Hi Everyone,

I’m really hoping you can help. I have an A3 that is leaking coolant. I took it to a garage and they have said it’s the heater matrix pipes ( part numbers: 3C0122157 FB and 3CO121073 AA) the garage checked with the dealer and others and these parts are no longer made. I have looked on the internet and can not find any of these parts. 
 

Has anyone had this issue before and if so did you find a solution? 
 

Thank you for reading I appreciate any help that you can offer! 

Emma.

I don't know these particular parts, but it would be worth investigating a secondhand heater matrix from online car breakers.

Thank you for your reply this was going to be my last resort, as I was hoping to find new as they have been so hard to find I do not want to have to replace them again at any point in near future.

I have never needed to use the company so I have no idea about its service.

Hi can the garage not make up new hoses from silicone pipe as most of the connection ends are available on the web, if not contact a hose specialist show your old hoses and see if they can come up with something.
