Stanislav
Founder, ACD/AYC Pumps
I started ACD/AYC Pumps in 2010 and have been restoring Mitsubishi Evolution ACD and AYC pumps ever since — more than 1,000 units so far, each one torn down, rebuilt, calibrated and bench-tested before it leaves the workshop.
Most of my work is the same detective job: working out whether a warning light is the pump, a sensor, the wiring or the fluid, so owners don't pay for parts they don't need. I write up what I learn in the guides on this site.
If your car is showing ACD, AYC or S-AWC faults, send me the codes and I'll tell you where I'd start.
