Ok so spoken with dealer today, they have taken car out on several test drives, one of hem by a Tech who wins a MK6 GTi and plugged into diagnostics and ave confirmed car is showing o faults and is driving 'normally'.
They asked if there is anything else I want them to do, which I am happy for them not to as it has appeased my mind all is fine with the car.
Oh and for the best bit, no charge from dealer, very happy with the service
