SAM programming

Question by roadkill posted 11 months 1 week ago in 2003-2009 (W209)

Hello,  I just got a Mercedes 2005 CLK500.  It has a bad front SAM unit, the one by fuse box drivers side engine compartment.   If I get the exact part number used replacement SAM,  do I have to reprogram it?  If so, can I do it with the icarsoft MB2, or does it have to be done with the 'star'  scanner only mercedes shops have? I have heard good things about the icarsoftMB2,  but cannot confirm it the right one for the 2005 year.   I want to buy a scanner in any case, and need to know which one will work for this car.   

Thanks in advance,
