BMW 335i Oil Cooler Line Replacement

I'm replacing the oil-cooler lines on a BMW 335i N54. If you're tracing an oil leak around the cooler plumbing, this video shows the line-replacement project and gives you a chance to compare the connections on the actual car.

What you’ll see in this one

A wet oil-cooler hose doesn't automatically tell you which seal or fitting failed. Confirm the leak source and the line design on your car before ordering parts.

A closer look at this job

This video covers replacement of BMW 335i N54 engine-oil-cooler lines. The lines, fittings and routing are useful search topics because oil in this area can come from more than one nearby connection. The repair shown is specific to the cooler-equipped car in the video; do not assume the same plumbing is fitted to every 335i. Watch for an overview of the access and replacement, then compare line ends, sealing arrangements and factory fitment information to your own vehicle.
