My dealer was cool with it but it's really up to them to warranty it or not since it's not covered from BMW or Dinan's warranty.
AGREED .... but most dealer will just take your car with no problem since its DINAN.
having your ecu tune by other manufacture and bring it in they will REG FLAG YOUR CAR SO FAST...
since DINAN is partner with BMW.. they dont usually say anything..
