Mercedes AdBlue System began with 2009 model years.

The Kleemann KD-Box is an efficient performance product for all Mercedes-Benz CDI models and also for most of the new BlueTec and BlueEfficiency engines.

The KD-Box is a highly convenient tuning solution as it is fitted only by cables and plugs with no need to open the engine control unit (ECU) or to replace any components. The KD-Box is adjustable and can adapt to the characteristics of the individual engine, ensuring a perfect power curve and at the same time preventing overload. In addition to the increased levels of power and torque (up to 25%) the KD-Box provides a sharper throttle response for maximum driving pleasure, and has been shown to improve fuel economy in many cases.

BlueTEC is a trademark name used by Mercedes-Benz to describe its diesel engine exhaust treatment system. In order to keep up with the steadily evolving and increasingly demanding emissions laws of North America and Europe, the company has designed and released two versions of this system. Version one was released for the U.S. market in the form of the 2007 E320 BlueTEC sedan and was designed to utilize, the then newly introduced, Ultra Low Sulfur Diesel (ULSD). As a next step, Mercedes-Benz has released the more sophisticated R, ML and GL 320 series BlueTECs with AdBlue injection diesels that meet America's demanding BIN 5 emissions standards and are on-track to qualify for Europe's EU6 parameters.

Any user results out there?

i installed one on my 2007 CDI ML and once the right setting was found
(adjustable) it works fine, marginal MPG increase but better torque on acceleration.
No issues but this unit will ping if the right setting is not dialed in.
I have a friend with the same model ML and this has been my comparison. Good Luck, RK

What do you mean when you say "ping"? Is that a sound you are hearing from the motor? Diesels are compression ignition so the low octane "knocking" like a gasser is not possible.
Thinking of getting one of these KD boxes, and would like to know more user info if any one cares to elaborate.

the KD box works on fuel pressure and is adjustable for various types of diesel motors. the (ping) happens if the setting is not right for your particular motor. sounds like a mild knocking but is just a matter of finding the right number. i started at 5 and ended at 6. that's it. RK
