Air tube from turbo to inlet manifold

**LRD414** · 10th May 2025, 05:29 PM

I have a 2L turbo petrol Freelander that has an air tube from turbo up to inlet manifold that’s broken off at the inlet manifold end. What I’m wondering is why there’s a connection from turbo to inlet manifold? It’s not a vacuum solenoid line as far as I can tell. Is it just to make sure there’s no pressurisation or pressure differential?

Cheers,
Scott

Some kind of equalisation tube id imagine, I wasn't aware there was a turbo petrol engine in a Freelander ?

Ford EcoBoost?

Yeah the 2L carried through to Evoque and Disco Sport. Not sure there was that many sold and yes, I’m pretty sure it’s the Ford Ecoboost

I've only ever seen the 3.2L 6 in the FL2, must be a late model then.

Is equalisation a common thing for turbo engines?

There may be a solenoid that requires manifold pressure to operate.
