When you know that one of four wastegate solenoids are bad

Customer Question

When you know that one of four wastegate solenoids are bad is it absolutely necessary to replace all four?

Hi there,

It is more of case if the individual solenoid is serviced separately.

If it can be replaced on it's own and it is the only fault, I would not see any reason to replace all four.

It then comes down to personal choice.

Myself, I would only replace the faulty one if possible.
