VW Passat run for approximately five minutes and then inspect the surface below. If you see liquid, you have a leak.
Inspect the hoses and clamps again to see if you can determine where the leak is coming from. Use your hands to run down the hose to feel for the source of moisture. Replace that hose and clamp.
Tips & Warnings
Check your hoses and clamps for wear and tear when your car’s engine is cool. Whenever you replace any hose in your VW Passat, always replace the clamps that secure it at the same time. Inspect the fuel hose in the 1993 VW Passat. It was recalled due to a tendancy to shrink beyond its clamp, which creates a fuel leak. Contact your dealer for more information.
