Mercedes MB STAR  Tools Buying Guide:


works for Mercedes Benz cars&Trucks till 2015.12, reading out and erasing trouble code; reading the real-time data of sensor and actuator; coding and programming. If you would like works well for Benz old models,  C3 is highly Recommended.

“For my car I already have an OBD tool but I need something that will read/reset the Mercedes-specific codes. SRS codes for example.”

“One other section that is not mentioned is that the C3 ,i don’t know about the C4 ,but ,the c3 requires all the cables connected to the car & the Laptop plus possible power to laptop & internet in some case (me) .
The Cables are the Fat 38 pin / C3 cable to Laptop / the ADSL cable/ Laptop connection /mouse (wireless) & laptop power ,to many cables all over the engine or in the cabin ,i didn’t like that at all.”

“For mercedes Benz, C3 and C4 also can do work, in my opnion, C4 work with all the benz and more than C3, but C3 can do benz truck very well, this is advantage for c3.”

“C4 is much stronger in anti-interrupting ability, when C4 tests cars, it’s hard to influence by the environmenr outside, such as magnetic field,noise. C4 is much smaller in the appearance than C3.”

“The biggest difference, i think, is connection wiring mode, C3 need 232 port, but C4 can be used with network port, even wireless.”

SD Connect C4 /C5  and sd connect  C4 PLUS with DoIP

If you want to purchase a “future proof” device that can read old and new cars, then purchase a mb star C4/5 or mb star C4 DoIP.

There are different chipsets (better or cheaper clone copies) on the circuit boards in the SD C4 Connect, so you have to be careful which you buy.

MB STAR C4 Plus with DoIP is needed for some newer cars with DoIP Protocol like W222, supports Benz Cars from 1989 to 2020

“Comparing with  C3,  C5 has only ONE single fat 38 pin cable connected to the Diagnostic port on the car ,no messy wires no where”

“Benz compact 4 SD-Connect is a latest Benz wireless multiplexer. It will connect to the PC by wireless connection.”

C5 that are being sold are mostly FAKE—They are only SD Connect C4  with upgraded housings. Genuine C5 is very pricy.
