I have a 1995 E420 as a project time and time is on my side as it s not my daily driver yet. Hence, instead of throwing parts and seeing if the problem is fixed, looking for a good diagnostic setup to troubleshoot (ideally, looking for a setup that will also with 95 E320 but not at the loss of functionality for M119).
Below is what I found:
Carsoft - No live data for W124. Works for a variety of cars.
SDS - Seems like a good bet if purchased from the right buyer. Expensive, standalone laptop (not trusting it with network connectivity). Variety of cars.
HFMscan - limited LH support.
Snapon MT-2500 - seems to does everything that SDS does but clunkier.
Anything I am missing?
Currently debating between SDS and Snapon.
Can someone post the links (or PM me) of where they purchased SDS or Snap-on setup?
