A2515003575 OEM Turbo Oil Return Pipe for Mercedes W251 R-Class, W164 ML & X164 GL
OEM turbocharger oil return hose marked part number A2515003575 matches Mercedes-Benz W251 R-Class (2006–2013), W164 M-Class (2006–2011) and X164 GL-Class (2007–2012), compatible with M272 V6 gasoline and OM642 V6 diesel turbocharged powerplants. This low-pressure oil return pipeline guides lubricant drained from turbocharger bearing housings back to the engine oil pan to sustain steady turbo bearing lubrication circulation.
Three-layer high-temperature silicone reinforced rubber construction resists constant 110–140℃ oil heat and turbo assembly vibration fatigue, while corrosion-resistant metal threaded connectors prevent thread stripping during disassembly. Pre-shaped pipe bends accommodate the cramped under-engine layout of old Mercedes V6 turbo models, no manual bending or cutting required during replacement.
Aging original turbo return pipes will crack and leak engine oil under long-term heat erosion, causing insufficient turbo bearing lubrication, abnormal turbo noise, oil puddles under the vehicle and accelerated turbocharger wear. Installing this factory-equivalent oil return hose restores complete turbo oil circulation, protects turbo core bearings from dry friction damage, avoids costly turbo assembly replacement, and stabilizes engine power output for Mercedes vintage V6 luxury MPVs and SUVs.
