Diagnose the issue
Before we start to rebuild your AYC pump, we recommend customers book-in for a diagnostic check. We will use MUT III Computer to identify the trouble code, we will also directly connect the pump to test if the pump itself (Eg: Is it building up correct pressure? Is it holding up correct pressure? Is it cycling correctly?)

Remove the Pump assembly and Bench work
Once the pump issue has been confirmed, we will remove the entire pump assembly from the vehicle, and start to rebuild the pump. Rebuild kits, Reconditioned components, Replaced parts will be used during rebuilding. We will also bench test and initial prime the system before the pump assembly fitted back to the car
