This turbo oil return pipe with OE number A2515003575 is fully interchangeable for Mercedes-Benz 2006–2013 R-Class, 2006–2011 M-Class and 2007–2012 GL-Class, covering all M272 petrol V6 and OM642 diesel V6 turbo variants. It undertakes the key task of recycling lubricating oil inside turbochargers to the engine oil sump.
Adopting reinforced high-temperature silicone rubber and anti-rust metal joint structure, this pipe effectively resists thermal aging and mechanical shaking from turbo operation. All bending radian, thread size and mounting clip positions strictly follow OEM specifications, realizing seamless docking with turbo housing and engine oil pan.
The product undergoes thousands of cycles of high-temperature oil immersion and vibration durability testing, suitable for city daily driving, long-distance family trips and heavy-load off-road use. It completely solves common faults of original aging oil return pipes such as oil leakage, turbo abnormal rattling and low lubrication pressure warning, providing affordable long-term turbo protection for early Mercedes large luxury vehicles.
