BlueTec Sprinter Turbo Vacuum Cell – 6540905300OE

SKU: 6540905300OE - qty 1

Ensure your Sprinter’s turbocharged diesel engine runs smoothly and reliably with this OEM-spec turbo vacuum cell — an essential part of the boost‑control system for variable‑geometry turbos (VNT). The 6540905300OE vacuum cell helps regulate vacuum supply to the turbo actuator, enabling correct vane movement for proper boost and engine performance.

✅ What This Part Does & Why It Matters

• Controls VNT turbo vane actuation: The vacuum cell provides the vacuum needed to operate the actuator on VNT turbos. This actuator moves internal vanes inside the turbo to change boost flow dynamically. Proper vane movement ensures the turbo delivers correct boost pressure across RPM. 

• Ensures stable boost pressure and engine performance: If the vacuum cell or associated vacuum supply fails or leaks, the vanes may lock or operate incorrectly — leading to under‑boost, loss of power, poor throttle response, high exhaust back pressure, or the engine entering “limp mode.” 

• OEM‑spec replacement for Sprinter‑compatible VNT turbos: 6540905300OE corresponds to the factory vacuum‑reservoir / vacuum‑cell spec used on certain Mercedes‑Benz diesel turbo applications. Using OEM parts helps maintain proper turbo behavior and avoid mismatched or substandard aftermarket substitutes. 

• Critical when diagnosing turbo problems or performing turbo/engine work: If you’re replacing or servicing a turbo, vacuum pump, vacuum hoses, or actuators — having a fresh, reliable vacuum cell helps ensure the whole boost‑control chain works correctly.

• Essential for longevity and reliability: Diesel VNT turbos depend heavily on vacuum‑based vane control; a leaking or weak vacuum cell can compromise turbo life, fuel efficiency, and engine health over time.

🔧 Fitment & Usage Advice

• Verify engine & turbo configuration: Not all Sprinter diesel engines or turbos use a vacuum‑cell‑controlled VNT system — before ordering 6540905300OE, ensure your Sprinter’s turbo system matches (check engine code, turbo type, vacuum plumbing).

• Inspect vacuum supply lines and valves when replacing: Often, issues blamed on turbo or vacuum cell failures come from cracked vacuum hoses, bad valves, or leaks elsewhere in the vacuum supply chain. A full vacuum‑system check is recommended. 

• Recommended when: experiencing boost/under‑boost codes, turbo‑related limp mode, loss of power, erratic boost behavior — or when doing maintenance/repair on turbo, vacuum pump, or intake vacuum system.

✅ Summary — Why You Want This Part

If you own a VNT‑turbo‑equipped Sprinter diesel van, the 6540905300OE Turbo Vacuum Cell is a vital, often overlooked component that ensures:

• Correct turbo vane control and boost regulation

• Consistent engine performance and throttle response

• Avoidance of boost‑related faults or limp‑mode events

• Proper operation after turbo or vacuum-system repairs

Installing a fresh OEM vacuum cell — especially on a high‑mileage or previously vacuum‑system‑modified Sprinter — gives you peace of mind that the turbo’s boost control remains intact and reliable.
