Alguien sabe algo de esto, lo habeis probado, funciona???? (yo no puedo probarlo que no tengo el coche en casa) Os dejo la direccion para que podais leerlo mas claro: http://www.ultimate-bmw.com/bmw_knowledgebase/bmw_obd_and_fault_codes.htm BMW OBD (On Board Diagnostics) and Fault Codes Last edited/updated on 8/31/04 There are two engine management systems used on 92-99 BMW's, which differ in significant ways. They are: OBD I used on 1992-1995 models OBD II used on 1996-1999 models (note: some 99 models are E46 BMWs) If you have a BMW car with OBD II engine management you will need to purchase a fault code or scan tool reader in order to utilize the BMW codes below. If you have a BMW with an OBD I engine mangament system, then you can read the fault codes from your BMW as follows. 1. Turn the ignition key on and fully depress the accelerator five times within a five second period. 2. After this, the check engine light will go through a sequence of: staying on for five seconds, go off, stay on for 2.5 seconds, go off for 2.5 seconds. 3. After this the fault code will flash. The BMW fault code is a four digit number, however your BMW may display more than one fault code. In this case each code will be seperated by a 2.5 second pause. After all codes have been displayed there will be a .5 second flash and the light will stay off. The table below lists some of the fault codes that could be displayed.
