Proposal list of spare parts not available

Hi, you.
since I was allowed to hear the saying again at the Audi dealer: is e.o.E I thought it would be not bad if we could gather our experiences in this area to a list. Here in the forum there is perhaps the possibility to officially adjust something like this. What do you think of that? It's really frustrating, if you order something, wait a week and then you hear that the whole order could not be delivered because there is no way! Maybe you could create an input mask where you could enter the spare part number and the name. So please, one to the admins!!
