Thanks for drawing my attention to this post Tony - in its proper forum! However, you will no doubt have noticed how few threads there are in the TT forum which is why I generally seek advice from A4 owners.
I don't know whether the spring clamp was the original fitting (it looks much too low-tech for Audi), but this is what I found several inches down the hose towards the block. Nothing else - and of course the hose and the spigot were no longer joined.
After I had my little episode back in August with the wallaby (on Wombat Road on the way to Wombat, natch), the car was repaired extremely badly by GIO's preferred repairer in Queanbeyan. There were numerous faults including the front bumper and new headlamp not being bolted on properly, fans not working, panels not lined up. So I took it to Anthony Costello's for him to straighten out and give me a report for the insurance company so I could claim the cost of remedial repairs. This was to be accompanied by a written report for the insurance company but the latter has never been delivered in spite of repeated requests. I guess writing is not their forte. The remedial repairs are great.
So it's most likely the original repairer removed the radiator or possibly just the hose, and failed to bolt it back up again. After all, they took the splash/sound insulation panels off the bottom of the car and failed to replace them, broke one of the panels at the front of the engine and cut or tore the rubber seal at the back of the engine bay...
The other possibility is that Costello removed the hose in his efforts to get things bolted up properly, or to get the fans working again. So either the clamp moved itself whilst I was logging (unlikely as stated) or it was moved by the body repairer in August or by Costello's boys in November. What a mystery
