Why should buy MB Star Diagnostic Tools Xentry connect?

After 2015, all Star Diagnosis equipment is no longer supported. That means there is no update diagnostic data for the newest cars and their systems. The lack of the possibility of coding and programming of electronic units due to the backlog of the software data level in the device, from data in the electronic control units of the car.

At the end of 2014, among dealerships, almost all of them who previously used Star Diagnosis Compact4 with SDConnect DoIP multiplexers were almost gone. Instead, dealerships choosed Xentry Kit kits which include the latest Xentry Connect multiplexers and Xentry Tab tablets from Panasonic. Tablets are custom-made, also they have a “civilian” version – the Panasonic Toughbook CF-D1, which has a more powerful configuration but shorter battery life than the original Xentry Tab.

Honestly, it seems exaggerated for non-dealer use Xentry Tab. While for dealers, that is necessary.

And what about workshop service?

Undoubtedly, the tablet from Panasonic is well while the price is too high. The cost of the Japanese tablet is realistic to buy pieces of eight new laptops or tablets from other manufacturers.

So , we suggest to buy Xentry connect from us , then buy a laptop yourself . the software from which Xentry Connect is managed can be installed without any problems on any computer that has a 32-bit version of Windows 7, Windows 8 or Windows 10. It’s clear with Xentry Connect itself – there’s no alternative .

After all, in this choice there are many reasons that encourage one to make a decision. The main thing is one: since 2015, the diagnostic multiplexer Xentry Connect C5 becomes the only one used at dealerships.

Thus, by purchasing this equipment, you do not lag behind the progress. You use in your work the best that is available today. Each your client, seeing with his own eyes that you in your work use the same device that he saw at the dealer’s service station, will understand that he made the right decision entrusting his car to your specialists.

Real MB star C5 price:

As for the price, real MB Star C5 will be sale 1095 EURO in eobdtool.co.uk without shipping cost. The price is about 2 times higher than the old C5.

Which better VVDI2 BMW vs CGDI Prog BMW For BMW key programming

Both Xhorse VVDI2 and CGDI Prog are able to work well in BMW immobilizer. So, what’s the difference of both tools in terms of BMW key programming? which better?

First, The biggest difference!!!!!!!!!


EWS Yes No
CAS Yes Yes
FEM Yes Yes
EDC Yes Yes

Note 1: VVDI2 can work for old cars with EWS immo, incl. EWS1/EWS2/EWS3/EWS4

CGDI Prog cannot work for cars with EWS immobilizer systems.

Note 2: Both VVDI2 and CGDI Prog supports CAS1/CAS2/CAS3/CAS3+/CAS4/CAS4+

Note 3: Model with EWS: E31/E34/E36/E38/E39/E46/E52/E53:

EWS, E36 9/93-12/93 = links the door lock switch to the DME and OBC. If the door was locked with the key (or factory alarm) the car will not start without the doors unlocked with the factory key or entering the code into the OBC. In other words, you can’t smash the window and hot wire the car because the DME has killed the ignition and fuel systems.

EWS-I, E36 1/94-12/94 = same as above but added a starter immobilization relay and transmission position switch.
In either of the above systems the DME is passive. It only receives signals from sensors and modules. So the DME is not as tied into the body electronics as much as EWS-II.

EWS-II, E36 1/95-8/96 = similar to the above but with an electronic key, EWS module (“brain”), and the DME all linked together. The same door lock logic remains. All systems for starting the engine are run through the EWS module (starter relay, starter power, fuel, ignition). The key sends a signal to the EWS module and the module asks for a matching signal from the DME. If the two signals don’t match the EWS module will not start the car. The EWS module also checks for OBC function and transmission park/neutral position.

EWS-III, E36 9/96-8/99 = revised EWS-II system with added clutch position sensor and revised module and wiring.

Second, VVDI2 and CGDI differs in authorization & price

Xhorse VVDI2 BMW : 1049USD

The kit comes without OBD function and basic function (Transponder Auto Key Programmer  and Passthru J2534).

BMW FEM/BDC and CAS4+ Function is not available.

Unlimited use once the function is authorized.

CGDI Prog BMW : 698USD

The programmer comes with OBD, FEM/BDC and CAS4+ function; price included

In the long run, Xhorse vvdi2 will help save a lot, esp for those working for a workshop or auto repair garage.

But if you’re a DIYer, CGDI BMW is cost-effetive.
