Mine has it as standard, but the only thing it reports back is the due maintenance and if there were any errors (which of those would be displayed here, I don't know) ...

Silly me. Yes it has a "CHECK" button showing the same as above but nothing related to TPM

Which would probably mean you don't have TPM in your car ... :) ... what you're missing is 2 or 4 transmitters for the wheels (around 60 GBP each), the TPM module and TPM antenna, that are in the back of the car (side of the wheel, under the cover, and in the spare wheel compartment ... at least that's what is written in the service documentation, I haven't had the chance to see a car in full detail whit the TPM) ... and of course programming with DiagBox ... :)

Not sure how I can tell if it has TPM or not if it reports the same as your C5 that has TPM. I think you should be getting a different screen if your C5 had TPM.

Whoever said I have TPM? ... the sure way would be to first check if you have the receiver and antenna in the back (at least easier than getting the tyre off from the rim) ...

Easier still, look at the valve stems. TPM stems are usually solid metal (aluminium?), as distinct from the usual brass / rubber construction.

True, but the valves on the wheels don't mean the car actually has a TPM system ... :) ... I can mount pressure senors on my wheels, put them on the car, and no error message would be given ... since the car doesn't have TPM ... :) ... sure, an extreme example, but, not impossible ...

That's why I am asking. Two of the tyres have a metal stem. I suspect the car came with TPM and the previous owner removed it.

Car overview (1 - location of tyre transmitters; 2 - antenna; 3 - compute/receiver):

Image

The computer should be located under the rear left wheelarch cover (inside the boot), as show on the picture below:

Image

As for the antenna, it should be on the carriage of the spare wheel (inside the boot):

Thanks for the photos, great! Is the wiring ready for the Confort models, even if the receiver and the antenna is missing?

I'm not sure to be honest, I still haven't checked this in my car (although I have it on my to-do list) ... I don't think so, since some other things that are missing don't have any installations which I've already checked (i.e. headlamp washers) ...

Well it's got TPM as it has the receiver and the antenna. As I am not getting any error messages it is disabled. Good to know if I ever decide to enable it.

Was there a question of "if it is fitted it has to work" or it's an M O T fail?

With normal tyres there is no question.
