Hello mates


I have this Passat 1.6 FSI CC with MED9.5.10 ecu 0261s02286 .

This ecu has permanent P0601 internal control module error Checksum . Car starts fine but just permanent fault .

Problem is in Eprom 95080 in adress 040-07F 100%
It seems like a checksum error .... but my problem is that in these lines it's also the Immobilizer of the car!!

Can anyone help with this fault? Is it fixable? Or is there a way to make the car virgin and write it? I have already tried 00s but nothing....

I can make car immo off with a different file and it works 100% !! But client doesn't like immo off :) That's why i'm looking for a different way ......

Thanks in advance
