I'm guessing the EDS is the ELR in my case? The three controller relays in the car are ELR, EGR, and KLIMA. EGR I've had unplugged. I can see three caps on the board, think I actually have some of the right values around somewhere, but the board is dirty as heck, definitely gotta resolder everything.
