had the van motd today and was pointed to an oil leak from one of the pipes around the turbo,i am going to replace both as they are quite corroded , my question is, is this a straight un bolt and replace job or does the turbo have to be loosened/removed to enable refitment of the new pipes, the 2 pipes in question are the large bore one from the sump to the turbo and the smaller diameter one from the turbo up in to the block they both have a flex type mesh fittings in the centres... any ideas appreciated...

The steel braided oil supply pipe from the sump to the turbo can be removed without taking the turbo off.Just loosen the coupling nuts each end of the pipe and remove.

thanks camper...

I agree with Camper as I replaced the flexible return hose on mine without any problem. I took the hose to a specialist hose supplier (Hyphose of Poole) where they made one on the spot for less than 1/2 the price of VW.
I'm pretty sure you can take pipe off without taking turbo off as I've had turbo off mine leaving pipe in place which means you can at least get to that (difficult) end.
Remember to prime pipe/turbo/hose with oil before starting as all oil will have drained out when removing return hose.

is that neccesary as surely they all drain when you do an oil change??

In this case I would definitely prime it because you would have definitely drained down all oil in the turbo as you've had the pipe/hose off and there'd be no airlocks to hold any oil in the turbo. Doing a normal oil change perhaps it's not so vital as you'd still have some 'old' oil hanging round in the turbo bearing. But for absolute best practice when you've refilled with fresh oil crank the engine for 5-10 secs to get oil into the turbo. To do this there's a cable going to the injection pump which you can disconnect which then allows you to crank without it firing.
Hope this helps!

cheers brookie it certainly has mate many thanks...lee

Its the black wire with a spade connector feeding the fuel cut-off servo valve... handy to know about this one, esp. if you ever knock it off or forget to connect it back up
