Original BMW Turbocharger Oil Line for BMW 335d (2009–2011) and X5 xDrive35d (2009–2013)

Feeding oil to the turbocharger on the M57N2 diesel, Original BMW oil pipe 11-42-7-795-971 fits the BMW 335d and the X5 xDrive35d. A turbocharger's shaft spins very fast on a thin film of engine oil, and the oil also carries heat away from the bearing housing. A supply line in good condition is therefore essential to turbo life. This line is one of three connections to the turbocharger oil line distributor. It weighs 75 g, is made in the United Kingdom, and is sold as a single piece. BMW's parts data shows production beginning in August 2006.

Original BMW Parts carry a 24-month parts warranty.

BMW applies this pipe to the M57N2 engine in the E90 335d sedan and in the E70 X5, both before and after the X5's facelift. A leaking line puts the turbo at risk of severe and expensive damage. Visible oil around the turbo or in the engine bay, a turbo that runs hot, and whining, whistling, or grinding from the turbo area can all point to an oil line problem. Blue smoke is another warning sign. If you see any of these, inspect the oil lines right away.
