the gong sound (need help please)
 

I need help. I think my gong is malfunctioning. It works when things are low or a fault is triggered like (low oil, check brake, etc) It does not work for memo or speed limit alert. I put a scanner on the X today and the mid had 2 errors even after I cleared it. Gong T1 and Gong T2. (pa soft 1.40.9) From my research the gong is one speaker possibly 80 ohms.

It still works for the T3 tones and frequencies so how do I troubleshoot it? I have verified T1, T1 and T2, dont work. I have not verified if T2 works as it has not been that cold.
----
from wds site
The hour signal T1 reminds the user of radio news broadcasts or traffic announcements with three short "beeps" (1 kHz).

In the case of the temperature warning T2, one single gong (1 kHz) is triggered which warns the driver of low outside temperatures (ice hazard).

The short code signal is triggered by the tone T1 and T2 (750 Hz). It indicates to the user that the programmed speed limit has been exceeded or it draws attention to a code function still active when starting.

Warning signal T3 warns the user by means of a long tone (1 kHz), followed by the gong sounding. It acts as the acoustic signal for the light check module (LCM

These acoustic functions cannot be triggered by the instrument cluster electronics (IKE ) but rather they are a functional part of other vehicle components

Anybody got any guidance?:dunno:

Update.. the problem may be worse than I thought. I removed the gong applied 12 volts + and negative and triggered t1, t2, t3, t4, and t5. No sound from t5 but I'm not worried about t4, and t5 as I dont have PDC. But now I'm nervous its another electrical issue as the gong is fine for t1, t2 and t3. Somewhere its not getting the correct voltage or something. Studying the schematics on WDS site now. again if anybody knows anything please assist.
Also test 13 on the obc only does 1 gong not all 3.

issue resolved...
close this post

how ????:dunno:

In case the OP doesn't respond...what is your issue?

Have you tested your GONG to see if it can replicate the tones? You don't have any model/model year/build date info...so we can't tell if you have the high or low cluster...but if you've unlocked your cluster...you can do TEST 13 to check the GONG:

Yes hello and thanks , glad someone is here , my x5 is 2003 late , e53 , not sure if low or high cluster , when I do test 13 it shows gong and question mark but nothing to hear ! Not at all , read out says frond acoustic generator at fault , replaced all sensors to no avail ! Thanks christian

If you have the "high" cluster...you have a 20 digit alpha/numeric display in the cluster where all the check control warning messages appear...and the display looks just like the one in the video where GONG? appears. There's also two buttons on the display...one on the left side and one on the right side.

The "low" cluster only has one button (on the left side) and uses a graphic display to show the check control warning messages...thus there's no display for strings of text (words) to appear. And to unlock the cluster and access the OBC TESTS is slightly different. :)

When discussing or asking questions about the instrument cluster...it helps to identify which one you have so that your responses, answers, suggestions, recommendations, etc...are based correctly on what you have.

thank you , now i have tow wait another 24 hours , haha , honestly i am grateful for your reply , ok now we established that i have the high cluster , it is the non sounding gong that brought me here , if i go to test 13 the gong shall be heard and tested but i hear nothing and that is where it all stops , any help making it sound is also highly appreciated , thank you so much , Christian :popcorn:

Which sensors did you replace? The "accoustic generator" is the gong/chime itself...did you replace that?

Item #2 in the diagram below is the "gong"...is this what you replaced?

i am sorry i was inconclusive again , i will work on it to save you time ! i have exchanged all perking sensors , all click and on read out with obd code reader it says front acoustic generator off , which then brought me to : have a look if the gong is turned off , not to make a noise so to speak , i have then entered ( unlocked my obc ) and have run test 13 with no gong/chime to hear , that is where i am , so i am guessing i need to locate the gong thing and take it out and run 12 v trough it , is that right ? would you know where i find it , considering i am german but i live in the uk and my car is a uk model hence the steering wheel is on the wrong side , and mybe the position of the chime thing is not known to you , ok so that is all i can say , grateful for your help , christian

The gong on a LHD e53 X5 is located below the dash (underside pointing toward floor) between the dead pedal and brake. Not sure if its in the same place on a RHD...or if they move it over to the other side.

Either way...look for it below the dash on both sides...you should see the surface of the grid (lots of little holes like in the diagram)...the rest of the gong is hidden from view.

thank you very much !

still dispair .....
 

hi let me thank you , you are the only one replying here really so i am grateful , i found out today that apparantly my gong is in my instrument cluster , i did s a soft reset , meaning , took all plugs out waited 5 min and reconnected it , no changes my gong is still making no ! noise , havent opened cluster just yet ! do you have any other info relating the gong location or how to activate or why the gong has a question mark next to it when i do test 13 , hope i dont bother you to much , thanks christian

Not sure where you got info about the gong being in your cluster...but that sounds like info that would apply to the new generation BMWs that came AFTER the e53 that have iDrive (like the e60/e65+/e70/e90/f01/f10/f08/etc)...which also uses a totally different communication bus system for sending data to various modules (MOST & LIN bus to name a few).

When you pull up TEST 13 on your instrument cluster and you see "GONG?" in the display...did you press the LEFT instrument cluster button to initiate the TEST?

BTW, do you also have PDC (park distance control) which also utilizes the front gong...and there's a rear speaker located somewhere in the rear, too (if you have rear sensors.

great thanks , i called the main dealer for bmw in the uk , gave them my vin number or reg number and that is what he told me , in the ike , yes the beeper in the back is working and sounds the long beep indicative for male function of pdc , yes i ran test 13 and gong ? came on and i pressed left then gong without ? but no sound at all , again read out says front acoustic generater off, all sensors ticking , pdc switch blinking green fast , still dont know where the flippin thing really hides , i am trawling googles picture pages in en mass , its nuts !

Christian, I got your PM, hard to decipher it, so I am replying here...

Let me try to understand what you are trying to accomplish:

you have PDC (parking distance control) and want to hear the parking sound when you are approaching an obstacle, right?

you mentioned, that the PDC green light in the center console module is fast blinking - this is an indication of a PDC malfunction

You mentioned that the front acoustic generator is off, and when you test the gong in TEST 13, you get no sound at all... It also should be evident, that you do not hear any gong when the key is left in ignition with engine off and drivers door open, or a seat belt is not buckled.

The simplest solution is to go into the floor area in the front (you have RHD car, so it might be different, just as Q7 said before), and look up, at the "ceiling" of the footwell. On the LHD cars, there is a small area that has plastic slits in the cover, and that is where the "speaker" is hiding. You will need to remove several screws that hold the plastic cover, and the speaker is snapped into plastic holder. The speaker will have several wires going into it, check to see if those wires are all connected, if any are cut, or otherwise disconnected - some people resolve the annoying issue of seat belt chime by cutting off the wires to the gong speaker.

If the wires are all present, then you need to see if the gong speaker itself is malfunctioning/damaged. Try to get a spare gong from a wrecker/junk yard, as a brand new one might be too expensive.

If the replacement speaker is not working, then we need to troubleshoot further - but first, accomplish the steps that i mentioned.

I am going to look up the WDS diagrams to see if the gong is on the left side of the car (a la LHD) or on the right side of the car (as if in RHD)

here is location on RHD

ok great , thank you very much for your time ! both of you !

the problem starts here , there is no gong in the foot well, i have thoroughly checked drivers and co drivers foot well , i am happy to take pictures of it .

which is why i called bmw and gave them my vin number and got told it would be in the cluster ( ike ), it isnt either !

so i have pdc , all sensors are replaced , and ticking ,get a loud long beep from the back , malfuntion sound , the blinking of the switch , and no gong for whats so ever , i can leave all 5 doors open and its not chiming , so condensed there are two options , either a former owner might have taken it out or i dont know the location , i have access to autodata - i can not find anything but a part number / picture .

this is all i know , i am sorry - but i wont give up ! thank you for your time guys

thanks
 

BTW, do you also have PDC (park distance control) which also utilizes the front gong...and there's a rear speaker located somewhere in the rear, too (if you have rear sensors.[/QUOTE]



but this is wat this is all about , the pdc , not having a sound /gong / chime renders my pdc useless .

i dont care so much of the sounds of temp and door open or speed warning etc this is all under control by me being observant

Since you can't find speaker in that location it means someone took it out. Find connector X363 inside footwell and buy replacement speaker

TX5...thanks for finding a picture for the gong's location on a RHD X5 (H10 in the pic). It looks to be just like the LHD except the mirror opposite location...but still below the dash & above the accelerator attached to a panel with the sound directed towards the floor. It appears to be close to the door or wall of the footwell.

more confusing news
 

latest newest info i received from ocean Plymouth uk - bmw dealer , is that the gong thing apparently is in the nearside inner arch , i will find out , also i can not see cables or a place where it could have been in the foot well

yes thanks tx5 , amazing job , i could not find good one like so , bad news is i havent got that , i have taken everything in both foot wells out , i do tho have conformation that my car has a gong , or had a gong , fitted from start , also i got told by a senior technician today that the gong might be in the wheel arch near side behind the lining . i will update you on this , thanks again christian

Christian, there are several items in an E53 that can make a sound - a gong that we are talking about, a speaker for the rear PDC, located behind a trim panel in the trunk, where the rear fuse bank is at, a siren that can be hidden behind the archwell (i don't remember on the E53, is it located in the wheelwell?), of course music speakers, from 6 to 10 or even 12 speakers...

The gong tht we are talking about is located where that picture depicts it - there were not variations in the life of the E53, except for LHD and RHD... If you could not find it, probably because it is absent as it may have been physically removed. Take pictures of the covers in the footwells for use to see, please...

thank you , i will take pictures by tomorrow , its 9.21 pm here now , i do appreciate your help , all other things in my car make the noise they are supposed to , its the bloody gong thing , since my car is rather mute , meaning i don't get outside temp alert or hour beep or belt gong or door open gong and - i don't want those , all i want is my pdc to work and it seems to work , or all other items seem to work besides the front acoustic generator , the gong apparently ! the one i don't seem to find , but pictures tomorrow ! thank you guys

On the e53...the alarm siren isn't in the rear right wheel well like on the sedans (e38/e39 specifically). On the e53...the DWA alarm siren is located in the cowl area of the engine bay:

well i am all about the gong and i am sorry we cant make it easy i failed putting up pictures ,

can you work with these ? c

I'm lost...don't know what to tell you...but below is the gong (BMW part # 65 81 8 360 995 now replaced with new part # 65 81 9 155 105):

QSILVER7 thanks , i really appreciate all your help , i do know how the gong looks or should look like , i cant see such a thing, hence i took these pics for terminator or you to maybe point out where it should have been or could be hidden , the thing none of the technicans in bmw garages in the south of england have a flippin clue where it could be , wonder if i ever will hear my pdc or a chime .........

Is the 3 pol plug in the pic above normally attached to anything when everything is put back together? If not, it looks like it would be the 3 pol plug that fits 3 pol socket (just above the 11 digit BMW part # 65 81 8 360 995) in the gong that you're missing. (see pic below)


http://i.ebayimg.com/00/s/MTIwMFgxNj...mh!~~60_57.JPG

i see what you are saying , the three pol plug is just there , i didnt do anything to it , so i guess i will buy a gong , plug it in and watch my ears ? i will let you know , thank for pointing it out ! may the x be with you

:) Good luck...I wish you success. This has been an amazing thread...approx 1600+ views as of this post...but only 3 people active in it. Ahhh...there's that silent majority again. I wonder if any RHD silent majority members were reading this thread? :D

thank you and as promisid i will inform you ! i normally dont do minority stuff : )
