Yep, 60,000 miles the steel coated lines under the driver's side floor panels (under body) rusted at the plastic clamp points just behind the front wheels. All of these lines will go. It is just a matter of salt and time. Ocean spray or man made spray on the roads. This X5 NEVER goes out in the rain or salt. Every line I see on these E53 has pits as the spray on coating used at the factory is compromised. see examples at: https://xoutpost.com/bmw-sav-forums/...ine-check.html
