location of the tpms (rdc) module
 

Hey everyone, I've done a good interweb search with no luck? 2012 35is, anyone know where this part is? Looking to potentially unplug and decode TPMS light.

Thanks in advance!

Sorry not pertinent but what the hell is a 35is?

Sorry, typo. Thanks.

Hey guys...so maybe I'm slow here, but I pulled apart the lower dash looking for this thing and couldn't find anything close. I found the ICS and the LCM, but no RDC...this is the part I need to unplug (attached pic, part #1)--but I don't know where it is on the car??? Anybody know where the antenna is to unplug? Thanks!

Just a guess, but check on the back side of the fender liner in the wheel wells. This is where it is on our 2008 328i.

Can I ask what your issue is, and what can be done by the decoding you intend to do? How do you decode?

I ask because my TPMS is giving a malfunction warning daily, I believe one or more batteries in my wheel mounted sensors are dying. The warning will appear for 5 secs and then go away.
I am actually bringing it into the dealer tomorrow so not sure I will see your reply before then...

Thanks! I'll check later tonight. My Indy even said it was underneath the steering wheel behind the vent tube. I removed that and nothing there...

I upgraded the wheels to style 128's and the TPMS sensors aren't the same frequency--so instead of removing the tires and putting on new sensors, I just went the coding route.

Not sure what my coding dude did--he's the one I use to turn off seatbelt warnings, use the key fob to close the trunk lid, etc. He coded the warning light off, but the RDC needs to be unplugged in order to make the light go away.

Hey just a heads up, I may be talking out of my azz. I found this thread and apparently those boxes on the fender liners are 'triggers' not antennae?? I have no idea what a trigger is or why it is needed. Or why these systems need to be so complex.

Position of RDC antenna

E70 is using the new type RDC system where there is only 1 antenna integrated in the control module which is located underneath the floor. Pretty sure unplugging he module will not make the warnings go away if the coding(decoding?) has not been done correctly.

Awesome, thanks for the reply... Any chance of being more specific than under the floor?

I didnt have time to look in ISTA tonight, but it must be somewhere around the rear subframe.

Ok, thanks... I'll dig around some more!

Follow-up to my post above:
I went two days after my appt where they replaced the TPMS Module, and the second day I did get another TPMS Malfunction message. So, the new module did not solve it. Back to the dealer...

My TPMS continues to randomly and sporadically give TPMS MALFUNCTION WARNING .
This can happen once a week or 20 times in a row on a long trip - very annoying.

Dealer says its not the sensors in wheels getting low on battery, that would give show a error code in the log, I have none. They replaced the "TPMS" module last year, no effect. I had them look at it again over xmas and they could not (did not take the time to) solve it.

Getting pissed off, is there any easier way to turn off this malfunction warning?
My only other options are to pay for them to find the (presumed) loose wire, or code the system to ignore (sounds like OP went this way).

Anyone know the location of the TPMS controller/Antenna in a 2011 X5? This seems to be post 10/10 build, so newer style. I pulled the plastic cover/trim under the driver and couldn't find it. Mine is throwing TPMS Malfunction and reset is not available.

Good luck, would love to find more info too.

I watched a youtube video where the guy opened up the sealed plastic box on the Antenna/controller and there was water corrosion inside on the little circuit board. If I could find it, I'd like to see if mine is like that. I also found there is a newer part number. Maybe better sealed?

If you find it let us know where pls?

+1, have the TMPS Ext Interference error on a sporadic basis and would love to find that and find a solution.

Is there an easy way to disable the TPMS system in the meanwhile, to avoid getting the intermittent "Malfunction" message? Like pull a fuse or something? This gets really old on long trips.

Found it. Poking around under the car and located it in the rear of the vehicle between the muffler and the differential. Unhooked it and tried car. Same tpms malfunction. Opened the sealed box. Found corrosion present on the circuit board. Seems there is a vent that lets moisture in. Cleaned up the circuit board with alcohol and a toothbrush. Still same fault. Took it for a drive, all other faults cleared but still tpms malfunction.

OK I found it too. Its a little bigger than a bic lighter.
Its easy to see in its bracket on the frame, and labeled "REIFENDRUCK - KONTROLLE". The wiring merges with a larger harness and then to the back of the passenger rear wheel well.

I did same test as you, unplugged it and started car, got the "TPMS Malfunction Warning" and gong, flashing dash light and iDrive error message.
The plug connections looked clean but sprayed them out with WD40 and blew them dry, re-installed, started car, no error. Drove around for 20 mins and got the error 3 times. So no change.

So either this second replacement TPMS module is defective like the first (unlikely) or I have a loose wire that intermittently breaks the connection.
Do they have a diagnosing method to trace that issue if its in the wiring or CAN-BUS? This sounds difficult (expensive) when the issue is intermittent. It only seems to stay disconnected and issue the warning for ~10 secs at a time.

PLAN A - unplug and tape up the connections, and drive around to see if the gong and flashing light on the dash subside after a minute. If YES, this is how I will drive the car on some upcoming long trips. That gong and flashing light drive me nuts. One solid dash light on, I can deal with.
I will do this tonight/tomorrow to confirm.

PLAN B - Will need new tires soon, and its time to change the wheel sensors too. I guess I can HOPE there is a chance that with new wheel sensors the issue is magically resolved, but I am not holding my breath. Dealer states that would leave error codes that they did not see.

Anyone know what code / error message would be shown if the module was intermittently losing connection to one or more wheel sensors? Same as above or different?

PLAN A - Confirmed.
The module is sitting on my bench in the garage, and at each start I get the gong/flashing warning light for TMPS Malf. After a minute those stop and I am left with a solid TPMS light on the dash, fine. Looking for a little sticker to put over that for my upcoming long trips.

I'll still try PLAN B when I get tires.

This will have to suffice until I take the vehicle in for one of the outstanding recalls, at which time I will ask that they hunt it down.
I was warned last time, that wiring issues would not be covered under the CPO warrenty, and having them track down a loose wire might be costly.

GOOD NEWS
The TPMS MALFUNCTION error that has been plaguing me has been Vanquished!
4 new TPMS sensors in the wheels seems to have solved it. 2 weeks and 2k miles since my tire service and No Errors!

Seems the dealer was wrong - no faults were registered from any sensors, as they said would be the case. Occam's Razor - the simplest explanation is most likely the correct one.

Anyone have a picture of this sensor location? I've tried crawling under there but didn't see it. Is it behind a shield or something? Have replacement, but need to know where to put it. :D

From new TIS website...there appears to be two types (one is named "low cost")...once you go to the page...click on the one you need:

https://www.newtis.info/tisv2/a/en/e...control+module

Wait, the one I discussed above in my posts is not the same one as in those links.
Mine was on the front side of a frame rail running left to right between the diff and the muffler. Very easy to spot, labeled as I wrote in an above post.
I don't know which component 740is is looking for. And I can't speak to what the components are that Qsilver posted; those appear to be under the hood (I didn't recognize those location diagrams).
I *think* mine is an antennae and the others are actual RDC modules. But I am not sure by any means.

The link that Q posted has a link to the "Low Cost" sensor and that is the antenna that is between the muffler and the differential, part number 36236771043. I'll be going under this afternoon to hopefully find and replace it. New wheel sensors didn't fix it for me.

Thanks Q for the link. I'll try to take a pic of it too when I find it.

:thumbup:

Didn't get a chance to replace this yet, but will get to it this weekend. :D

Ok, yep, that is the same part I referenced. Those illustrations are ok unless you don't know what part of the vehicle they represent.
Do let us know how it goes.

BTW, 740 did you check on that braided interference cable I mentioned to you?

Not yet, was so busy looking for the sensor, I forgot to look for the cable you mentioned. You happen to have a part number and/or pic?

2007 e70 rdc location?!?!
 

I give up. I have searched all over under my 2007 e70 4.8i CCC. I cannot find the rdc module anywhere near the rear axle or muffler. Can someone take a photo of its location?

740iS - I think it's 12427568573 interference suppression strap. Mine (2012) is blatantly obvious sticking your head under the driver side right behind the rear wheel. Runs from muffler attach point to frame 12" away.
However with all the confusion above I am wondering if there might be more differences between the original and LCI iterations than we assume.

Same answer to BigBilly - on my 2012, if you slide under too near the rear diff and have a good look, there is a frame rail running L-R between muffler and diff. On the front side of this rail just driver side of center, this little unit is clipped. The wiring enters it from the end towards the rear wheel. Its a little bigger than a Bic lighter. It is labeled in German "REIFENDRUCK - KONTROLLE". There aren't many other electronics visible from this location and I saw it immediately. Which is why I am wondering if there are more differences between the early e70 and the LCIs.

Looked it up, yes that's the part number. Need to verify if the 08 has the strap or not. Realoem.com shows that it does exist on my '08, but I'll check for sure and see if it is rusted out or not. Since my X has always been a CA car, I'll be surprised if it is rusted out, but now out of the question.

Check this thread regarding the strap, sounds like there may be more than just the one on the exhaust :
Exhaust ground wire - Bimmerfest - BMW Forums

Mine was def not rusted, it looked torn off or cut as mentioned in that link. Btw I looked and it's not a foot long, only several inches.

For you and Big Billy, I snapped a couple pics under my X5. One of the strap, one of the module bring discussed.
Well I am unable to re-size them on my phone, so will do so on my pc later and upload here.

Found the strap this morning, but not the sensor. Strap appears fine and there are mounting points on both ends of the muffler, but only one strap.

Couldn't find that darned sensor though. Even removed the heat shield above the exhaust pipes right above where they enter the muffler and still couldn't find the darned thing. Looking forward to your pics.

Ok, good on the strap. Here are pics of both, taken from laying underneath behind the driver's side rear wheel. (You don't even have to be fully under to see the strap in the second shot.)

TPMS Sensor, on the forward facing side of this frame rail, behind diff and in front of muffler:

On my 2011 x5 35d lci built 9/10, theres bolts but no module on that frame rail in heatmizr photo

It might be here instead

That previous link was for receiver... So low cost seems to be the new system past 10/10 mfr date, the one by the muffler.

But our pre 10/10 control unit is under driver wheel.. It's bigger than the low cost one
https://www.newtis.info/tisv2/a/en/e...s-rims/P0UXnh4

If you want to get rid of TPMS and switch to FTM which uses wheel speed sensors, here's what I did today:

I just got it working. Now it says FLAT TIRE MONITOR in CIC!

On pre 10/10 build date e70, unplug the RDC module which is under the drivers dash:
Follow these directions to get to it... when you unplug and remove it, it will say RDC on it.
https://www.newtis.info/tisv2/a/en/e...s-rims/P0UXnh4

On 10/10 and newer build date e70, unplug the RDC module which is located on a frame rail near the muffler:
See this link for photos: https://xoutpost.com/1121861-post40.html
Or you can see in newtis: https://www.newtis.info/tisv2/a/en/e...-rims/FCVcPPJi


Remove VO $2VB from CAS and FRM (not sure if necessary but did it anyway).

Things to change in coding modules:

Quote:
CIC
--------
RPA_CIC aktiv
RDC nicht_aktiv
RDC_SAFETY nicht_aktiv (already off on e70 but check anyway)

(For non CIC)
CCC
RDC_CCC nicht_aktiv

MASK and Champ
RDC nicht_aktiv


EHB (DSC)
-------
AUSSTATTUNG_RPA aktiv

KOMBI
-------
RDC_VERBAUT nicht_aktiv
RDC_APPL_MONITOR nicht_aktiv

After you do your typical key out, wait a bit, key in start engine.
Go into idrive and see the Flat Tire Monitor, you can reset there.

That's it!

Your pre 10/10 TIS link is not valid. Can you confirm complete URL?

Question, do you think this coding could be done in Carly?

Link fixed. No, Carly doesn't have all of the options that NCS offers. Carly is a canned coding approach- much easier to do specific functions but it doesn't give you direct ways to change individual parameters.
Added CCC and mask/champ coding for the flag !DIRECT_RDC (how I found the ones for e70 using that flag)

Wow, now this thread is getting interesting!

Ok. Thanks for all the work. Looked around again today, and definitely not back by the muffler. I'll dig under the drivers wheel this evening, if I get the chance.

Tpms antenna location for pre 10/10 build date e70
 

The tpms antenna is right under the driver on pre 10/10 e70's. Remove the panel from under the car and you'll see it right there. Hope that helps somebody!

TPM RDC repair
 

If you're reading this thread for the RDC location perhaps this video will help you fix it ... once you find it and remove it.

I disabled my TPMS as well. Mines was definitely the white box under the steering column area. Very easy. Mines an 02/2009 3.0si.

Sorry to revive an old thread. I sent heatmizr a private message but I am wondering what the exhaust ground strap has to do with this? I was planning on replacing the module. I have a new ground strap too because I noticed it was broken.

Hey Steve, got your message. I had to re-read the thread to recall how it all went...
When I kept getting that error message, my dealer had replaced my small module I posted a pic of (rear frame rail ahead of muffler) to no avail. Later, I had all new sensors put in all wheels, which PRESUMABLY fixed it.

The reason I say PRESUMABLY is that I had this grounding / interference strap on the muffler replaced at the same time as the 4 new sensors in the wheels... So I cannot prove it was the new sensors that fixed the issue because of this variable. So when 740is posted a separate thread looking for the cause of his issue, I sent him info on this strap as a possibility to look into, as I thought it was possible that when broken it might be causing some issue with my TPMS signals.

Again, I assume it was just replacing my 4 wheel sensors that did the trick, but...
[One note - I didn't notice any radio (or other) interference before the strap was replaced, or any improvement to anything afterward... so who knows what it really does.]

Thank you! I appreciate you being there to answer this question.
I have a new strap to throw on there, 4 new sensors and a new module coming.
I hate warning lights!

My pleasure!
Say, one nice little bonus would be for you to prove that the strap does Not impact this issue. You could do this by installing all your other components and seeing if the light goes out, before installing the strap.
Let us know!

On my '08 I replaced all of the sensors in the wheels the "antenna" under the drivers side and the "receivers" in all four wheel wells. The only thing I didn't replace was the control module under the dash. But I continued to have the errors occur. Ended up getting my 2013 and selling my 2008. So I can't say what the final repair would have been.

Converting the system via programming as was discussed earlier in this thread, would have been my next step had I kept the vehicle.

Will do!

Ok... well I installed the new RDC. The ground strap didn't do anything TPMS related. I bought a new RDC from BMW. As expected, I still get "TPMS MALFUNCTION" because I haven't coded it. I have an NT510 so I am limited there. I thought I would check the fuse, because the inside of the RDC was quite corroded and I just wanted to make sure it's not shorted out. I am having a hard time finding the fuse. All my resources say to look for fuse 7 but I don't have a fuse there. Is that for the more advanced system?
