missbmw 0 Report post Posted June 18, 2013 Hi everyone I have just bought a BMW 325i AC Schnitzer, still getting used to all of its features... The Check engine light keeps coming on everytime I Brake hard while driving. Then the screen will tell me that I need to check the 'Brake light circuit'. There are no issues with my brake lights so wondering what to do? The engine has had a full rebuild so not sure if this has anything to do with it? Thanks all,-confused Gen x Quote Share this post Link to post Share on other sites
