I have a 320I E90 2007. The flashers are ok for 3 secs then flash fast either side and the bulb warning comes up, I have cleaned all the sockets and replaced the bulbs 21w 12v still happens, they are all working the same brightness and my scan tool reads all lights ok and no short circuits, I clear codes and try again and same happens.
second problem is the Red car on hoist light comes on as well with no warning area, all servicing parameters are ok and insp is in date, would appreciate any ideas
