Turbo not boosting

[Benny2tatts]

Hi guys, has anyone had issues with the turbo recirculation valve sticking open? I’ve a 200thp and it’s not boosting at all. Diagnostics say’s valve is stuck open. It’s fairly cheap to replace and easy to fit, just wondered if anyone has or was experiencing the same issues. Thanks.

If you mean the electronic diverter valve it can be the seals are leaking its another generic consumable on these engines

So, replaced the diverter valve, still have the same issue, I did previously change the thermostat housing, which now houses the coolant temp sensor, with a harness adapter. Would this affect things does anyone know?

Coolant issues won't affect the Turbo you need to check of the Turbo gasket & pipes for leaks take off the inlet hose & look inside to inspect the impeller if all is good it may be the waste gate is sticking or a actuator problem
The code for low Turbo pressure/boost is usually P0299
