Test the various posibilities, The following information helps to isolate and fix the issue
| 1 | Ensure the correct procedure for setting up via the MMI is adhered to |
| 2 | Are the batteries in the sender units still viable |
| 3 | Is the control unit correctly coded, Wrong coding may mean that the system is checking the wrong frequency |

Does the system recognise all in the sensors fitted in the vehicle? Read measured value block 16 which shows in turn all receivable sensors. 4 different numbers must appear (5 in case of full-size spare tyre).........
