Hi everyone. i really hope someone can help me with this. My 2012 520D F10 starts up and runs for around 20 seconds then just dies. I recently had the dreaded timing chain replaced at a great expense and really don't want to spend any more money on it. i had it plugged in and it came back with the following code
801C60
ZGM No flexray initialisation
801C20
ZGM central fault memory full
Would anyone know what these mean? and maybe a fix?
