Hi, I'm owner of of VW Golf VII 1.6 TDI, Year: 2013. Recently I upgraded my vehicle's infotainment system by replacing it with a LENOVO SSW 10747_CPA.
After this upgrade, everything works fine, but I received an error on dashboard: "Error: Tyre Pressure Monitoring System" and the icon of TPMS remains always on on my dashboard.
I tried to reset TPMS inside of the menu of Lenovo but nothing changed. The installer changed some ecu back of the Lenovo but the issue still persists.
Is there a way to use OBD Eleven in order to code TPMS to cooperate with Lenovo and stop this annoying message?
Best regards

markospap : Hi. First, when you refer to TPMS - I assume that you refer to indirect TPMS (the form of TPMS that does NOT use pressure sensors in the tire valve stems)
Of course the LENOVO is a very non-OEM device - meaning that OBD11 can only talk to it to the extent that it simulates the factory MIB. I don't know the answer to your question, but if this was my car - I would SCAN the car to see whether (and how) OBD11 reads the new device. If OBD11 recognizes the module, I would look at how LENOVO treats the adaptation channels related to TPMS - specifically these: Vehicle function list BAP - tire_pressure_system_0x07"> active
- tire_pressure_system_0x07_msg_bus > Terminal 15
Vehicle menu operation- menu_display_rdk "> active
- menu_display_rdk_over_threshold_high "> active
If you can't read these channels in the LENOVO module - I suspect the only recourse is to disable TPMS entirely from the car (or contact the seller)

Dear dv52, First of all, thank you for your direct answer.
As you may see on the image below, OBD11 cannot read LENOVO at all.
5F is disabled at all.
Moreover, module 65 (Tire Pressure) is disabled too:
This is the menu of Lenovo about Tire Pressure:
And this is the error message on dashboard:
Of course, I refer to indirect TPMS and not the TPMS that use pressure sensors in the tire valve stems.
Moreover, please inform me where I may find these commands in OBD11:
Vehicle function list BAP
tire_pressure_system_0x07"> active
tire_pressure_system_0x07_msg_bus > Terminal 15
Vehicle menu operation
menu_display_rdk "> active
menu_display_rdk_over_threshold_high "> active
Best regards.

Dear newty, Thank you for your direct answer.
I try to do: Reset tire pressure monitoring display warnings but I receive this message:
Moreover, I think that the solution of a dedicated button will be a more trouble for me, to install it.

markospap : hmm..............I know absolutely nothing about this Lenovo and I'm guessing of course - but I suspect that the problem here is NOT a coding issue.
If you look at the Lenovo screenshot in your post - notice the "-.-" entries next to each tire. These symbols suggest (to me at least) that the lenovo is attempting to show the actual tire pressure in each wheel. However, because this car uses the form of TPMS that does NOT have sensors in the valve stems - the Lenovo has received no pressure readings - hence the "-.-" symbols
So - if you want to fix this problem, I suspect that there are 2 x options -either: - Retrofit Direct-TPMS - or,
- Change the option in the Lenovo to Indirect-TMPS.
I don't know if Lenovo has an Indirect-TPMS option

Hi Don, Thank you for your reply. I will contact with Lenovo in order to update my infotainment to be compatible with inderect TPMS, otherwise, I have to change indirect TPMS with Retrofit Direct TPMS.
By the way, is this change easy?

markospap : retrofitting Direct-TPMS into this car means adding a new control module, installing a new wiring loom, fitting the 4 x pressure sensors on the tire-stems and making coding changes. Direct TPMS also needs a High-line CAN gateway module (not sure what version Gateway module is installed in this car) There's a few conversations about this project on this forum - search for the term "Direct TPMS" Don
