Watch All These People Eat Shit While Trying To Cross A Railway On A Bike. When I was living in Detroit, there was an intense debate over where to place the tracks of a new streetcar on Woodward Avenue in the citys downtown. Running them along the curb of the road presents more of a risk to bicyclists, one line of thinking went. Its not fun traveling over rail, and a new studyand videoshows exactly why. A motorcyclist kicked the side of what looks like a Nissan Sentra on a major highway in southernRead more Read. The finding, published in the Journal of Transport Health, was the product of an experiment of sorts conducted by Chris Cherry, a civil engineering associate professor at the University of Tennessee whose study was highlighted by City. Lab. It began a few years ago, City. Lab explains, after he fell off his bike while traveling over a railroad crossing in Knoxville to get to a football game. Heres more Shortly after, Cherry was contacted by his department head, who happened to see a bad accident from his office window at the same crossing. In this case, the rider was carted away by EMTs. The department head asked him why he wasnt doing anything about it. I said, Well, nobodys done any research on it, and I dont have funding at the moment for that, Cherry says. But he shamed me into it.

The result is a compilation of more than 5. City. Lab gives an extensive, fascinating rundown of the studys details, and its worth your while to give it a read, but our headline said youd find footage of people eating shit, so well leave you with that, an excruciating four minute clip of wobbly bikes and riders collapsing to the ground. Mercedes Sprinter Turbo Limp Home Diagnosis and Fault Finding Mercedes Sprinter Turbo Limp Home LHM Diagnostics. You will probably read a great deal on the internet regarding the issues surrounding your Sprinter lapsing into limp home mode without showing any EML Engine Management Warning Lamp. I have also read these web entries with interest and have concluded that there is a lot of confusion around what exactly is going on so I have decided to add my own input so that hopefully you can sort out this irritating and troublesome issue. The early Sprinters with vac controlled turbo actuators are quite basic in operation and there are only a few elements to the control loop. These can all be checked out systematically and the faulty element identified and replacedrepaired. Let me try and explain in basic terms how the turbo control system works so that you may get a better understanding of what is going on VNT Turbo and Vacuum Actuator sometimes known as a VGT TurboSprinter Vacuum Boost Actuator. The turbo itself is a Garrett VNT variable vane turbo, the details of which you will find elsewhere on this site. WP3. 5diesel mercedes sprinter turbo rebuild  It is controlled by a vacuum actuator that moves a set of mechanical vanes within the turbo to vary the turbo charge rate there is no conventional dump valve on these turbos and many times you will wrongly read people refer to it as the dump valve actuator. The charge actuator resides bolted to the turbo body on an extended bracket, its push rod connects to a small lever that enters into the turbo body casting, moving a small lever shaped rather like a dog bone. This lever engages in an annular ring that in turn interlaces with a set of similar levers attached to each variable vane. A single action of pushing or pulling the actuator rod moves all the vanes inside the turbo in unison, developing more or less turbo charge dependant on its position. Inspect the external lever that the actuator push rod attaches to, ensure this moves smoothly as you accelerate rev the engine. Look for any misalignment of the lever throughout its stroke as it passes through the turbo body, as the bearing surfaces on this shaft can wear or oval allowing the internal lever to ride over the annular ring inside resultantly not moving any of the vanes. 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. As you rev the engine you should hear a very loud and strong tornado type howl from the air box, if you do not, and the actuator has moved pulling the lever downward there is a chance that the turbo itself is faulty. Normal operation is as follows. Stationary engine, rod fully extended, vanes in no charge position. Start engine, rod pulls lever downward slowly, vanes full charge position. Rev engine, rod moves in and out during the rev cycle, vanes apply variable charge through rev cycle Audible howl from air box. Turbo Actuator Electric Vacuum Control Valve.

Thanks a lot for your help. Its really smooth to drive now. Sprinter Boost Actuator Valve. If the vacuum actuator is not pulling down once the engine is started check for vac at the pipe, if vac is present, the actuator could be seized or faulty internal diaphragm split rectify this. If you follow the vac pipe back from the turbo you will see that it goes to an actuator that is bracket mounted on the inner wing below the air box at the back of the off side headlamp UK Vehicles  This can be pulled upward off its bracket mounting rubber and moved to a better place for visual inspection. This electrical valve actuator is popularly at fault with the Mercedes Sprinter model and your dealer will have sold hundreds of this item over time. It has a single two wire electrical plug connected to it and three rubber pipes in some cases its pipe locations are even marked IN OUT VENT. Check vac supply to this device observing and rectifying any split or leaking pipework. Once good vacuum supply has been determined, with the ignition off no power to the valve and no vacuum present the route of vacuum should be blocked by the valve to the turbo actuator. The turbo actuator supply pipe should be vented to atmosphere via the electric control valve to a small filter looks like in line fuel filter mounted above the engine and sitting by the side of the brake servo. Turning on the ignition places a constant 1. This voltage pulses during normal engine operation  vac should now be routed from actuator valve inlet to the turbo actuator outlet and the vent should now be blocked. Vacuum switching can be verified by using  a hand vac pump Mytivac or similar Simply sucking on the pipes will not prove anything, as there is an internally sprung pressure control diaphragm inside the electronic valve so that operation will not occur until sufficient vac is present   the only thing you will achieve by sucking with your mouth  is a red face An old Mercedes engineer once shared that there are two versions of the electric vacuum valve available, one with a blue cap and the other with a black cap, only the matching type should be used as a replacement. I cannot verify this information as I have only ever seen the black cap type, but best practice would suggest replacing the unit only with the correct version to be 1.

The ECU control loop circuit is quite simple for turbo actuation. The electric vac valve is controlled by simply switching the 1. ECU, this is called PWM or Pulse Width Modulation its easy to test this control voltage is present with a volt meter at the valve electrical plugconnector with ignition on. If no control voltage is present look for a break in the wiring from the valve to the ECU. Trace back the wires to the ECU connector and prove continuity exists from the ECU connector to the valve. Pin outs and wire colours are given in the included diagrams. There has been commonly reported breaks in the valve supply wiring as it is routed in front of the intercooler behind the grille and also in the area of the near side headlamp where the loom kinks back into the engine bay around the radiator. The wire colours to look for here are white and blue on my model but please check the included diagramchart for correct model notation.

It is quite common for the bulkhead grommet to displace where the main ECU loom is routed to the engine bay allowing water to enter and run down onto the ECU connectors.
