I had this issue, coolant leaked slowly, approximately 100ml a month. After 6 months of topping up the EML came on with no message on iDrive. BMW eventually agreed to resolve after I had a local specialist investigate. My previous dealer that I took it to was adamant that the recall did not affect my vehicle, even though I received a letter telling me it did which also explained the symptoms.
