Coolant Hoses

I am fighting with coolant leaks again. Does anyone know a good place to get part 8Z0121052? Has anyone replaced the oem hoses with aftermarket performance hoses?
 
 
Another problem! This time part 8Z0121101AD broke. The plastic T connector snapped at the joint. Lost all the coolant again and had to get towed home. Might be good if someone sold a replacement/upgrade kit for the whole FSI cooling system.
 
Another problem! This time part 8Z0121056A sprung a leak. Just phoned Audi and they said they don't do this anymore. Any suggestions?

You know I was only thinking the same recently and what a good idea it would be to be able to purchase and replace all the perishable hoses in one go but not just for the FSI but for all models ?
 
Trying to find the other pipe as we speak...

Same problem, hose to oil cooler, 8Z0121056A - zero success on replacement, all websites, so great to find your solution. My coolant leak is at the oil cooler end of the hose, and could be a problem with the oil cooler itself. Could you let me know where on this hose your leak was, and can you please confirm the generic 18mm replacement (still available!) and if it's still in good nick. Cheers.
 
The part that gave me trouble was 8Z0121056A. It's been over 20 months now, and I haven't encountered any issues since. The link still appears to be functional, so feel free to give it a try.
