aid

Good I am new and I do not understand the forums well, but I would appreciate their help
since the following happens to me:
Mi 307 year 2007 xs 2.0 Premium nafta .. I throw mistakes the Bsi (antipolution, defective gearbox. Excess tire) I would like to know how to restart the BSI? They told me that from a fuse but I do not Restart ... I followed a tutorial ... the car does not fail only the BSI throws errors ... it was fixed everything ... but I do not want to take it to review and that they lie to me ..
