Hi all!

Recently got my hands on a nice BMW 323 Ci and have had the pleasure of trying to get some things sorted on it.

Got it fairly cheaply so I expected problems to be honest haha

First up was the rear breaks sticking, had them off and cleaned them up and all is good, then the handbrake drum was pretty shot, so cleaned that up and now that's all perfectly fine!

The only thing that's confusing me, if that the airbag light is constantly one!

I tried connecting my OBD2 kit to it, and It read a couple of error codes, but nothing that I hadn't already sorted, so reset them and they have not returned since.

So im still stuck with the damn light on!

Anyone able to shed some light as to whats causing this?

Any common problems with sensors, looms etc?

Cheers!

Keith

Its the occupancy sensor under the passenger seat mate. Its a common problem, plenty of cheap fixes on eBay dude. Welcome to the forum.

ahh sweet :)

so if I bought something like this http://www.ebay.co.uk/itm/BMW-PLUGnPLAY-OCCUPANCY-MAT-SENSOR-AIRBAG-BYPASS-UNIT-E46E36E38E39E60E65M3M5Z3X5-/230734780963?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item35b8dd5a23 , would it fix it?

do I still not need to reset the Airbag error codes with a SRS reader or something?

Or should it be all good after fitting this?

Cheers!

Keith

welcome

Should be all good, cant see the link at the moment. Im on my phone right now. There is a guide on here somewhere, ill dig it out for you tonight mate.

Here you go mate

Pics on the ebay item are pretty straight-forward... You can make it slightly easier by removing the front two seat-bolts and loosening the two rear ones and tilt the seat upwards !!

Hi and welcome mate...

Helloooo everyone again haha

Ok, so, I have just fitted a sensor 'fixer' as you can see here.

Only problem, is the light is still on the dash!!

Im sooooo confused haha

We got sent 2 by mistake (one as you can see in the pic, and one without the block on the end), but nether work!

Ether that, or something else is causing the problem...

Can anyone help by suggesting other places to check?

cheers!

You can usually clear the AB light (after the bypass is intalled) by either a dash comp reset, or by disconnecting the negative from the battery for quite some time !!

Did you disconnect the battery BEFORE you installed it?

How do you do a Dash Comp Reset?

And anoyingly... no, I forgot to disconnect it!

Try the battery disconnect first - overnight if poss but an hour or two should sort it, if not I will guide you through a Dash-reset ok?

Bear this in mind mate - Disconnect the earth-lead to battery before messing with a BMW's electrics ;)

ok matey, thats fine with me!

Ill try it now :)

thanks!

Ok, I took the battery off for 3 hours, and then after that the light was still on.

Then left it off overnight, and its still on :S

Any change of a guide to doing a dash reset matey??

Cheers!

BUMP!!

anyone able to help with dash reset?

Do you still have codes showing?? although the occ sensor is common it is not always the cause, see what the codes say and replace the offending part, mine was on because of a faulty seatbelt tensioner and it was then a pain to get the light off, it took 4 or 5 attempts to get in off. good luck mate hope you find the fault.

take the air bag bulb out the dash :lol:

Here are the codes.

Ones for the MAF, one im not so sure about!

P0101 which is the MAF I believe.

P1622 is the other one that im not sure about!

Really pecking my head this now haha

Wouldn't be so bad if I knew which part was causing the problems :s
