What to do if your sprinter has a leak?
If a visual inspection doesn’t reveal a clear leak but you still suspect one may be the problem, investing in an Intercooler Pressure Tester may be a good idea. These devices allow you to pressurize the intake and intercooler system and find any leaks you may have.
What causes boost to fail on Sprinter van?
Turbocharger Actuator On the modern diesel engine used in the Sprinter van, boost pressure is controller using a vane-system. The control valve for the vane system is electronically controlled and can fail. The turbocharger is still healthy, only the control valve has failed.
What should I do about my pre 2007 sprinter?
Pre 2007 turbochargers can have their actuators adjusted. Turbo Resonator: Common failure part on these vehicles. Can replace with a durable aluminum unit to fix the faulty factory part.
What causes a sprinter to go into limp home mode?
This is common condition with a few common causes. If you have an Sprinter with the 4-cylinder engine (OM651) see this article about a common issue on this engine that causes Limp Home Mode. Low power – enough power to get to 50 mph in some cases, but not to keep that speed up a hill.

What causes the engine hose to split on a sprinter?
Replace the intercooler o-ring seals or refresh the hoses themselves to fix any leak you find. The most common leak on the V6 engine is the green o-ring in the metal pipe that is attached to the turbocharger. Any curved hose is also a candidate for developing a split. Check all sides of all curved hoses by squeezing the hose vigorously.
How can I tell if my Mercedes Sprinter has a problem?
A quick and dirty test to indicate any problems with the variable vanes is to remove the air box or air filter housing and listen as the engine is revved. Once the engine is started, the vac actuator rod should move down slowly as vac builds, this in turn should apply force to the lever moving the vanes into a fully charged position.
Why is the fuel pressure not maintained on my sprinter?
Causes for this pressure not to be maintained could be due to internally leaking injectors, faulty fuel pressure regulator or its O-ring seal (see covering article here ), faulty rail pressure sensor, High or Low pressure fuel delivery pumps.
Why does my sprinter truck not start up?
Internally there really are not many parts and as long as it stays lubricated with fuel it probably will not fail. The glow plug issue will not cause your idling problem. On this truck when you have a glow plug fail it will most likely take the glow time relay (located under the battery box) with it.
What is part number for sprinter fuel regulator?
Dont let your dealer try to sell you the whole regulator for $300 the o-ring only kit is part number is 05175439AA. 4. If this is not the problem you may have too much fuel bypassing inside worn injectors. You need to run a fuel quantity test.
How does the high pressure pump in a sprinter work?
The high pressure pump builds the high pressure and delivers it to the fuel rail manifold, which buffers out pressure fluctuations and distributes fuel to the individual injectors. The fuel quantity valve (fuel control actuator, M-Prop) in the high pressure pump controls pressure output from the pump.
