Slight oil leak on turbo

[transitnovice]

Hi just been to check the oil level on my mk7 2.2 85ps and spotted a oil leak from the turbo it's on the join between the pipe and turbo on the right hand side looking at it from the front... it's not leaking that I can see when running at idle but there was a fair bit off old oil that was dried on and some fresh oil drops under the turbo / pipe join
Oil level is same as 2 or 3 week ago and van never looses any oil between services
Anyone had this before?
Should it be taken straight to a garage? Van is needed for work over next few days around a 200 miles round trip
Thanks
