Hi, the airbag light is on in my 2003 2.5 BMW z4. I select the car, I see:Auto scanControl unitsI go to control units, I see:DriveChassisBodyI go to Body, and read codes, no codes. I clear the codes, it says clear codes sent, but light stays on. I tried all the z4 types that might apply.Why can't I read or reset this fault? It is a new reader, I have just done the updates.Thanks -

Hi, can anyone help me with this?? I have emailed support, no reply.Further info: My mechanic can reset the code with his snapon unit. The 802 seems to recognise the airbag module, it gives me “ECU INFO” and the BMW part number is shown as 6938264.But no codes appear and if I reset, the light stays on. -

Hello, thanks for your reply, but what you say is not consistent with the advertised features:http://www.auteltech.com/Professional%20Scan%20Tools/393.jhtml"One tool can do it all-reads and clears trouble codes on either the basic 4 systems (engine, transmission, ABS and airbag) or all the systems"And now you are telling me airbag is not supported?? Am I misreading something?? -

Hi, sorry that we didn't make it to be more clear. Faults in air bag is not the only reason that air bag light is on. It could be caused by faults in other system/module as well, for example SZL. So if there is no codes showed in air bag, we might need to read codes in other system and check. -

Thanks for the explanation. The faults were:1. Passenger occupancy (seat mat) sensor,2. seat belt buckle sensor.So these are not considered faults of the airbag system? What autel equipment would I need to deal with these? -

Hi, these faults are related to Air bag systems. Please refer to service manual to fix these faults first. -

Ok, let me try to explain this very simply: These were temporary faults, which have been solved by wiring in bypass units. So I then needed to reset the codes to switch the light off. So I bought an Autel MD802 which "reads and clears trouble codes on either the basic 4 systems (engine, transmission, ABS and airbag)"And you have now confirmed that these faults are related to the air bag system. But the MD802 CAN NOT read or clear these fault codes. My local garage could read and clear them in a few minutes with their snapon system.This obviously does not make any sense whatsoever. So, have I missed something in the operation of the MD802 in my attempts to clear these codes, or is it being advertised with features that simply do not work????And if that is the case, what equipment do I need to buy which actually really does read and clear airbag faults??? Please!! -
