R36 help- DSG or flywheel?

[Radius]

Hi everyone,

After 5 years of faultless running since new, today I had my first major mechanical.
Our R36 has now suddenly developed grinding and clicking noises while under load, particularly accelerating in lower gears on way home today coming off freeway. Also developed a whining noise on deceleration / downshift. The car then dropped itself into neutral with flashing D1 on the instrument cluster for 20sec before re-engaging drive. Babied the car the short distance back home with ongoing grinding noises and somewhat delayed up shifting compared to what I'm used to.
The car will stay garaged until I can hopefully get it looked at with VW next week. I was wondering if this is a classic DSG problem, and if anyone here with similar problems can advise what will need to be done to get back to happy motoring again
Thanks everyone for your help!
