IMO it will be 200,000km on engine before the sludge from EGR will affect the performance, of course there will be some engines which will clog up earlier than that.
cheers for the replies, guys.

in this case, i will just tend to it/ replace or rebuild turbo and clean manifold when time comes.

i dont think i'll be upgrading at that many km's. i want this car to last ages. the current pogo is one of the last small cars. by 150,000kms, the then polo will be the size of the current model lancer sportback

i heard that the turbo and intake manifold are one on the vnt's- is this misinformed?
