I bought 4 tpms from AliExpress to my car M40i
After fix it and code it by Carly
It not work
Need advise
What to do
What is the wrong

Do you mean your car wasn't fitted with TPMS from the factory?

In which case, does it have the receiver(s) for the TPMS system?
The TPMS sensors send a signal, there must be something which receives that signal. Do you know if your car has that?

Perhaps the clue is on the picture... “Made in UK”.... where it should actually say.... “Copied in China”...or perhaps Crap from China... I’ll let you know how I make out with real Schraders from Rock Auto....

Like me, they are probably adding to a second set of wheels...instead of having to clear the error on start-up...

Yes car was not fitted with tpms from factory which show " temp and pressure "

I want to know in general after fix it it work direct or need coding or fix control to receive signal ?

From where you bought it
and will wait your review on it
Your car do not have tpms like me
Trader till you it will need coding or configure automatic

Sorry, did you car not have TPMS at all?
Or it already had pressure and you are trying to add temperature?

My friend bought a 2019 M40i last Nov...he did not install TPMS on the rim...and has to clear the fault each time....I don't want to do that...So figured they were needed.

I don't even know if our X6M and F25 have TPMS in the wheel...on our winter rims...but have never had a fault light...and they complete the pressure relearn procedure...

Earlier versions of TPMS used the ABS sensors (and steering angle) to calculate wheel speeds and establish when a tyre had significantly deflated. Much simpler system and therefore pretty reliable. The good old days.

I want to know pressure in each wheel

As verysideways pointed out, believe you need the receivers for that to work, otherwise only pressure would be available via the old abs sensor route, but even that will not give you pressure per wheel but rather if the tire is simply losing pressure

Winter boots with the Schrader TPMS installed, are now fitted to the vehicle....

Vehicle noticed the change and the reset to 100% was easy...

Normal service restored....
