Volkswagen Tiguan significant oil leak issue at 50,000 miles on Volkswagen Tiguan

Some Volkswagen Tiguan owners report experiencing significant oil leak issues around the 50,000-mile mark, often due to oil separator failure, which can lead to increased pressure and potential cracking of the oil pan and upper timing cover. Additionally, common causes of oil leaks include worn-out drain plugs, damaged gaskets, and oil system component failures. Repair costs for addressing these oil leak issues can be substantial, potentially reaching just under $2,000 for parts and labor. Owners are advised to promptly identify the source of the leak and seek inspection from a qualified mechanic to prevent further engine damage.
