Now that’s out of the way - rant over - how do we best deal with this problem and get that vehicle back on the road. My family and I have traveled all over the country with ease due to the "stealth camping" ability of this van. The Mercedes-Benz Sprinter 4×4 is priced from $67,990 (excluding dealer delivery and statutory charges) and is now available from all authorised Mercedes-Benz van dealerships. When in all-wheel drive mode, the Sprinter 4×4 utilises electronic control to direct torque to the wheels with the greatest amount of grip, and to reduce wheel slip to those with less traction. The Sprinter’s 4ETS traction system permanently monitors the speeds of all driven wheels and searches for any signs of slip, or traction loss. The 4ETS system works in close cooperation with the Sprinter 4×4’s standard-fitment ADAPTIVE ESP (Electronic Stability Control) system, which constantly monitors the vehicle’s driving status, always on standby to help correct a loss-of-control condition prior to its occurrence. The main control system that provides the Sprinter 4×4 with superb all-wheel drive traction is called 4ETS, or 4-wheel Electronic Traction System.
All models in the Sprinter 4×4 come equipped with the same suite of safety and comfort features that have made the Mercedes-Benz Sprinter not only an award-winner, but also popular with customers from a variety of industries. The safety of seat belts was enhanced greatly by the innovation of the tensioned seat belts. An interesting innovation here is the M mode which allows some thrill since the driver can shift gears like in a manual for a pre-defined time after which the system reverts to the default automatic mode. In the interplay between innovation and tradition we have created a stylish, sporty and elegant luxury sports car with the classic, well-balanced hallmark SL proportions: the long bonnet is followed by a compact, set-back passenger compartment. First, it can be ordered as a passenger van or a cargo van. Size-wise, customers can select from two body types (enclosed van or cab-chassis), two roof heights (standard- and high-roof), and two wheel-bases (mid- and long-wheelbase) which in turn give the choice of two different body lengths.
Remove the two pins that are also fastened to engine brackets at the rear and front of the head by the fuel filter. I am afraid that a single 6mm cap head pin used on one edge of a single steel injector clamp, tapped into an aluminium head is just engineering madness from a commercial maintenance point of view. Once the injector is out, clean it off and place it safely out of the way then recover the single copper washer from the hole in the head that forms a gas tight seal for the injector against the aluminium cylinder head. Having rectified many ‘chuffing’ injectors and dealt with the famed ‘black-death’ on many sprinter engines and its close derivatives used across the complete range of Mercedes Diesel vehicles, I can honestly say that the hold down mechanism used to secure the injector in the head is definitely the engines number one Achilles heel.
If it’s seized then at this point re-assemble the engine and take it to a diesel specialist as damage to the injector or head can be very expensive indeed and botched repairs will easily exceed the cost of it being done by a professional in the first place - you have been advised. If the ‘chuffing’ has been noticed early on, none or very few ‘black death’ carbon deposits will be seen, just wetness from ejected diesel resulting from the failing combustion process forced up around the leaking injector out to atmosphere on the cylinder head. If the injector rotates, begin to pull it upwards whilst twisting the body, if it jams, twist it the other way and work it using some penetrant or WD40 in the area around where it enters the head. Remove completely the steel fuel supply pipe from between the leaking injector and the fuel rail along with its injector electrical connector; tie this cable out of the way of the work area.
If the leaking injector is not obvious, then clean down the area with Gunk or other degreaser and dry off the area (engine off of course) completely. Pop this tool down the hole and clean the seat as if you were grinding in a valve. You simply need to wipe and clean frequently. All models from the Sprinter 4×4 range feature selectable all-wheel drive, allowing the driver to engage drive to all four wheels at the touch of a button, without the need for any manual activation. When a slipping wheel is detected, 4ETS selectively applies braking force to limit its rate of slip and simultaneously sends drive torque to the wheels with greater grip. Surfaces such as snow, ice, and mud often limit the operational capacity of vehicles, and the clever all-wheel drive system fitted to the Sprinter 4×4 delivers substantially improved handling and traction in such poor road conditions, thereby extending the already-impressive capabilities of the award-winning Sprinter. The new Sprinter 4×4 range utilises extensive all-wheel drive know-how developed by Mercedes-Benz, which boasts more than a century of experience with four-wheel drive technology. Try to rotate the unclamped injector, if it moves freely by hand then great, if it won’t budge try a little more force - but not too much.
