CGSULIT SC530 OBD2 Scanner All System Code Reader for Mercedes Benz/Sprinter/Smart, Bidirectional Diagnostic Scan Tool with 30+ Service, ABS Bleed, Oil/EPB/SRS/SAS/TCM/BMS Reset, Auto VIN, Free Update

Plug, analyze, reset just about anything on my 2009 C350.

After getting an understanding of the functions it is pretty easy to use. It gives accurate assessment of faults and can save a lot of time and money. The special functions where you can test and get live data are awesome! For Airmatic you can test every valve and shock/strut individually. You can also test for leaks at reservoir, valvebody, and compressor. provides great recommendations for what might be causing the issue. If you have an Airmatic....you understand. Unit is centered around Y and N keys. Just remember to "N" your way out of screens. I am truly satisfied with it for my 2006 S500!. Just lower the update fees! Hahaha! So i can use it on more vehicles.

I coded the fuel injectors on my Mercedes. I have $300 scanners that would not code the injectors even though it was advertised that they would.

It does exactly what they say and really helps you diagnose problems...I recommend it highly....

I ordered the SC530 from the CGSULIT site directly for Nissan/Infinity, it was shipped thru Amazon, of course, typical amazon shipped the wrong one. Amazon sent me the unit for BMW, These people have unsurpassed customer service. Once they were notified, I had received the wrong product. They went out of their way to make sure I got the Nissan program downloaded. They also offered me another model to download for free because of the inconvenience. They then walk me through every step. This little unit paid for itself. The 1st day I used it recalibrating my steering angle sensor Turning off the airbag light since I just put a clock spring in diagnosed the rest of my problems. Saving me hundreds of dollars from buying unnecessary parts. I would recommend these people, because the product is good, and once again you cannot beat customer service. Their customer service is what other companies ought to model theirs off of. I am far from a professional mechanic, and again, this unit makes everything easier..
