Search for pla 2.0 or 3.0
The installation is simpel but takes time.
If you have pdc front and rear, you only have to add 4 sensors.
As the sensor have 3 wires, + and - and signal you can connect them to the pdc connectors.From every corner of the car its only 1 wire. (label the cables so installation is easier.)
You need a different middle console buttons as you dont have the pla button. (facelift is white background lighting, pre facelift red.) Of course the new console isnt wired. There are 2 wires from pla switch to pla elekctonics (above clutch)
You als need abs sensors in rear. (if you already have acc you dont need them)
last complete retrofit set (stock 8 pdc sensors) cost arrund 250usd on ali.
Coding get a hold of the famous spanish golf pdf. If your missing more sensors price is going up too.
Drilling the holes is not an issue. As the markings off the pla sensors are on the inside of the bumper.
Punches like these are perfect!
