Recently my A4 would not start so I popped the hood to check everything out.
I noticed tons of blue/white corrosion over the positive terminal so I cleaned most of it off today with baking soda and water but the terminal is still stuck on the battery like superglue.
The cable also has bad corrosion growing in/on it.

One of the red wires covered with black split wire loom broke off that was connected to the battery(can some please help me identify these)

Sorry for the bad pics, my cell dosnt have flash
Need help, What should i do?

Should I replace all the wires/cables?
I rather not go an Audi Dealership, do local mechanics shops fix these sort of problems?
