Sudden DTC's, Climatronic not working!

[Elcroato]

Hello,

I was beating the crap out of my 1.8T, remapped with Revo StgII, when I noticed the RPMs would continue to climb a bit after shifting. I then noticed the AC was dead.

I pulled over and ran a VAG-COM diagnostic. I have three sensor faults. Brake light switch faulty, oil pressure switch faulty, ambient temp sensor faulty. While testing, the coolant temp went up to 110C, the needle was 3 quarters over. The cooling fans kicked in at that point and lowered the temp back down to around 100C. My Climatronic has no power. I cycled the ignition. I reset the codes. Still no power. I tried disconnecting my MAF sensor and that fixed the RPM issues. The brake lights work fine. The fuses are good. Help!!!!!!! I live in Sicily and have no one that can understand me here.

Codes: 00562, 00667

I went through the fuses again today and it turns out it was a fuse! Fuse No.5.(7.5A). I replaced it and cleared the codes and everything ran well. However upon further testing it would blow everytime I'd go WOT and above 5K RPM. I also drove over lots of potholes to see if that would cause it to blow and it didn't. So what could cause that circuit to overload when driving fast?
