HELP Bad day at the garage fault code list as long as my arm. 2.0t fsi

Had the managment light up for a while on my a4 2.0t fsi so thought best take it to my mates garage and plug it in. So once i pulled the codes the results where:-

P2181-performance malfuncation in cooling system
P0299-boost pressure regulation control range not reached lower limit reached
P0441-EVAP Emission control sys incorrect flow lower limit reached
P0507-Idle control system rpm higher then expected upper limit reached
P0704-Clutch switch f36 implausible signal no signal/no communication
P2279-leak in air system lower limit reached intermittent

Anyone else ever had any of these problems and have any advice cheers.

All codes have come back up 2day so will have to get my hands mucky first job check for air leaks and change dv I think. Cheers all for your advice.
