Sean.Robinson Report post Posted January 5, 2011 Hi does anyone know what these codes correspond to; 4152 and 410C. I've just ran a check out of curiosity so I'm not sure how old they are and have just reset them to see if they re-occur. Either way I'm I would like to know what they mean however neither a search on here or google has been too fruitful. As always any help is much appreciated Quote Share this post Link to post Share on other sites

mit Report post Posted January 5, 2011 Aah yeah just realised you have a diesel - they don't have diesel E46 models in USA so they don't list the codes for them! Quote Share this post Link to post Share on other sites
simonlpearce Report post Posted January 5, 2011 http://www.endtuning.com/bmwcodes.html Both of the codes point towards swirl flaps, so yep i would suggest removing/blanking them ASAP to avoid needing your engine rebuilt! Quote Share this post Link to post Share on other sites

I should think its been done when it was M3ed. They might have removed the motor that controls the flaps completely, leading to that open circuit error. I just removed the flaps themselves so the motor is still there doing its thing complete guess tho lol Quote Share this post Link to post Share on other sites

Sean.Robinson Report post Posted January 5, 2011 ye i blanked the swirlflaps myself when i first had a problem with them, figured whilst in there may as well remove the problem entirely. feel a little silly now but my mind is at ease, thanks for the help Quote Share this post Link to post Share on other sites
