TMPS Retrofit

[M-A8]

...also, over the years I have noticed that Audi parts which have the same middle 6 numbers are almost or same parts, if there is a difference then its always a cosmetic one.
For example:
The A5/S5 steering wheel or airbag is exactly same as D3 (function, connection, fitting), yes, the first 3 numbers/letters are different but they are only a platform IDs (4E0 Audi A8, 4F0 Audi A6 and so on).

For example S5 steering wheel PN is 8P0 419 091 DT and A8s is 4E0 419 091 AC and A6s is 4F0 419 091 AQ
Fact is all three are exactly same wheels and they will fit each of the models.
Usually, this is what I have noticed so I'm not saying it's 100% true, the last letter or two will describe the cosmetic difference or extras such as paddle shifters or being just a later revision of the same part, but they are same wheels using same air bags and same buttons.

Same think I found out when fitting chrome window switches, the part number is A3 part number and they are from A3 not A8, they were never available in A8, but they are the same part with a cosmetic difference and guess what, all 6 numbers in the middle of each part number are same.

Where I'm heading with it is that the TPMS wheel sensor which I can get brand new for £30 OEM Audi part starts with 7PP not 4E0 or 4F0 but the 6 middle digits are the same.
On top of it they both are 433MHz frequency as clearly printed on them and there is no physical connector so it's not like they are same but they take different plug.

Sensor in question is 7PP 907 275 F
A8/A6 sensor is 4F0 907 275 D
