diagspeed fbs4

cgdi mb fbs4

vvdi mb fbs4

Fsb4 & fsb3 key


cgdi mb fbs4:

Confirmed! CGDI MB can read & write FBS4 keys

Images means a lot:

***CGDI MB allow users to program a new key through OBD. All done with a tool. That’s the reason why people look for it.


vvdi mb fbs4:

No. it’s not possible to read data and password for the newest Mercedes cars after 2015 with FBS4 EIS.

vvdi mb is ideal for BGA keys and the other.


To be informed: VVDI MB often works with VVDI PROG, since there are some eis and ecu’s that you cant do with MB Tool lonely. For example some w210 eis or Sprinter 906. You should have both VVDI MB Tool and VVDI prog. Or, if you have to buy some tool again, Simon Touch is the best, but its more expensive.


cgdi mb VS vvdi mb in the aspect of FBS4:

the difference between CGDI and VVDI in FBS4 is as Follow , CGDI can read FBS4 keys and knows if its in a working status or key is damaged , CGDI can read EIS FBS4 and knows if it working or not working ,However VVDI can not Detect FBS4 . on the other hand CGDI never claimed that it can make calculation for FBS4 . Only Read to know the status . Out of the subject No one was Born knowing everything at one point we all asked for questions to know. Respect


Both CGDI and Vvdi MB are a great comprehensive solution comparing to what else is available out there. In my opinion they’re the two best for keys maybe along with Diagspeed but much far ahead than AVDI (for keys).


AVDI fbs4:

The most new benz cars have fbs4. Avdi cannot make fbs4. You have to go to dealer. The newest cars to make with avdi are from 2013.


diagspeed fbs4:

diagspeed can read Mercedes FBS4 key info.

Read FBS4 ezs w218 w212 w166 w246 by can full data 2015.


FBS4 key solution


Fsb4 & fsb3 key:

Timings FBS4 comparing to FBS3 totally different, data exchange different so no chance using a FBS4 key like FBS3.


FBS4 applicable models:

Applicable Models: April 2013 to Present, Model W212; July 2013 to Present, Models 166, 207, V212; September 2014 to Present, Model 218; November 2014 to Present, Models 117, 156; April 2015 to Present, Model 172; MY-AII, Models 205, 217, 218, 222, 231.

MY2013, Model 166 with Code 803, Models 207 and 212 with Code 804.


Also, you can check SA Codes on vehicle data card or use any suitable online vin decoder to see SA codes related to your vin. You are looking for the presence of SA code 803 or 804, depending on the Model this means vehicle is FBS4 related.


FACT: Be sure . No device can do fbs4 yet . Only MB dealer can do it


I’ve been able to order fbs4 keys for years, got them direct from Mercedes. It car still has to go to dealer to be programmed.


Dealer can order a pre-programmed FBS4 key, similar to older models, but most dealers won’t. Huge amount of paperwork/protocol from FBS4 technician and scrutiny from Benz corporate…Needs to really be a true emergency: IE car stuck at bottom of Grand Canyon and only way out is airlift or get a programmed key…Or maybe easier is DBS4 technician and dealership owner is related to you!


so if i understand well, vehicle has to be towed?


No…dealer can order programmed key (3 to 5 days to deliver), hand it to the customer and car will start, same as any older system. The difference is in the key ordering procedure…FBS4 key needs much more scrutiny of paperwork, authorizations of parts managers and FBS4 technicians etc…most dealers do not want to go through this big procedure and liability, so they tell everyone to have the car towed in and key programmed with diagnostic tool which is a much more common (easier) practice for them. Personally my opinion is that Mercedes corporate is encouraging the dealers NOT to order the programmed key unless total emergency and no way to tow the car in…
