Vehicle Settings apk does not work correctly

I apologize: Sorry.
I had not even seen the TPMS Category:Sys Interconnect.
Unfortunately it does not work.

surfer63 Unfortunately it does not work.

Potentially stupid question: Many VW/Skoda etc have a passive TPMS that works via the ABS sensors. These don't have TPMS sensors in the tires, as active TPMS systems would. Yours is active, yes?

To be honest: I don't know. I do know the difference, but I do not know what I have.
A passive system on the ABS/wheel system should only warn in case your tyre is losing air fast.
But my front-left tyre had a slowely leaking valve slighlty over a year ago. In about 1½ month I got a warning that it was below 2.0 Bar, so I simply inflated it again. (I have a small generator which I use regularly to inflate/deflate my car and caravan tyres). Then again after _1½ month, and again after _1½ month. That's when I went to the garage and had the tyre checked (OK) and then the valve replaced.
So it looks like an active system, but the garage told me I had the passive system.

I have the RZC (Raise) box, set to Volkswagen, Octavia, 2015-2019.
The direction is displayed in the MFD**, but I have no idea whether it is visible somewhere in Dudu. I will check tomorrow.

** I did not even know what an MFD was 😉

Ok the passive system doesn't show pressures, only the active one does. On the active one, you typically go to the TPMS menu in MFD and "store pressure" after airing up (effectively you tell the system that all tires should have the correct diameter now and then on the next couple of Kms it learns the rotation speeds and later triggers a warning, should a tire deviate, works also for slow leakage). That storing is not needed on the active system, as it measures pressure directly.

PS Thx for confirming the compass. I figured out why it's missing here: The car thinks DUDU is just a radio - will change that to become a Navi also.

This should have read "On the passive one..." though, but I see you still understood correctly 😉

Yes, I now use that option.
But unfortunately it still doesn't work.
I also mentioned that that function never worked, not on my previous units either.

@gismo explained why it will never work. The VAG passive system will only send warnings (via CANbus) when pressure is too low. It will not (never) send pressure values as such.

I will also change the English and Dutch translation of the current "Three-Party's TPMS".
It should be "Third Parties TPMS" or "3rd Parties TPMS". Likewise for Dutch (TPMS van derden).

We are currently coordinating door switches, tire pressure, and air conditioning data for multiple brands of vehicles
You can update the new DUDU Base application to be released one month later and then check if there is any data on tire pressure
If there is still no tire pressure data, it may be necessary to check whether the wiring of the vehicle and DUDU equipment is correct.

Hi, thanks for the reply.
But it is as @gismo says: The VAG cars with a passive TPMS system do not give data back to the car. They can't give data in any way to dudu. Knowing this fact made it also easier for me to google on this, and it is correct.
The only "message" they give via CANbus is if one of the tyres is suddenly having a lower pressure. So they do not give tyre pressures or temperatures. They really only give a warning message that one (or more) or the tyres is suddenly loosing pressure.
I really think it might help a lot of other users, but not the users with a VAG car with passive TPMS.
I will add the new base application though and see if it gives some more info in other areas as still data is missing from the car info screen.

What is Dudu Base application?

surfer63

That is one of the applications in the total DuDu firmware that delivers "base" functionality between the hardware, like CANbus, and "the rest" of the DuDu firmware.
You can download newer versions from the DuDu appstore on your unit.
Note though that this is probably a beta release of this base apk. You can only download those if your set the appstore to allow downloading beta software.

Thanks. I have beta on and updated the server and vehicle apps from the app store. Thanks
