What does SWaP mean?
SoftWare as Product (basically you tell the servers in Germany to add it to the options on your car so that any new update of firmwares don’t remove them) you can check out what products you have by looking at the FEC’s listed in your MIB
Basically a upgrade that you can buy (although there are other ways now that don’t require going through VW’s main servers in Germany)
But also some cars if you enable performance monitor the gauges read zero due to either incorrect hardware or firmware
I could go on and tell you how FEC’s work but that’ll probably bore you😂
