I've got big polystyrene number 1, with 2,4,5,6,7,11 but 3 has vanished. Not sure what 12 is but don't think have that either.

3 is just like what the 406 has.

Thanks Marc, as usual! :)

It's an HF aerial for under inflation detection.

How strange - the workshop manual PDFs have it as an HF aerial, the parts manual has it as a LF aerial. Perhaps it's medium wave :lol:

Well of course, I knew that all along and was just testing you.... :lol: :lol: :lol:

For some reason I had the idea it was hidden in the wing somewhere where the ECU is! Well sussed Robin / Richard.

It is the Chinese 5G tracker and Covid injector. Bill Gates sticks them there.

I thought it was either some kind of receiver for the tyre pressure monitors? Or was a motion sensor.
Well done to Bobins and RichardW, guess y'all and Graems are our winning driver(s), like the three drivers in each le mans entry :-D

No, spot in, it's the LOW frequency aerial for the TPMS, there are 2 different systems on the X7, but for vehicles fitted with this particular system you can see the component that I've marked at (15):
