great videos! thanks! My favorite quote "Not something you see everyday on a BMW - no warning lights!" 🙂
Thanks! And thanks for watching!
Impeccable timing, just got the SRS light on my ‘01 2.5L today! Thanks, Mark. 🙌🏼👍💪🏼🤩
Glad to help! Thanks for watching!
This worked perfectly on my “zed 3”- I’m from nottingham :) I tried a Bluetooth ODB scanner+adaptor with a few apps but it didn’t work. The B800 was the way to go. great coincidence and timing for this - many thanks! Love the channel.
Thank you so much! Glad I could help.
Really appreciate you addressing this, same issue with my 96.
My pleasure! Thanks for watching!
Solid advice and procedure, I bought the tool and finally solved my SRS idiot light. Thanks 😊
My pleasure! Thanks for watching!
I cant thank you enough. A few months ago I bought the exact diagnostic tool that you use in the video. Annoyingly the instructions do not suggest to connect to the OBD1 port and I had been failing to get the device to function. Iv'e struggled so much trying to get this problem solved. Your suggestion to connect to the OBD1 port under the hood fixed the problem immediately. AMAZING !!!
My pleasure! Thanks for watching!
Can’t thank you enough! Have a 1998 Z3. Light came on & Ordered the unit here in Northern Ireland. (Uk) had the airbag light on. Bought the OBD system & diagnosed seat belt pre tension system. 10 minute fix system reset & has sailed through its annual
M O T inspection test…. Legend
Glad to help! I hear the MOT is tough.
It also just worked for me. My mechanic with more than $10000 worth of diagnostic tool could not fix the Airbag light, but thankfully I watched this video about this Z3 expert and light was reset successfully. Now I only have left brake light and traction control light to resolve.
Appreciate the kind words! Good luck with the rest!
Disconnect the light or wire in a timer delay.
Thank you so much for show how to clear the airbag light!
My pleasure! Thanks for watching!
Thanks Mark!. I got codes from Table 40 related to the driver's seat. Had to do the reset twice, but now they are cleared. Thank you for the information. Got my tool from your amazon link. Not sure what caused mine to light up, since it happened BEFORE I did the seat bushings. We'll see if it pops back up.
It might, just reset again. Glad it worked! Thanks for using the link!
Worked like a charm - Thank You!
Glad it helped!
Thanks for refreshing my memory. Instant success:I originally got the tool after doing the seat runner job, WITHOUT disconnecting the battery !!!There is one typo in the manual where "on=no" or vice versa.
Glad I could help!
Just purchased this on your recommendation my airbag popped up . Only came up with 1 fault followed the procedure snd the lights now out . Handy gadget to have 👍
Glad it worked for you!
Yea, that would have been helpful as I made the mistake of turning on the key while changing the seat bushings and bought a reset tool from Amazon about two years ago. Good video.
Thanks as always!
Just ordered one with the code! Thanks for the video
Thank you and thanks for watching!
Thank you, very informative.
Regards from
Australia
Thank you!
Thank for the advice! Had the light come on a couple of weeks ago on my '98 z3. Ordered your tool from Belgium and it arrived two weeks later. Managed to reset the airbag and I finaly have no lights on my dashboard anymore.
Glad to hear! Thanks for watching!
Thanks for you research!
My pleasure! Thanks for watching!
I have the same problem ☹️ I’ll order that tool next & get rid of it 😃 I’ll be sure to use your link!
Thank you so much! Appreciate you!
@@MomentofZed And, I you!
Well done! 😀
Thanks Walter!
Thanks Mark, I am planing to fix the issue with the airbag warning light on my Coupé. The Z won't pass the inspection here in Germany wth the light on..
Good luck and thanks for watching!
I bought this tool and worked great no more air bag light.
Glad you liked it!
@@MomentofZed It’s very helpful for sure. Now I need to find out how to locate certain pins on my DME to do that fix for my fuel pressure sensor.
My airbag light kept coming back on my Z3 even though I reset it with the B800 tool. I discovered the air bag light immediately goes out when I plug in the passenger seat belt! I suspect it has something to do with the passenger seat sensor but as long as it is plugged in , the light goes out.
I usually need to reset the airbag once a year using the same tool. I have never found any real reason for the fault indication. I guess it is just a bad construction with some glitches in the fault detection circuit. I usually need to do it to pass the yearly inspection here in Sweden as they will not let a car pass with a faulty airbag. Once I had to do the reset while waiting at the inspection station when the airbag light came on when I started the car to drive there. I have a -99 Topazblue 2.0 here in Sweden, purchased the car in 2001 and use it every year for 6 summer months when the weather permits. Have not had any problems, just change the oil every second year. Now my son drive the car whenever he can and love it. He is younger than the car at 21.
Love the father and son Zeds! The airbag light is a funny thing. I think part of it is the age of the components that make up the system.
I bought the Z3 from a private party, with the airbag light on. He said his mechanic could never figure out the cause. After changing the seat rail bushings, I noticed pinched wires. I bought the same service tool, and eliminated the service light.
Causes seem to be the mystery for most of us. But again, under the seat is where the issue often lives as with yours.
I want the green car!
I bought this tool due to me making an error when I replaced the seat bushings. I accidentally had the spindles reversed causing passenger seat to go backwards when it was supposed to go forward and vice versa and I had unplugged one of the seats before disconnecting negative side of battery. I tried to
Clear the code and it was unsuccessful. It through 02 first and then 05
Good video-- thank you. We have the same fault light on our 1997 Z3. Plan on clearing it as well. Has your fault light come back on at all since you cleared it?
Yes. I just did it again. Notorious system on these cars.
Great video! I ordered the same tool but my diagnosis plug has a triange in the middle and not a pacman? Do you know if i can clear my airbag light?
I'd like to explore that tomorrow, I can't look at mine right now due to xmas lights (see tomorrow's video) can u send a pic of the plug to me at momentofzed@gmail.com?
You should do a video on cleaning/replacing the icv and throttle body
I'll look into it- thanks for watching and appreciate the suggestion!
Thanks for your videos. You explain things for us non-technically inclined Zer's. I have the dreaded SRS light and bought the B800. It shows a "firing circuit. belt tensioner, driver's side' fault. I have connected to the OBD1 port under the hood and went through the procedure a dozen times but the fault doesn't clear. The clight stays on. Any ideas? 97 1.9 5 speed.
Have to admit, I don't. I'd take it to a Autozone or other parts store and have them run it on their machine and see what comes up. You may end up having to actually fix the thing. Other option is to return the B800; reorder it and see if the new one will clear it- maybe it's the reader itself.
Thanks anyway. If I figure something out, I'll let you know.@@MomentofZed
@@user-uo8mg9lu1n sorry i wasnt more helpful, let me know if you get a solution.
great video. mine is on too on my 2000 bmw z3. maybe i get one of those tools. also my stability light has come on. any idea how to fix that? thanks for all the great videos.
You should get a good OBD Ii reader to check it out. If you dont have one most auto parts stores will read it for you (at least here in the U.S.) You didn't accidentally turn it off did you? Check that first. Thanks for watching!
@@MomentofZed thanks
mine to and i took it to the bmw dealership and they said after charging 199.00 to check it out that i need to replace the DSC pressure sensors and bleed the brake system. they gave me an estimate of 981.28. Good luck w/ yours. My air bag light was on way before this light came on, and they checked it too after charging another 199.00 and said i need to replace airbag control module and program. that estimate is a hugh 3076.00 so thats probably not gonna happen! Hopefully yours will be something different and wont cost as much. Will i ever buy another BMW ? NO Hell No. Cost too much to fix when something goes wrong. Good luck. I just ordered the tool tho that he speaks about. Lets see if the dealership was just trying to rip a gal off?
@@edythesandefur1298 the tool will reset the light. It won't fix underlying issues. But I wouldn't spend 3k on mine either. Shut off the light and drive on!
@@edythesandefur1298 I had both the DSC problem and airbag light on my 2000 2.8 roadster. The DSC problem was a faulty rear wheel speed sensor, just replaced with a new one. For the airbag light problem it was due to a defective airbag control module. I sourced a reconditioned one on Ebay Germany, cost me about 230 dollars and worked perfectly. Let me know if of interest and I can send you the guys details, he speaks english.
My z3 has a yellow connector on the battery terminal in the trunk. It's broken. Any advice on fixing it. My airbag light is also on, and the battery compartment in the trunk had a lot of water in it. I drained all that out.
Battery compartment water could be from a bad center brake light gasket . Or a leaking seal on the back of the soft top. The yellow connector not sure, I'd check mine but im traveling and wont be home until the 30th.
Can I ask - would takin the seats out bring the lights on? Im currently changing bushes and cleaning the carpet and the light is on???
Yes. If the battery isn't disconnected first ive been told by others that will cause the light to come on.
Recently bought a 1997 bmw z3 in perfect condition but the mph wont go up and just stays at 0 and the check engine light came on but everything else is perfect. Any recommendations on what that may be?
If you dont have an OBD II reader I'd take the car to an autozone or similar store and they'll read the code for free. As far as the speedo goes, I'd start withe speed sensor in the rear differential. This is more than likely the culprit.
I have a 3 series same parts. Code 10 and 11. Reset doesnt work. I never touched the seat buckles..
Double check it, but return it if it doesn't work. Might have to go with a full boat scan tool to get it done.
Mines,20 years old and starting to nickel and dime me to death.Time for the boot!👟
Wish it were just nickels and dimes! 😅 sorry to hear it though.

So do I !
I have watched your videos very helpful but I do need some help my 1998 z3 2.8 needs the fuel tank pressure sensor replaced but can not find and videos on how to replace it. Some pics show it on the gas tank some say it’s on the vapor canister do you have any information on this
Don't have the info handy but let me do some research.
@@MomentofZed Ok thank you very much
@@glennmiller6363 according to realoem.com appears to be on top of the fuel tank near the flller neck.
Yes I have seen that I’m trying get info on how to remove it without dropping the fuel tank. Not sure if you removed the fuel vapor tank if it would give you access to it as I can’t get it registered with the P0451 code I can clear the code it stays off as long as the car is running but as soon as you shut it off and restart the car comes back on.
@@glennmiller6363 here's a thread that says the only way is dropping the tank:
bimmerfest.com/threads/fuel-tank-pressure-sensor.1360167/
Airbag and the yellow triangle center light are illuminated on mine
Yellow triangle is your automatic stability control or "ASC". Try pushing the asc button with the car running. It might just be switched off. If that doesn't do it, get a regular obdII tool on the car and see what code you get. If you don't have one most parts stores will do it for free.
@@MomentofZed button doesn’t do anything for me unfortunately
@@Keepingupwiththekirks get it on a good regular obdII then and you should get a fault code that will help track it down. The cheapy i reviewed doesnt work for other warning lights as far as i know.
Bimmerfest has a good thread on this BTW. The old forums are often chock full of good stuff. They point out a couple of common failure points.
@@Keepingupwiththekirks I'm having the same problem, did you get sorted?
This work for z4 sir? Also do you have to open the hood?
Not sure about the z4. Ill have to check. You do have to open the hood.
Can u clear it with a regular obd tool
Some can but not all, so double check prior to buying. Thanks for watching!
My z3 srs light came on a couple years ago bc I was talking to a girl at the time and her and her two friends needed a ride, one must've been pushing 170 pounds, the other one and the one I was talking to weighed 100-110 lbs, they all sat in my passenger seat at the same time and ever since I think my passenger position sensor has been busted hahahahah
So many inappropriate comments I could make...😄
will the b800 fix a crash sensor relay going off?
Not sure to tell you the truth; haven't had that issue nor have I heard anyone discussing it- let me take a look thru the old forums. Worst comes to worst, amazon will let you return it if it doesn't work.
@@MomentofZed thanks, my crash sensor relay has been making my flashers go off constantly so i had to remove it but removal made my headlights stop working so im looking for a way to reset it so i can just plug the relay back in 97 z3 m44b19 auto
What going on with your side roundel ?
Nothing just keep forgetting to order it. Old age!
I get code 0206 but light still on after reset. It never shut off on cluster. Perhaps B800 connector is bad ?
Hard to say, have you shut everything off and tried a second time?
@@MomentofZed Thanks for replying. The car is an 1998 E39 523i. With round ODB1 connecter in same position as your Z3. lol. I do hear something rattling in the round connector adaptor. Not sure if its just plastic or something metal like a pin that has come loose. I contacted seller and see what they say. When looking at the rectangle connector I see only 5 pins is this the same for you? I will beep test the connector to make sure 1 pin is not disconnected. Yes tried it several times, shut it all off wait turned to position 2 with b800 connected, not connected etc...always same error and not able to reset.
@SuperDarryl138 ill take a look at mine today.
@@MomentofZed Just seperated the ODB1 connector and it was just a piece of plastic did a beep test and the adapter is good as long as the right pins are soldered. I will open up the brain and beep test the ODB2 connector to device as well as ODB1 to device. Damn BMW.
The error I get when scanning with B800 is 38/02. Looks like it is "Warn Lamp" as per the booklet. What is it and why am I unable to clear the code?
Give me a chance to research that one. Ill try to get you an answer.
Bartosz- here are two old threads about this same problem- zroadster.org/threads/fault-codes.464/ and www.bimmerforums.com/forum/showthread.php?2405358-Airbag-light-issue There is a LOT of information in both of these- one that I found interesting in the second thread is the possibility that the manual is wrong (it does warn about that on every page), and you actually have a table 40 fault 2, firing circuit belt tensioner drivers side. I can't diagnose from here of course, and I'm not sure where you are, but if you can get access to a more comprehensive code reader, that might be the way to go. Let me know what happens.
@@MomentofZed Thank you very much for your help! Im in the UK/Poland. I am working on getting laptop with windows xp, rs232 port and proper interface so I could use INPA poperly... Current USB interface and INPA installed on windows 11 don't work with airbag module at all...
@@bartoszuczak5730 hope I helped! This light has always been an issue on these cars
Dumb question, but is it definitively safe that using this reset tool, to reset, still renders the airbag operational should it be necessary? I mean, DEFINITIVELY?
Not I nor the device make that guarantee. With that said, the problem is not necessarily an airbag. There are other parts in the car that make up the SRS system and will give the light.
Thank you @@MomentofZed for replying so promptly. I am worried about that light especially when buying a used Z3 and that light is on. Seller bought it being on. Car is in good shape though. What would you do?
@user-be1gy5kj9x if that is your only issue, I'd buy it. If worried, hook up a full boat scantool to the under hood connection and get the details.
well this did not work for me. the light is still on. but i had different codes then you so maybe that is why?
Possible. Did it go out and come back on? Or never went out?
@@MomentofZed never went out
Should I trade a 2002 Yukon with 150,000 miles for a 1999 z3 with 62,000? 5 speed excellent condition. Just wondering if anyone thinks it's a fair trade $ wise. I know the cool factor and rarity are selling points.
I'd check the bluebook on both first. It sounds like good deal, but I'm biased! Plus, do you need to haul stuff or haul a__? 😀
I just worked a cash deal on the car. I'm gonna pay $4,000.
@@humblehuman831 if it is in good shape, you stole it! Congrats!
I just bought a 1998 Z-3 for $10,000.00. $12,325.00 it had 39,550 miles on it. Did a I pay too much?
I think that is ok. What motor? Stick or auto?
@@MomentofZed Hi: I’d only buy a standard transmission. I walked out the door at $12,355.00. It included a repair on the passenger door and the piece that holds the seat belt in place. They never fixed that. Do you have a video on how to replace the seat belt holder? If so please let me know when you can show it. My Z-3 is forest green. I’m not sure if the motor for the hood is working???
@@domenickvellone5207 i have a video about that part. In the description there are links to folks who have done it. It involves removing the leather.
