Oil seepage on a turbo with 80,000 on it yes i would agree but so new i would not.
From research and help from others and this thread also its not the turbo its the crankcase ventilation system causing the oil vapour. Then the air inlet pipe and ventilation breather pipe leaking causing that vapour to turn into oil. Now if it can leak oil it can leak air.. An intake side of an engine that leaks air... normal... I don't think so.
Read the info I posted about the crankcase ventilation system and how it works it may help.

well got home from work today after being away all week, my wife had taken the car in for the service. All the service paperwork said was , turbo oil leak £1300 to fix.

Seems to me they didnt even look if any of the pipes were leaking, to hard for a dealer to actually try to see what the problem is, no way the turbo can be knacked after 30,000k. The service guy said not to worry about it it wasnt urgent, seems like a cop out as the oil leak was identified on the MOT when it was still under warranty

Going to see them on Monday armed with this thread printed off, see what they have to say then. Im really getting disheartened with the standard of VW dealers. Whenever i have a problem it always seems to much trouble for them to bother to try to solve it, i shouldnt be telling them what is wrong. £1300 isnt something you just have lying around especially when that probably isnt the problem.

Im afraid to say i really dont think i will be sticking with VW, once this prob is sorted the car will be going. This is my third GTI not sure what has happened with the quality but my 2  MK5's never had any issues

Mk5 suffers the same problem. But its slightly different, the oil near the turbo is the same but its normally the pcv valve that fails on them or the fine oil seperator or diverter valve. All can produce this same looking 'turbo failure'.
Check the two links I posted to the no5 forum it shows what happens on the 5.
VW improved the crankcase breather system on the 6 but it seems to also suffer but in a slightly different way. Quite a few reports similar to this topic on the net too.

Check your two airway pipes on the top of the engine for any signs of oil.
If not that.
If its more a spray pattern near the turbo the high pressure oil line is a known trouble issue too. It's a.simple bolt on pipe near the turbo.

Cheers snoopy, after having a quick look yesterday before it got dark mine looks like the pic on page 1. Sort of caked on oil around the big down pipe at the rear top left as you look at the engine, will have a better look today.

Check the small pipe too. Mine looked ok until I rubbed it with my hand and there was oil on the bottom of the join which has been dripping down.
You may have to remove the engine cover but that simply pulls up off its 4 push in fittings.

Well snoopy i think u have cracked it, just felt round the bottom of that small pipe that joins the main large black pipe at the rear top left. There is proper wet fresh oil all around it, i guess its dripping down from there.

Will show the dealer on Monday when i go to speak to them

But from my limited mechanical knowledge, i thought the pipe i have oil on is only for air

Been doing abit of reading, i gather that small pipe comes from the fine oil seperator thats why it can leak oil. Learn something new everyday

booked into VW Boston on Friday to get the oil leak sorted, yet to give me the price until they have looked at it, seeing as they couldnt find it when it was in for the service last week, all they said was turbo leak £1300 to fix. After Snoopy,s advice traced the leak myself to a pipe joint.
