My audi a3 2.0 turbo (2006) didn't start

servicii_2013

Hi,
My audi a3 2.0 turbo (2006) didn't start and we read its computer and gave us 2 codes: 1) U0100 (ECM MODULE); 2) P0688 (RELEY COMPUTER DATA). Do you have an idea of what the problem is by analyzing the codes; the car is still not starting. Also, I would like to know if you can tell me where the car's computer is located. Thanks!!!

i think you should check grease oil. and for more information you should take your car to the mechanic.
