Hello. First sorry for my bad english.

Second I have a4 1.9tdi 131ps quattro ( b6). Last week i noticed some strange sound. Yest. me and friend lifted car up and noticed that sound comming from quattro torsen differential bearing. I asked on audi service and they told me that i cant get only bearing but need to buy whole quattro torsen differential which is around 1k € :/

Now i dont know what to do.. Can i put it from any other car?

Any help pls :=)

 

Its squeaking sound. Realy anoying. Friend told me that mybe can be that gum around bearing??

Any1 know what to do at this problem or. what can be problem?

 

I never of that problem before. I know that sometimes the transmission makes a whinning noise but other than that I don't know much about the center differential.
