The new Mercedes Benz diagnostic tool MB SD Connect C5 is verified working great. Here are customer feedback to Benz C5.
SD Connect (not original Xentry Connect C5).

1.“Mercedes Sprinter year 2006 and 2014 works, both thediagnosis. All the personal cars also works, no problem”

2.“All the trucks including euro6 also works, no problem. Bus Mercedes Tourismo euro5 year 2010-2012 test works, BUT year 2014 euro6 does NOT work, it says that the license is invalid. Both sd c4 and sd c5, we have tested both on the same cars, to be sure.”

3.“SD Connect C5 this one customer has test, works good, in function it no difference with SD C4, but performance it is better. So you can buy MB SD C5 if you want buy new MUX. SD C5 use the same software as MB SD Connect C4.

4.“I have used V2016.12 software. I am ready to order the new 2017.05V software. It is said that the 2017.05 DAS/Xentry has improved a lot. New software in SSD runs faster and much more steable on Windows 7 or Windows 8 instead of Windows XP system. Also, new WIS and EPC parts catalog offers more full information for more models.
Well, my friend with 2016.12 version saying earlier Daimler AG needs the user name and password to login, but in this version, no need that.”

It started like most of them…….
As a request !!
So it was a combination, of a faulty SBC, common sence, LOTS of time and GUTS to figure this out

Make sure engine is running !!!

In Developer mode you need to go to Entwickelingsdaten –> ansteueringen –> Gesamstliste aller Ansteuerungen

to see how many times brake has been pressed there is a line that says: Bremsenzahler (DJ_GetBrLive) or DJ_GetBrLiveTime

then 1 line down there you see Bremsenzahler aktualisieren und Lebensdauerzahler F neu berechenen –> click it !
Parameter uINBR = 0
then click F3

1 line down Bremsenzahler auf beliebigen Wert setzen (DJ_SetNBr) –> click it
Parameter uINBR = 0
then click F3
then scroll down untill you see the line’s :

Lebensdauerzahler F neu berechenen (DJ_CalcLiveTime)
Parameter uINBR = 0
then click F3

Lebensdauerzahler F neu berechenen und schreiben (DJ_BuildAndWriteF)
Parameter uINBR = 0
then click F3

Log out of SBC !!
log out of verhicle !!

let engine run at least 10 minutes or drive at least 10 minutes

If no coils are damaged, SBC fault code is not AKTUEL nomore

Note:
(Dj_setNBr) Here you SET new brake counter value back to 0
(Dj_setNBr) uINBR = 0

Resetting break counter to zero is in my opinion, not messing with …..

each time SBC powers up it checks itself time after time
If there occures any problem in SBC unit with valve, brushes or whatever, it will go into error anyway. that you will NOT be able to erase in Dev mode

If you switch on contact of Brand new MB with SBC and press break 300.000 times it will go into this so called “error” you wanna say SBC is broken then ? without driving a milimeter ?

No it’s indication to have SBC unit checked by MB workshop $$

Yes it’s true that MB has to replace Faulty SBC units for free
since Factory will pay all there labor & material
But most Dealers try to have costumer pay for this procedure claiming costumers car has no a Dealer serviced History
