BMW 750i turbo oil leak not corrected after oil replacement on BMW 750i

Some BMW 750i owners report experiencing persistent turbo oil leaks even after an oil replacement, which may indicate underlying issues. These leaks can sometimes stem from pre-existing conditions that were unnoticed prior to the oil change. If oil is detected near the turbocharger oil lines or the turbo itself, further diagnosis is needed to identify the source without removing the transmission. Additionally, some owners find that oil leaks can originate from the turbos, suggesting potential problems that may require attention or replacement. Worn gaskets and seals are also common causes of oil leaks in BMWs, necessitating inspection and possible replacement to prevent further issues. To address these concerns, it is recommended that owners conduct a thorough inspection of the turbocharger components, assess the condition of the turbos, and check gaskets and seals for wear to effectively resolve the oil leak problem.
