The following is the mandatory bare minimum for option S716A (Front Aerodynamic Trim). For option S715A (M Aerodynamic Pack), many other items are needed
If you are converting a LCI front bumper to M-Sport bumper and have PDC option (L508A), know that PDC sensors are different in shape and size. LCI sensors have a diameter of 18mm, are smaller and have a separate rubber gasket while M-Sport sensors are longer, have a diameter of 24mm but have no gasket. So you need to purchase M-Sport PDC sensors if they are not included on the used bumper you are swapping in. Before installing them, if they are in a different color than your car paint color, you need to sand them with slightly wet 1000/2000/3000 grit sandpaper, gently. Then spray them with a thin primer, plus a thin coat. Professional garages use a special primer for PDC sensors as well as a special spray nozzle. Before mounting, make sure they are in a working condition by measuring the resistance between pins. The specified operating values are as follows:
Front M-Sport or pre-LCI PDC sensor (24mm) (Part Number 66202180148. OE is VALEO)
Front PDC connection socket pins
Front PDC sensor pins
If the resistance measurement between two pins returns no result (Open Circuit), flip the multimeter terminals and/or choose a more adequate setting
| Resistance between pins | 1-3 | 2-3 | 1-2 |
|---|---|---|---|
| Healthy Range | Greater than 0.5 Mega Ohms | Between 2 and 45 Kilo Ohms | Greater than 0.5 Mega Ohms |
| Ideal | 1.07 Mega Ohms | 40 Kilo Ohms | 1.07 Mega Ohms |
