Suction Air Or Blow? - 850 t5r 95

Post by t5r spain »

Couple a days ago took of my t5r cluster.
The hose that fits to the back of the cluster for turbo indication was
suctioning air.
I´ve notice today it starts blowing air giving me a negative turbo indication value on the cluster.

Does this indicate that the Turbo has died...............
Thanks

You will have indication that turbo has died if the car fails to pick up speed agressively when you put your foot in it.

The hose is connected to intake manifold. Idling and very low throttle opening you will have vacuum. Over that and the turbo creates pressure in intake. The hose sucks and blows.
