Lol taking my time and doing it nicely on someone else's car...... one of mine? A lot faster to do hahaha.

AFAIK the occupancy sensor can trigger the airbag light, as it is part of the SRS system - one sensor fails and it will throw the light on so you get it checked out. So it may be the occupancy sensor or the seatbelt sensor that's throwing the airbag light, either one shouldn't be hard to fix.

Rear wheel pads may just be sensor wire not connected, or your rear pads are too low and need changed, easily fixed.

Fuel level sensor won't have anything to do with the airbag light.

As for the timing, well stranger things have happened but I really don't think changing the battery has caused a single one of these issues to develop.

As mentioned above, more than happy to get my hands dirty if you want.

Sounds good, so how much it gonna cost me in total?

Yes, we need to know what type/year the 320i in your profile is @moneygoddy.

But without knowing that we can all tell you to spend nothing more at the mechanics you've been to.

You need the error "codes" read from the onboard computer. A BMW specialist (original dealer or independant mechanic) with the correct computer equipment can do this for you, as can some private individuals such as @Mad_Max offered above.

If you take it to a specialist you should ask for the codes to be read and to be provided with a printout which you should then post here for comments. Make no commitment to further work. This shouldn't cost more than $80 and IMHO should be free (rebated) if you get any repair work done at the same shop. To get the codes they need to connect up the computer, read the codes, clear the codes, drive the car, connect up the computer again, read the codes and print all the results. A charge is justified, it does take time and equipment (although very little skill) to do it properly.

If you can find somebody private to do it for you then you should ask them what beer they like.

Two posts & still we don't know the actual car. We are all wasting out time without that knowledge - how long is a piece of string?

Thanks for your reply guys,

The model is 2006 320i 5door. The guy I went to said he is getting errors of passenger seat occupancy, rear wheel pads, fuel levelsensor. I don't really think fixing these will sort out the airbag and seat belt sign off. Car was absolutely fine before getting the battery changed and both of these signals came after I got the battery changed I mean right after I got it changed. I will try going back to the same guy who changed the battery and ask him look into it. 

So should I go and get it checked from BMW specialists? I was quoted $500 for occupancy sensors and rear pads as they were coming on the system to be replaced, still that mechanic wasn't sure that will fix those lights lol. 

Hi guys,

I recently got my car's battery changed from a random mechanic. Right after having it changed the airbag and seat belt warning light turned on. I believe these got triggered when the battery was changed or it just happened at the same time, I don't know. I read online that after changing the battery, you need to update the system to say that the battery has been changed but it wasn't updated. So I went to a new mechanic as the service was due and he found that the Seat Recognition pads, and the rear wheel pads are triggering those lights!!! 

I am just confused on how come the lights turn on right after changing the battery?
