New protocols for a safe and effective  work on TCMs like TEMIC DQ250 and 500 MQB and Continental VGS2-FDCT, supported by VAG and Mercedes-Benz. You can work in OBD  and Service Mode, to give you more possibilities  to offer high quality services and professionalism to your customers.

TCUs involved are:

You can work on hundreds of vehicles among Audi, Seat, Skoda, Volkswagen and Mercedes-Benz. Lots of vehicles available for you to work efficiently and safe. You have two solutions: – OBD or Service Mode –  according to the needs of your customers and of your work. We are with you to make your work always easier.

KESSv2. Reprogramming fast and easy.

KESSv2 is an OBD programmer for TCU and ECU

The most versatile tool to read and write through the OBD.

Being easy to use , the highest vehicle compatibility of the field and the constant updates make KESSv2 the most versatile tool  to read and write thorugh OBD.

Virtual Reading

Virtual Reading gives you the chance to receive the correct file, with  KESSv2 is easy and fast: our tool identifies  the ECU automatically, searches for the correct file on our servers and in just a few easy steps downloads the corresponding original file.

Even more Service Mode.

Also, to repair and recalibrate the TCUS.

Full reading and writing without opening the TCM. Thanks to this modality, you can elaborate and repair the TCU without ever having to open it! The best for your work, with minimized error margin.

Elaborations

To really get the most out of a vehicle, we need to intervene with reprogramming on the ECU for lower consumption or higher performance. However, with interventions also to the TCU, the vehicle elaboration becomes complete and optimized to the maximum: part of the performance limitations is included in the TCU so, on significant elaborations, it is necessary to also modify the TCU to develop 100% processing.

 

Repairs

Thanks to the full reading and writing opportunity you can satisfy even more customers because you can repair the TCU, thus avoiding replacing one of most expensive components of the vehicles. A great advantage for the owners of the vehicle and certainly also for your business.

The Service Mode protocols we offer are the most concrete and real answer: we give you reliable solutions that make your job faster, easier, and safer.

New Service Mode cable

To work in Service Mode on TEMIC DSG DQ500 MQB the new 144300T118 cable shall be used!

TEMIC DSG DQ250

The DSG6 was the first dual-clutch automatic transmission produced by VAG in 2003. It is a revolution that led to a radical change in the driving concept, in addition to opening the way to automatic transmissions production, intended for non-premium vehicles; just think that in 18 years of production have been sold over 26 million of cars equipped with DSG!

The first car to equip this gearbox was the R32 Golf, introducing the “R” logo, that still today wears the most powerful and sporty versions of the Wolfsburg compact car.

The transmission is designed, like all “DQ” gearboxes, for transversal mounted engines and holds a maximum torque of 400Nm, besides this you can use it for both front-wheel and four-wheel drive models.

In this case, the gearbox uses two primary shafts that respectively operate the even and odd gears linked to two wet multidisc clutches. What allows the speed in shifting of this transmission is the fact that while driving the gearbox has both primary shafts with engaged gear, that’s why, to complete the transition from one gear to another, it will only be necessary to move the two clutches to disconnect the shaft with the previous gear and to engage the shaft with the next gear. Obviously, the scaling has the same principle of operation.

 

The automatic transmission is managed by an ECU that, based on the parameters set in the map, reduces, or increases the torque, depending on whether you up or downshift. Furthermore, the TCM applies the rev matching during downshifting, the “sailing” mode in the last versions and also the “Tiptronic” mode (sequential manual gearbox).

The parameters you can work to improve gearbox performances are torque and rpm limitations, oil pressure of the hydraulic actuators, times and shifting threshold.

Thanks to K-TAG Service Mode new protocols and to ECM Titanium remapping software you are autonomous and independent in every application.

TEMIC DSG DQ500

The great experience developed by Volkswagen though the years on automatic transmissions has made them the best for what comes about performance and efficiency.

Born as the DQ200 successor, after only 3 years, VAG produced DQ500, a transmission developed for transverse seven gear motors , mainly associated to AW drive  and displaced  to handle the torque up to 600Nm.

Differently from its original version, clutches are wet and not dry,  both are coupled  to primary and secondary shaft managing odd and even gears.

This transmission is usually equipped on VW Transporter, Tiguan or Audi RS3, VW Passat BiTDI or Audi Q3 in all 2.0l versions diesel or petrol.

CONTINENTAL VGS2 7G-Tronic

The 7G-DCT  is the transmission designed by  Mercedes-Benz for small hatchback such as Mercedes Class A W176, Mercedes GLA X156, Mercedes CLA C117 and Mercedes Class B C117. It’s a transmission  derived by the need to have a more performing, compact and higher quality gear shift than the old gen robotized gearbox. 

As for the DSG, we deal with a 7 gear transmission  with two primary coaxial shafts linked to the two clutches  that manage odd and even gears.

All is managed by an electronic control that works on the electrohydraulic systems  that allow the movements  of the activators for the connection and disconnection of the clutch during the  gear shift.
