W164 fails to communicate after SCN coding nightmare!!!

**cowfunone** · 14th July, 2012, 07:56 AM

Need help!
My pre-facelift W164 is retrofitted with the NTG 2.5. Coding was performed with a developer mode DAS.
Recently I brought the car into the dealership for a firmware upgrade in order to upgrade my map.
They did that, but they also tried to SCN code my NTG 2.5 to no avail.
The end result is that my car is no longer communicating with DAS! None of the control unit is communicating at all!
Please see fault code.
Apparently, they are still able to read and check fault codes with their machine, but I no longer am able to!
What can I do, and what should I ask my dealership to do?

you try with Xentry ??

Xentry does not communicate with my car, it loads DAS.

i.e. unless the newer version of Xentry abandons DAS and does diagnosis on my car directly.

I use 2010 09 version of Xentry/DAS. The thing is, if it was working before, why would it not work now?

Maybe the new software in command don't work with DAs and work with Xentry. Remeber the software version now in car is new and your Das is Old.

What smayer say it's true!!!
Update your Star Diagnosis System and eyerthing will be ok.
Your Ecu Version is newer than your Star System.

Thanks for the insight
Are there any recent instructional on installing a newer xentry?
should I do 05 2012?

I also need to find the software I guess
Haven't done this for close to 2 yrs now
Any direction would be appreciated
Thanks

Just a quick reply that what shacky and smayer suggested did not work. I installed 01 2012 days and the same problem persisted. Only voltage is readable, not the car.
