Well the first positive was that on arriving at the garage the Master Technician attended the car with me to assess the snags/ the issues on my list... and the whining noise came on immediately when reverse and when first gear were selected!
Of the noise, he immediately said that to resolve it, 'it's a gearbox out job' to replace parts that will probably include replacing the throw-out bearing return spring. He says it's 'a day of job' for this job, subject to the parts being available.
All of the issues on my snag list, the garage has, without quibble, said they will address without charge and a courtesy car has been supplied.
If issues such as this were not addressed, even if deemed non warranty and non mechanical failure (only had the car 2 weeks mind), then I would simply reject the car and ask for a refund (which I would not want to do as it's a lovely car).
However, there has been no argument at all here, just a stated desire by the garage to resolve all and I'm very happy with the car and with the after sales service which to date, seem first class.
