I purchased the CGDI prog MB two weeks ago. It’s a good key programmer for Benz owners. All the goods I received including CGDI MB Multiplexer, NEC Key/ IR Adapter, OBD & USB cables which shipped from UK without Tax.

 

First simply sum up what it can do:

Add Benz car key fast

Support MB all keys lost

Calculate the password online

Work with BE key and original key

Support more old Mercedes cars key programming by OBD

 

I also impressed with the special functions it brings:

Support ECU renew on these models at present:
ME9.7, MED17, CR3.xx, CR4.xx, CR5, CR60.xx, CRD.11, CRD2.xx, SIM266, SIM271DE2.0, SIM271KE2.0, SIM4LE, SIMELKE
Support Gearbox Renew on EGS 7G
