audi s6 AAN IC leak

[rs200]

hy people !
today I try to do boost leak test on friends S6 , and find out that IC have little leak .
few tinny hole on it .. maybe 4 or or 5.
could they make influence on strange idle ? because it stays on 1000rpm.
actually my problem is hot idle at 1000rpm.
there is NO some fault code or something else, it boost good , maybe a fuel consumption is little higher.
could it be from this few leaks on IC ?

Boost leak will make it run rich.

The problem with the UrS6 intercoolers is they used plastic end tanks instead of the cast aluminum of the UrS4 stock intercoolers. With time, the plastic end tanks separate from the aluminum intercooler core. Easiest fix is to find an all aluminum UrS4 intercooler and swap it in.

could it efect on idle ?

Probably. Any leak will have some effect. Suggest you fix the leaks and see what the effect is.
