For the first time,just crank it longer to start.friends i need your help please
my car is a 320i 2003 ms43
today I made my first attempt to change the software for version 69, my original software was 56
I downloaded the version 69 file and wrote it with the ms4x tool, the car started without any problem
but if I open the file in tuner pro with the XDF Siemens_MS43_MS430069_Community_Patchlist.xdf
and made some modification, for example activate the patch for immobilizer bypass and check sum bypass patch and make full write again the engine only cranks but wont start
already try removing the immobilizer patch and only use the check sum bypass patch and it is the same result, engine only cranks but wont start
I want to use the immobilizer patch since my key stopped working to close the car and open the trunk, so I bought new keys which I could already configure to work with the alarm but obviously the engine does not start with them, I want to be able to use them to start the car
I would like to know what prevents my engine from starting when I apply any of the patches, I don't think it's a problem with the check sum since the temperature needle stays on the blue side
please help me
yes, i already do it and dont workHave you tried clearing all adaptations in the ecu, to see if that helps?
I believe if the tps adaptation error is active the ecu won't let the engine start.
