Would you mind posting the software version of your stock chip?
The software version will be a number printed on the label of your stock chip and for the 175 DME, common versions are:
1 267 355 773
1 267 356 346
1 267 356 378
My chip is made from the latest version shown above, and should replace the other two without any problems. I'm curious if any of you have the other versions, and especially the 1 267 356 346 version as someone who bought my chip recently is saying that it does not work in his car properly.
Thanks,
Mark
