i've been getting low coolant warnings for the last couple of days.. theres no signs of leakage.. i topped up the coolant a few times (first time it was very low).. went to bmw today, they put my VIN number in their system and then told me its a common fault with the most 3 series models.. i personally believe its the iDrive problem.. they have asked me to leave my car at the workshop overnight.. i'l update you guys as i hear from them!
