Airbag Sign turn on in the morning...

[penasenja]

Dear PMers,My E39, every morning, when i start the engine, the airbag sign appeared. After a while, i switch off and start again, the indicator disappear. I discover that the light will appear when the car is in cool condition i.e morning. I went to Cameron Highland, and the light is on all the time even though i restart a few times it wont disappear, until i came down to Tapah, switch off, start again then only it disappear.Just wonder if anyone who experienced the same? Which part need to be replaced? Tq

Mine is having the symptom too..My mech diagnosed mine and told that the a.bag firing circuit under both front seats are faulty.. So, need to replace them but until now i havent done anything yet..The bad news is the a.bag s wont come out in the case of crash.. I guess u have to undergo diagnostics to ascertain the faulty parts..I just drive my UDM everyday despite the warning light keeps disturbing my sight since i love it very much..Give it a comprehensive diagnostics bro...cheers

Hi Zul..its been a long time...hehehe

if your car equipped with the passenger seat mat sensor then have it check...

the best is to have the car plugged-in to the GT1 and see whats the error code...from there it is easier to diagnose...

Sounds like the Airbag's seat occupant detector grid under the seats. These fail all the time.

try unplugging the connectors from under the seat sensors,clean the connectors and refit and see if the light goes out.sometimes a little effort can save mega bucks......

I have the air-bag sign light on more than a year, normnal mechanic will erase the error for you, can't lasting. Problem will back again. Finally resolved by Auto Bavaria. This is related to safety, go to Auto Bavaria !

My 525 airbag is on too. After plug in the diagnostic and start the engine the light is off. After a while it came back. Recent check using diagnostic in Bukit Mertajam, it indicated my driver side Seat Belt Tensioner. I was told it will cost rm600 to rm700. I notice that after unplug the diagnostic the light is off but when I plug my seat belt the airbag light is on so i'm pretty sure it is SBT issue. How possible can I 'service' like probably the connector before I have to change the unit? Anybody who has similar problem and solve the issue can recommend the workshop?

Guys,

Thank your for your kind advise.... well, i did diagnose before, but the mech cant really tell me which part fault actually. He just mention a few possibilities... its hard to change part by try and error principle... its BMW part maa, not wira or iswara....
BTW, most of u guys saying that it seems like something related to wiring/circuit under both front seat. I'll take advise from moots first, by unplugging the connector, clean it... let see how ....

Tq....

Just to update status of my airbag issue. Sent to Naidu to check and clean the the connector first and ask him to reset. Walla ....solved ! Save save save.....Tq Naidu

But he can't save my rear power window. Ketuk2 no jalan and cannot service so have to change to use motor and arm.

Bro, how much the cost for rear power window that you have changed?

RM550... reasonable? Sound expensive. Not sure how much if it is new. Don't have time to check it out. Actually I don't mind not to replace it for now but since sudah buka...go ahead saja la

Taiwan window lifter only cost RM240 but not smooth like ori one.

 

[zidee]

How much is new ori? Should have change to Taiwan instead as we hardly use rear window. Nevermind.

 

[tkk]

i'm having the ori power window or lifter... interested PM me... i will definitely give you best prices
