Hello all,

These days I tried to upload a simple Stage 1 to a friend. I used MPPSv16 because I know it works with ME7.5. I have remapped my car a hundred times with this MPPS.

After several unsuccessful attempts to read and remove the fuses the file was taken. Then I changed the file with WinOLS and attempt to upload it to ECU but unsuccessfully. After some attempts with immo bypass yes/no and speed options Medium/Slow it end with an error "ECU not found".

All good so far but now I can't even read ECU ID and VCDS do not respond.

What could have happened? The car starts without a problem (for now).

Thanks.
