On inspection the LDS fluid is welling up around the body of the ECU and running down onto the pump body. There are 4 brass holes in either corner of the ECU, it's around this flange it gathers. There are no obvious signs of leaking around here. It's very slow, and seems to come and go at random. If I park up on the kerb drivers side it seems worse. Proper head scratcher this. I could strip it out but wondered if there was any area to zoom in on first, it's a messy job as we all know.
