(There were also other issues with the brakes grabbing) There’s definitely an issue with the turbos on this engine. Some have it some don’t, mines now at 1800 miles with zero whine or whistle whatsoever. How many miles now?

What does turbo whistle sound like?
As the name suggests, a turbo whistle sounds like a high pitched whistle or whining sound, heard when the turbocharger kicks in as you accelerate and the revs go up.

For some people, a turbo whistle can be annoying, but to others, it’s actually desirable! In fact, some people purchase aftermarket ‘turbo whistler’ devices that fit inside the exhaust of a vehicle to mimic the sound of the turbo whistle.

A turbo whistle shouldn’t be confused with a police siren or dentist’s drill sound – this is likely to be a sign of something more serious, like compressor wheel damage.

So yeh, dentists drill or 'police siren' sounds (no idea what that means) is bad. The 'good' sound I hear from my turbo is more space-age scii-fi noise, not a 'whine' as such.

Definitely a whistle. Anyone know how I can post a recording?

Ok Technicians - all with a different opinion

Our replacement Seat makes more Turbo noise and it is supposed to be exactly the same as the old one

Do I care

Nope !
