Where is my ESP sensor unit G419? Please help

[MattW]

Hi,

2008 8P 2.0 TDI

Please help.  I have an error with the lateral acceleration sensor G200 it needs replacing but I can't find it?  In the 8L model it was under the steering column. Reading this https://workshop-manuals.com/audi/a3_mk2/brake_system/abs_adr_tcs_edl_esp/removing_and_installing_parts_of_abs/esp_system/removing_and_installing_esp_sensor_unitg419/ 

it suggests that the G200, G202 and G251 are together in the ESP sensor unit (G419) located under the right hand seat (under carpet).  Ive taken a look under the carpet but I can't find it? Its driving me mad!

Can anyone help me to find my ESP sensor G419?    

Thanks!
