Got the LPFP controller and associated harness swapped out. Got a datalog and the DC is down to 60% at the highest.
Regarding the A2B Motorsports harness for the LPFP…
I know there aren’t many S3 guys on here but I found that the ground wire isn’t long enough. In the golf platforms the stud is on the seat pan and closer. In the Audi it is next to the seat belt anchor behind the trim and sticks out horizontally. The ground wire reaches but you’d never be able to put the seat cushion back in because the wire doesn’t have enough slack to lay flat. I cut the ground wire off my old style harness from the silver controller and used that because it had plenty of room.
