Reasons for CGDI MB“Load File Failed, error code: 27E1”

Here’s the issues for CGDI MB key programmer error: “Load File Failed, error code: 27E1”

Possible reasons that cause the error:

1).  Device fell on the ground and damaged

2).  Take apart the CGDI main unit manually

CGDI Prog MB host is equipped with an encrypted battery. If you disassemble the programmer, the encrypted battery will power off automatically. Benz Monster software refuses to run properly.

What’s more, the battery cannot be purchased separately nor installed by yourself.

The ONLY solution is to send CGDI back to repair.

2000 G500:

BENZ G500 year 2000
Just done a Benz G500 imported from Dubai

2004 W203:

W203 2004 spare key making:
Total time about 13 minute when beginning to programming new key. Read pass NEC key by IR and calculate PSW
Key still working after get PSW.
Done in car.

2004 W203:

W203 2004 spare key making takes about 13 minute when beginning to program a new key.

Read pass NEC key by IR and calculate PSW
Key still working after get PSW.

2004 W211:

W211 2004 year add key ,10 min job!

2005 W203:

Class C W203 2005 adding key on car.
Spare key made in under 10 minutes.

2006 W164:

ML350 W164 2006: Read EZS, add key, write BE key all done in 17mn.

Really fast and i’m happy with the first try on car. Use late software 2.0.0.0
I just plug in the OBD, put key and turn ignition ON and read.

After this step, CGDI will ask only put in EZS and in CGDI.

Just all. PSW query is more longer than 209, about 12mn to get PSW.

2007 W221:

Add Key on W221 2007, i was complete in ~12min. CGDI is very fast
Upload collect data after 2 or 3 min show me PW

2007 w221:

Add key on bench
First try I use VVDI MB
But 2 time upload also failed cannot get pass
So I was change device CGDI from VVDI
1 time upload successful
Good and very fast 10min got pass

2008 W219:

Add key also 15mn OK

2009 W164:

2009 W164 ML450
Key add work
Cgdi 15min
Very good speed!!

2009 W164:

w164 after 2009
I did for testing 2 types of programming _ have got EZS with both programmed keys because customer claimed sometimes EIS works sometimes doesn’t – I have found that connector for immo aerial was desoldered from PCB so when I fixed it – EIS became fully working again – and then I started testing CGDI and made 2 types of programming (all programming on bench – EZS + GATEWAY EMULATOR)
1) programming in case one key is available and adding spare key – ALL OK!
2) programming in case of ALL KEYS LOST – ALL OK!

spare key programming was pretty fast
AKL scenario takes circa 80minutes to get data from EIS and You have to plug in and out emulator key every 5 seconds – I have bought VVDI POWER ADAPTER to pass all hassle on to adapter so You don’t have to watch whole process and move key in and out manually – but it doesn’t work with CGDI – seems adapter works only with VVDI MB and software drives it by adressed pin to switch connection off and on between ezs and key emulator – maybe CGDI TEAM could write a code to their SW and make VVDI POWER ADAPTER useful for all their customers.

2010 W207:

C300 W207 2010 spare key without problem and in 2 minute

(exiting key is BE, so no need server query PSW)

2010 W204:

Part 3: CGDI MB and Mercedes FBS4

No tool can do FBS4 key?

No.  With genuine xentry and daimler fbs server.  Makes FBS4 every day via OBD very fast and easy.

Diagspeed announced the dates of FBS4 solution. But not confirmed yet. The Diagspeed has the reputation of being the best in the Mercedes world to make keys, Reset ECU’s and trouble shoot problems that a normal scan tool can not.  It is worth to take a gamble.

CGDI MB can read FBS4 keys and knows if it’s in a working status or key is damaged

VVDI-MB-TOOL-full-package-2 VVDI-MB-TOOL-full-package-3

Conclusion:

CGDI MB is a good Mercedes key programming tool, as good as VVDI MB TOOL.

How to Repair Mercedes W211 Rolling Code with CGDI MB?

How-to: repair Mercedes W211 original EIS rolling code with CGDI MB MB Benz key programmer.
Rolling code :
A rolling code (or sometimes called a hopping code) is used in keyless entry systems to prevent replay attacks, where an eavesdropper records the transmission and replays it at a later time to cause the receiver to ‘unlock’. Such systems are typical in garage door openers and keyless car entry systems.

How to do BMW CAS DME Sync After New Programmed Key Failed to Start Car?

Problem:

I’ve done 1x CAS2 with CGDI BMW – 2006 E90 Diesel

ELV sync was OK

CAS sync failed, ERROR and would not start

car did not start until i used another tool to do the CAS sync.

Cause:

Every tool can cause cas/ews/dme/dde synch issues on BMW, particularly diesels and you need a good solution to resynch. A very experienced key guy had the same problem on an E91 that had lost synch using AVDI. It’s nothing to do with the tool used, it’s the process.

problem is not to fix synchro, after cgdi you will have synchronize problem with all devices.

They need change data reading algorithm, because after this procedure cas is near dead.

Solution:

I know CGDI isn’t perfect, but it is, in my experience, a useful tool and good value for money.

I don’t even try to use a key tool to resynch ews/dme. Use a good BMW diagnostic and, more importantly, know how to do it.

To synchronize the blank DME to your car, you’ll need a BMW Compatible scanner which has the function to “Align” or “Synchronize” our DME to your CAS.

Below is a list of the most popular BMW Scanner that we know for sure, have the function to do this procedure.

* ISTA

* GT1 / DIS

* Autologic

* Launch X-431

* INPA

* PA-Soft

There might be other BMW compatible scanners, but you will have to check with the manufacturer if they have the function to synchronize the DME to the CAS.

Every scanner has different steps that you need to follow in order to do the alignment. However, in general, this is how it is done:

1. Make sure that your car’s battery is fully charged. (This is important because the voltage cannot drop below 12 Volts during the synchronization.)

2. Connect the scanner to the car either through the OBD2 port or, if the car has a Round Plug connector under the hood, use that one.

3. DO NOT start the car, but turn the key to the ON position.

4. Follow the steps in the scanner to select the model and year of your car.

5. Then go to DME or ECU. (This is usually the section where you check for fault codes.)

6. There should be an option available for “DME-CAS alignment” or “synchronization” or “calibration”.

7. After you go through that process you have to turn the key to the OFF position for at least 25 seconds.

8. Then start the car.

When you are finished synchronizing the DME to your car, it is very important to delete all the fault codes and reset all the adaptations in the DME. Otherwise, you may get an incorrect fault codes or a check engine light.

Ista-D is ideal, but it’s hardly a 10 second process.

How to use ISTA-D to do a Sync after battery reset?

Clear dme/dde fault codes

Disconnect battery.

Wait 20 mins. Count it. Don’t be impatient.

Reconnect battery.

Ideally, connect battery support unit.

Check no fault codes. Do not try to start car.

Do cas/ews to dme/dde resynch.

Ista D – service functions. Just follow the instructions.

Click on Function Selection, then under Service Function select Drive, Engine Management (ME9/MED9), select Adjustment in the middle column, DME-CAS in the right hand column, then the middle < > double arrow a list pops up and on the list “Note: S1214 NGCAS / Start Value Status”.

There is a description of the error, then press right arrow.

Option 2 to reset the code (Start Value calibration), then the right-hand arrow

Switch on terminal 15 is shown (which means put the key in and switch on the ignition, but without the engine running (well seeing as the car wouldn’t start that was a no brainer!) Right arrow again, and it popped up, scarily, with 2 errors with a numbers like: <00062538> with <0000000> below it, which I assumed were the mis-matched data from the control module/key – cancelled both these and it then reset the codes, and asked to turn off the ignition (Terminal 15 is off), wait for the main relay to drop out (so left it 20 mins), then the car should start, which it did.

Locked it up and left is another 20mins and the tested starting again to be sure and it worked!

bmw-cas-align-ista-d-5  bmw-cas-align-ista-d-7 bmw-cas-align-ista-d-8

Working experience:

I’ve done many e60 cas2 no issues, more than i can remember. only 2 times crank no start and needed resync. 1 vehicle is because power died from bad battery customer did not tell me battery dies after few minutes, and 2nd time i did add key and got error, i usually never do add key and always just generate and works good, so maybe that caused.

both times fixed by disconnected battery both + and – and let sit for 20 minutes, reconnected battery and used ista/d to resync. car starts right up after sync.

Can I use OBDSTAR X300 DP on BMW CAS2 CAS3 CAS4 via OBD?

Is it possible to add one key to BMW CAS2/CAS3/CAS4, using OBDSTAR X300DP PLUS yellow version?
obdstar-x300-dp-cas2-cas3-cas-1
On cas 2,3 we use tools like usually VVDI2, CGDI BMW.
On cas 3+ with working key!! If it is AKL (all keys lost), you need to pull ISN code on dde or dme!!!! for registry a key you need downgrade the cas, register key and after backup.
On cas 4 Obdstar x300 dp is not working on obd !!! Just to Block or activate key !!!!
