Hi shazoo,
I recommend SD connect c4, go to www.obd2tool.com, there are two types of SD
connect(normal and best quality) choose one, you can also get the SCN coding for
$100 from this website.

diagnosis-tool.html....waiting for your honest advise

Ede thank you for your advice,yes me too waiting for Fix reply as for me I am focusing
on german brand only because we have here only germans and japanees cars only no
amarican no french nor sweden so looking some one to advise me who is specially
familier to audi bmw porsche mb

Aobd2shop, choose the one with laptop and tell them to install the software before
sending it out...
our maxisys is very good at diagnostic but service and programming function for MB
are not fully covered yet... so if you do more programming C4 is the best for now, it
also does key programming...
You will need SCN coding which cost appr $100, discuss with the dealer about this.

Fix you have done programming for F series sucessfully so now please share the
percentage you will give to this tool?

95% , still a little bit problems...

 So far, so good. All the series "F", that I need to do code/programming work great, excepted one. That was a M550D. All the other have work great.

Great pedro
