2007 A4 cabriolet 3.2 ECU Fuel relay location
 

I took car in for airbag recall. They did routine stored code check and recommended "Replace both ECU Fuel relays and center brake light unit." (To the tune of about $800.)
In the past 12 months the car cranked but did not start on three occasions. I waited a few minutes and stated right up. I am assuming the ECU relays could be associated with the non-starting.
I've googled to find the relay location and they seem to be in one of two places: Under hood in computer compartment or under steering column. I started to look under the hood but need to buy a puller to remove the wiper arms. Before I do that, does anyone know definitively?
I'll get to the trunk brake light issue later. Tks
