Hello! Welcome to justanswer!

 

ITs behind the glove box for the front passenger. You have to take out the glove box. Do you want the procedures?

Are you sure? The SA at BMW said that it is located in the trunk area behind a panel. So I guess the SA is wrong. Which module is behind the panel in the trunk? Yes, please send me the procedures for removing the dash to replace the RDC module. I also need to know how to reprogram the car to accomodate the new module
Ok, what scan tool do you have available to you?
Ask Your Own BMW Question
Customer reply replied 6 years ago
EDIABAS OBD2

Ok, what software are you running on that connection?

Ask Your Own BMW Question
Customer reply replied 6 years ago
INPA4 ... but it does not say on the CD that came with the Ediabas/INPA4 interface.
Customer reply replied 6 years ago
Please verify location of the RDC module, and provide instructions for removing the dash to replace this module.

Sorry for the delay....

 

In the files below are all the procedures. As for coding the module to see your sensors, I'm not sure of the software you are running and if its possible that way....

Okay, part of this replacement of the RDC requires disconnecting the battery. How is this done?

 

Does this car have one or two RDC (TPMS) modules? If two, then location of the 2nd module?

It has one module and two antennas in the front and rear bumpers. Those should be ok.

 

As for the battery, just unhook the negative terminal which is closest to the rear tail light.

Isn't there an on-off battery "switch" located above the fuse panel in the rear hatch area? If so, can I simply hit that switch while I do the part replacement? Any idea where I can find a used RDC module?

No switch or I would have told you. Unhook the battery. As for the Used module, try

I just checked above my fuse panel and there is an on/off switch. If this is not for the battery, then what is it for?

Its not a total battery disconnect. You must unhook the battery or the air bags will remain live. This is the only way. The battery is in the trunk under a cover passengers side.

Okay, at page 186 of the BMW handbook this switch is called "battery switch," which reduces current flow when the engine is off. So disconnecting the negative terminal must be done prior to removing the RDC module.
Right. But its not for just the RDC, its because you are working with the Airbags also.

Have you replaced an RDC module? Will I get error codes or need to reprogram the car after replacing the RDC module?

The RDC needs to be coded and the sensors in your wheels taught to it. I don't know what software you have nor how to do it with your software.

Will it work okay without having a TPMS sensor in the spare tire?

No, it will warn you of that on the dash and show all tires as being low.

Ask Your Own BMW Question
Customer reply replied 6 years ago
Okay, in what position must the spare tire's TPMS sensor be pointed? That is, if we are looking at the hands of a clock, at what number should the sensor be pointed toward, when positioning the spare tire in the storage compartment? 10, 11, 12, 1, 2?
It does not matter. The sensor has a pretty far range. Ive seen them work 10 feet away from the car.
Ask Your Own BMW Question
Customer reply replied 6 years ago
That's good news. I've read that it must be angled toward an antenna. How do you check the sensors to make sure the batteries are working?

I've heard that too. 9 or 3 o'clock is the shortest to either antenna. As for as batteries, the scan tool can call up the remaining battery life but what I see is after about 5 years, they are done or very weak. New ones are available in the link below:

Speaking of the battery, if it's low on charge but still starts the car no problem, could it be affecting operation of the RDC module? There is a display that says "recharge battery." Does this mean to recharge the car battery? If so, can this be done with a trickle type battery charger connected to the pos/neg terminals in the engine compartment?
The message you have now is for the main battery. Yes, you can trickle it from the lug under the hood. I prefer to hook right to the battery though. Its never a good idea to test anything in that car thats computerized if you have a low battery.

How long should it remain on the charger?
How many amps does your charger put out??
Ask Your Own BMW Question
Customer reply replied 6 years ago
Two settings on the Dual Rate Battery Charger: 12v 2 Amp and 12v 6 Amp
Run the 2 amp setting for 24 hours. Do not use the 6 amp as its too high for your battery type.
Ask Your Own BMW Question
Customer reply replied 6 years ago
Okay, the other charger is not rated in amps but simply "Output: 13.5 Volts DC." How long to charge with this charger?

Use the 2 amp charger. The 13.5 constant wont fully charge the battery.
