AYC faults are becoming a problem for many Mitsubishi Evo owners. We’re seeing more and more cars displaying the dreaded ‘three AYC lights’.

A common cause of problems with the Evo range is the Active Yaw control (AYC) pump. The AYC pump commonly corrodes internally, breaking seals and increasing distances between components, which need to be within a fine tolerance for the pump to produce pressure.

But don’t worry, a solution is here! If your car is suffering from low pump pressure or a faulty solenoid we can help.

Our AYC pump rebuilds use new bearings, new pump sandwich plate, seals etc. All our AYC pump rebuilds are on an exchange basis, and we can also remove and refit the AYC pump from/to your vehicle including bleeding the centre and rear diffs, depending on your model, be it an Evo 4, 5, 6, 7, 8, 9 or 10 (iv, v, vi, vii, viii, ix or x)

We now offer Full AYC pump rebuilds on your old unit (POA). There are however, very few cases where these pumps are beyond repair, so please bear this in mind. If the pump you send us is unserviceable, we will Still charge labour for the strip and inspection and postage back to you. We do buy old pumps for parts.

If you’re stuck for time and don’t want your car off the road too long, we also offer a part exchange ‘Drive in drive out’ service.
