started my 120d at work tonight and the DTC/DSC warning lamp was showing but was yellow not red. The lamp is a triangle with exclamation mark inside the triangle and also an exclamation mark on the righthand side. This lasted for a few secs and then the brake warning came on. These went off after a bit on the main display but then left the smaller warning lamps lit on the larger dispaly. I am not sure if there is a fault as the car seems to be driving fine.
I am after advice as to how I can tell if its a faulty/bogus warning and if so how I can get rid of it
