957 Turbo 4.8 Cam adjusters

Hey guys

Im seeking some info regarding the Cam adjusters on the 4.8 in the 957.
Has anyone got experience with these things becoming unresponsive and setting DTC's for P0016?

Has anyone removed, disassembled and cleaned them and reinstalled?
They're hugely expensive to buy new and it looks like no aftermarket options at all.
Can they be cleaned like the Vw/Audi ones?

They are different to the all common 958 V8 unit failures

Thanks
