Most vehicles will display a warning symbol on the dash and "level control system malfunction" or "chassis" warning message on the idrive display. Any good BMW specialist should also be able to remove the dash warning messages. We work with several specialist coding companies who can offer a remote coding service at discounts rates for Conversionsmart customers.
