What other items are suggessted then?

It looks like the engine in my S4 will be dropped shortly. The service documents mention a rattling heatshield on the left side, which is where the turbo is playing up.

With the engine out, this will be a good time to attend to other bits also.

OK. resurrecting an old thread... Turbo failure, left hand side, from inside the car, when boost is building, it sounds remarkably like the sound in the preceding clip. In addition, there is a rattle at idle. Is it fair to 'suspect' then that the manifold has separated internally? What is the exact ...

When it is functioning, what indications are present?

Hi Have just bought a S-plate S4 saloon. It's quite a hoot. A little tatty externally, but serves the purpose at the price.
