[QUOTE="anaksarawak, post: 675758, member: 4851"] Hope you keep the old motor as I suspect its still okay. The other issue I heard of or read from E90 uk forum is due to low engine oil or its too old. Also do check your wires to the valvetronic ....................from uk forum [COLOR=#000000][FONT=verdana]my faults are cured found out that the engine ecu cables connections are bad So I changed them therefore the adaptation worked for me [IMG]http://www.e90post.com/forums/images/smilies/happyanim.gif[/IMG] also made an ecu update aswell an ecu reprogram to cancel the catalysator monitoring sensors now my car runs with no problems and without cat. And many many thanks to elie335 for helping me to find that brilliant mechanic who cured my car lol[/FONT][/COLOR] [COLOR=#000000][FONT=verdana]Attached Images[IMG]http://www.e90post.com/forums/attachment.php?attachmentid=537667&stc=1&d=1307742278[/IMG] If for any instance the cam shafts or valvetronic motors are moved from position, the calibration is needed. without doing this you risk damaging the engine internals Before it was impossible to perform an adaptation eventhough the error was "valvetronic adaptation" it wont erase from memory and wont adapt it states that "fault is currently present" and "unable to store learning values to eeprom" so it was a cut in communication with the ecu when changed the cables performed the adaptation it learned the positions the tool was an original gt1. also took advantage to clean the small oil pipes that lubricates the cam and the vaccum pump with new gasket. No workshop was able to properly diagnose even the dealer diagnosed a new ecu [/FONT][/COLOR] [/QUOTE]
