96 C280 Bad Diagnostic Module
My 1996 C280 has been running rough for the past year or so. Over that time I took it to a couple of shops who tried but failed to fix the problem. I have now sent it to the dealer and they said they can't diagnose the reason for the rough running because of a faulty diagnostic module. This module is only available from MBZ in Germany for $2500 and is coded to the automobile so you can't just install a used one.
Because the car has 200k+ miles on it, it's not worth spending $2500 just to be able to diagnose the problem especially considering how much it might cost to actually fix the real problem.
Is there any way around this? I would expect the dealer to say there isn't, but with the world's computer hacking capability, isn't there some way to take a used module and "code" it to a different car? Do I have any options outside of the $2500 to fix a car that may not have that much life left in it?
