Citroen Turbocharger bypass valve replacement
Does My Citroen Need a Turbocharger Bypass Valve Replacement?
If your Citroen is fitted with a turbo, the turbocharger bypass valve or blow-off valve releases the pressurized air in the intake when the throttle body closes, pressures can skyrocket and force air into the turbo in the wrong direction which can cause internal damage in both engine and turbocharger.
The bypass valve or blow-off valve releases the excess pressure either into the atmosphere or back into the intake.
There can be a few ways to tell if your turbocharger bypass valve needs repair or replacement:
- Poor idling
- A different sound coming from the location of the turbo when decelerating (fluttering)
- Air leak sound
- Decreased boost pressure
The turbo bypass valve is a relatively simple design, aside from adjusting the spring pressure most repairs involve replacing the valve itself.
If your Citroen has a turbo fitted, the turbo system runs under very high pressures, it is important to get it looked at as soon as you notice an issue. Delaying any repairs could result in further damage to your engine and/or turbo.
Not all Citroen's are fitted with a turbo, check your owners manual or ask your AutoGuru mechanic next time you book a service.
