Strange Electronic Malfunction!! HELP!!!
 

Well, basically here is my problem...

Whenever i get in my car i turn the engine on and set off its all fine, but then once i touch something electronic like the indicators or when the auto door lock comes on and even if i tap the brake.....my radio just turns its self off and then about 5 seconds later it comes back on? But sometimes it doesn't do it at all. To me it sounds like a loose wire or something? But i'm not going to lie, im not the greatest with cars so i don't want to mess about with anything...please can someone help me!!!

My car is:

Audi A3 1.8TFSI Sportback
57 Plate
31,000 miles

that does sound weird .... not sure what it could be, but maybe check the fuse first? it's something that's easy to check at least --- look in the owner's manual to see which fuses are connected to the radio
