OEM TPMS Retrofit- The full package doityourself

[mauro23]

Hello guys,

i know, it is a long time now but i am still trying to fix the issue i have to reset my RPA (TPMS) system.
So, after my last post, i went to a lot of forum searching about information for that retrofit, to understand why it is working for some persons and not for others having the same DSC MK60 module.
There is what i found :
it will only work if you have a ZHP E46. Even if you have the same DSC MK60 module, activate it through NCSExper and cable the wire, a "normal" E46 won't have the possibility to reset the RPA system if the light goes red. The reason seems to come from the factory software programmed in the DSC module which doesn't read the button status for a "normal' E46 and does for a ZHP even if you don't have the RPA system in your option list from the beginning.
So hopefully, i found a way to reset it through INPA, and it works well.

Right now, i am trying to see if there is a way for me to flash my DSC module through winkfp with the same software as the "normal" E46 having the option from factory. i haven't found somebody who tried it yet. So if somebody here have an idea, let me know. Otherwise, i will let you know as soon as i found something.
@jupiterBMW, i think you should add in your first post that for the moment, this will only work if you have a ZHP version.

Sorry to dig up an old post, but I have a couple of questions. What type of wire are most people using from the button to the DSC? Also, half of the pictures in the original post are now missing. Does anyone have a copy of these laying around anywhere?

Hello, best wishes for 2016 first of all and sorry for the late answer.

Basically, i used a 0.5mm² wire for this button (i guess it is 50gauge, is that possible ?) It is anyway a pretty thinny wire. You can use the WDS website to determine that. On every schema, you can see the type of wire you need to use at least.
Good luck.

Hi there... As for the wire needed, any sort of generic multi-strand copper wire of approx 16-20 gauge will work just fine. The wire I used was a spool purchased from Radio Shack.

To the post above, 0.5mm2 is NOT 50 gauge... I don't believe there is anything as small as 50 gauge... To give you an idea, typical Cat 6 cable (ethernet cable) has 8 strands. Each strand is 24 gauge, 23 gauge for heavier duty stuff.

Sounds good, thanks for the response. I used a section of speaker wire which is a solid copper core ~18 gauge. I completed the coding from the first post here "Description~String~Options (Default)
1. Tire Pressure Control System (RDKS)~RDKS~aktiv / (nicht_aktiv)
2. Can-Bus Tire Pressure Control (RDC)~CAN_RDC~aktiv / (nicht_aktiv)
3. Tire Pressure Control System (RDKS) Warning Gong~AKUSTIK_RDKS~aktiv / (nicht_aktiv)
4. Output Device for tire pressure control system (rdks) warning~WARN_MEDIUM_RDKS~gong / (piezo)

Once this is done, you'll need to code one line in the MK60 module. The line is below.

Description~String~Options (Default)
1. Tire Pressure Control System (RDKS)~REIFENDRUCKWARNSYSTEM~aktiv / (nicht_aktiv)"

Now upon start-up, I get the yellow and amber tire pressure icon on the dash, but nothing happens when I press the tire pressure reset button. The wire seemed to plug into the terminals perfectly, so I am wondering if there is something else that I need to code. I have seen somewhere else that I need to add $251 to the vehicle order. Can anyone confirm?

Look back in my original post, you might need to add to the vehicle order, but I can't recall.

Also, pressing the button shouldn't really do anything. The best test is to go drive the car, lower a tire pressure about 10psi, then drive some more. Within a mile at the most, the light should turn on. Refill the tire and then hold the button down to reset

So I did this and it never set the sensor off. I was under the impression that pressing the button should give you a signal on the dash that the system reset even if you don't have a warning light.

Damn I don't remember. Do a search, I know I found the info when I did it, I didn't figure it out on my own that's for sure.

Ok, looked again... Did some searching, and yes, you do need to add $251 to your VO. Once you do that, you will need to update your modules and activate the lines that I mentioned in the original post...

Good luck.
