Huh?Sorry mate, a OBDII scanner is not going to help with the MB-Euro 38 pin connector.
The OBDII-to-38 pin adapter plugs won't work on the MB.
The laptop thing - since the 38 pin W210's are rare here in the US, since we had OBDII - there are some that have used Carsoft 7.4 and the 38 pin cable.
FYI---------------The manuals are good!!WHICH IS THE MOST RECOMMENDED READER, AND ARE THE MANUALS ON MERCEDESMANUAL.COM ANY GOOD
