CODES SOLUTION

Hey guys!

Sorry for my english It's not my native language, anyway I've own a Skoda Octavia A5 2008 Diesel 1.9 - automatic transmission... Days before the car start to flooded the passengers foot when the A/c was on I didn't give it much importance so I didn't use the A/C a lot. The thing is that some days after on a red light it suddenly turns off, I tried to turn it on but It fails. I bring it to the mechanic makes me change the battery, mesure the pressure of the back fuel bomb, but it was fine, and in conclusion he said it was an electrical problem. But he check the fuses and all were fine. And when he check the computer it brings this three codes, P1626, P1648, P1649.

So before going to another mechanic I need some advice or clue if you know something about this codes?
