coding/programming ME f/98 SL500 ???
 

The ME controller in my '98 SL500 has been diagnosed as not communicating with a shut-off valve (the car seems to run fine, but the MIL is lit, and comes back on if cleared).

I have obtained a used ME (same part number: 021 545 24 32) from a '99 CL500.

My MB dealer tells me thier software has been "upgraded" and it prevents them from clearing the existing VIN programming in an ME unit - and that they now have to order the MEs from MBUSA and they arrive pre-programmed to the VIN they order.

My independent shop uses the SNAP-ON scanning system to read and program MEs... and they are willing to try to download the info from my old ME and upload it to the new one - but can't be sure of the results.

Anyone have any advise that I can pass on to them about "unlocking" the 'new/used' ME so that it can be fully programmed for my existing VIN?

Thanks,

What you want to do is technically impossible. By technically, I mean the system was designed to marry the DAS security system after 40 key strokes and can never be moved to another chassis number. The variant data that can be loaded into a new controller to work in your car is quite a different concept than the security issue you are facing.

If you wish to use that controller email me and I'll tell you what is necessary.
