Why isn't the turbo in my 2018 Ford Transit working?

Asked by Don

The turbo in my 2018 Ford Transit is not working, it just whistles. Is there a bearing that can be greased or could something else be the problem?

You’re on the right track, Don, with your guess that the whistling noise has something to do with the turbocharger’s bearing. But unfortunately, if you’re right and it’s the turbo bearing that’s making the whistling noise (and I agree with your theory) then a new or rebuilt turbocharger is the only real fix. Turbos have a hard life, dealing with extremes of temperature as well as the requirement to accelerate from almost nothing to anything up to 250,000rpm. The bearings that allow for this are sealed units and – generally – are not serviceable.

But you might be lucky: A lack of turbo boost can be caused by many things, so check the basics like a loose boost pipe before you start tearing the engine apart.
