Hi my 320d f30 overheated the other day due to a air lock but now seems like my turbo has started leaking oil into the dp is this a common thing as i see turbo is water cooled ?

The turbo is oil cooled, check the banjo bolts around the feed/return pipes.

Thanks bishbosh bolts all seem tight does this mean the turbo needs replacing ?

It'll need a rebuild more than likely

When I first collected my 325D I had a slight oil leak from it (smoke after it'd been hot for 10mins or so); it was fully rebuilt by the dealer thankfully

They used Turbo Force up this way in Preston and they're highly recommended also
