Airbag Light came on after regulator repair

Hi,

I just brought my car to replace my window regulator and right after that the airbag light came on. They told me to bring it into BMW dealer to reset it. Will they do it without running any diagnostics? I don't want to pay extra for diagnostic testing. Thanks!

Get the light reset by your Indy. Then if it comes back on after that then you may have f$&@ed the airbag in what ever door you played with. Did you disconnect the battery before pulling the door apart?

My original regulator was broken some time back and I brought it to my mechanic to fix it. My mechanic replaced the broken regulator with an aftermarket part that I supplied. Turns out the aftermarket part didnt fit very well so they left it in there to hold the window up and disconnected the motor. After I picked up the car from them, the airbag light came on and they told me the reason was becos they disconnect the motor. Once I get a new regulator fitted in, it would be fine.

Last week I found a shop that does only regulators and windows. They supplied the part and put it in too. They are the ones that told me that the airbag was not disconnected only the motor. But when my other mechanic replaced the original one with the aftermarket one, they didnt disconnect the battery, that's why the airbag light came on. They told me to get it reset at the BMW dealer. He said sometime the dealer would do it for free or charge a minimal amount.

What I am wondering is if the dealer would need to run a full diagnostics to determine that everything is running fine, or can they just reset it.

I would just get it reset by an independent BMW specialist and if it appears again then something is wrong

The light is probably on because they disconnected the airbag while getting to the regulator, and did not disconnect the battery first. That is normal for the airbag in this case. They should reset the light for free.

The dealer will want to do a "full diagnostic" because he doesnt know what has been done in the past. It is still just a scanner reading and shouldnt, but probably does, cost at least an hour labor. The indy that took the door apart should be the one to reset it, but it sounds like he doesnt have the tool. You can buy an Peake SRS reset tool for $119 new and $80 or so used on ebay.

I agree - your Indy made a sophomoric mistake. They should reset the airbag light, for free.

Just a few weeks ago, I ripped my driver's door apart. I read the DIYs here and every single one of them warned against connecting the battery with the airbag disconnected (and vice versa, disconnecting the airbag with the battery connected).

It's a junior (and unprofessional) mistake to fix a window regulator & have the airbag light on and not reset it before handing the car back to the customer. The mechanic could have done it right and you wouldn't have this problem now. It's wholly their fault.

It's really that simple.

Oh, and a bit of garlic helps ward off the demons!

Hi,

Thanks for all the replies. My old mechanic is 3 hours away so it would be a hassle to go back to him just to get the light reset. I found a near BMW specialist and they agreed to help me reset the light. Will update when I get it done.

100+,

Whether you drive a Honda, Toyota, BMW or Volvo etc, the SRS works like this:

- With the battery connected and even with key out of ignition, the SRS computer still monitors all SRS components for proper functioning. The reason for this design is that: even with key out of ignition, if you sit in a car waiting for someone and accidentally get hit by let's say a drunk driver, the airbags still deploy to protect you.

So when one component is disconnected while the battery still connects, the SRS ECU registers a fault.

- So the Repair 101 principle is: whenever d/c an airbag module, always d/c battery first, replace the airbag sensors etc., then reconnect the battery.

The GT-1 requires one to run a full test of all vehicle systems (5 min tops) before allowing the technician to work on the car. Fixing the problem would take 6 min... with a GT1. Not sure about the other options available.

It's good to know how much it costs.

If I were faced with an accidentally-tripped airbag light, I'd strongly consider putting that $85 toward my own set of reset tools.

But, that's just me.

Interesting.

That bolsters my contention that (in many cases), the tools are free.

The OP, for example, could have stayed at home in his pajamas instead of driving to the BMW specialist, paid (about) the same amount of money on the net, and reset his light himself.

This can/should be used as a lesson learned for the next person with a regulator-repair-induced airbag SRS light!

Yup. I often do Bimmerfest in my jammies!

BTW, someone today gave another woeful story about disconnecting the airbag without first disconnecting the battery.

I think I'm going to keep track of the next twenty or so and put them in a list so that we can show the next person with the same problem that they're at least in common company!

unplug the battery!

I got tired of reconnecting the airbag each time I needed to plug the battery back in and advance the window for the broken window clip DIY (and also a little nervous...) and sure enough - Airbag light. Lesson learned. Tried leaving my car unplugged overnight, hoping that the temp airbag battery system would die but no luck. Time to sweet talk the dude at the bmw dealer parts counter and see if I can pull off a freebie...

For the record, it happened again today:

I don't think something major's wrong with my Airbag system. Could it be that some sensor has been triggered by the Actuator replacements.

Can this be reset by an OBD Scanner/Reader or I need an SE to do this ?

Appreciate what you guys think !

airbag light fix

Hey all -

I fixed my airbag light using a cheap part I bought on ebay from Hong Kong for $30 delivered (took about a month to get to me). It worked on my e46 and included the e36 adapter. It just plugged in and hit reset and I was good - couldn't have been easier.

Just go to ebay and search "B800 SRS Airbag Light Reset Scan Tool for BMW E36 E46". Beats the $100+ dealer and specialized parts I see discussed in these forumns.

Cheers -

Dustin

I know Autozone will connect with an OBDII to help diagnose, can I reset it with that? Or am I SOL???
