Well I'm a regular on
www.disco3.co.uk and compared to the number of vehicles on that forum, the number of software issues is minimal.
Where ther has been a need for software to upgarded, the exact issue has been indicated in the thread. Can you elucidate and provide links to theses numerous faults with no problem of which you mention??
Everyone needs the odd fault cleared at service (very few of which will stop the car and some of which the driver is even aware of). Having to visit the dealer the have fault code resets for non-continuing problems is a TD5 thang, not a D3 thang!
