Actuator problems.

Hello, i've been trying this entire weekend to search for what could have happened to my car but theres so many different things and none of them which match my fault codes and problems 100%.

Car in question is a 1.8T mk1 Leon Cupra4. (180)

So what has happened was that i was out driving and came to a steep tunnel and was boosting what the turbo is good for. then suddenly i lost all power and my dashboard litt up, EPC, ESP, check engine and i lost all power.

pushed the pedal to the floor to no avail. tried to stop the car to turn it on and off, but the idle was rough and the pedal was dead. tried to disconect the battery to see if it would reset, it did but the problem was still there.. got towed back home and i just got it scanned today. Heres the log:

so does anyone have any pointers as to where i can begin to look for faults?

Would it be possible to check somehow?

Ok, so got around to look at the car today. took off the pipe that goes on to the throttle body and tried to see if there was any movement, could this have caused it to missalign? anyways it did not respond.

But at closer inspection, the clip that goes in to the throttlebody was loose so when that was plugged in, the car started working again. but there was one problem - the idle was rough and the throttle response feels slugish. could this possibly be fixed with a TB allignment?

Okay, disconecting the battery didn't work so i went over to a mates house who has the vag com cable and got it alligned and the problem is now gone!
