UV style dye in the oil then use a fluorescent light to examine the engine?

What kind of oil would help narrow it down.

seems to be fresh oil dripping off the bottom of the alternator the dip sticks shows slightly over the max mark ,had service recent .oil filters in awkward place could be sloppy work , I will keep an eye on oil level monitor the amount of loss first ., a member posted using a uv dye then a fluorescent light .where can I get the dye ? thanks

To inspect the underside of the engine you'll have to remove the undertray - assuming it's still fitted. But first I would check the oil filter. Maybe it hasn't been tightened sufficiently or maybe replaced without fitting a new O-ring. To check the filter remove the top cover. It's tucked away under the front of the engine & over the alternator with a 32mm hex shaped top.

I removed undertray  and checked filter is tight, it clean not leaking ,I have wiped the area clean so I can see where its leaking from after work tomorrow, run up the m2 . its only a small leak at the moment .it looks like clean engine oil ,clear in colour thank for response I will check it tomorrow after work ,

With some luck you may find some was spilt when refilling the sump.

There shouldn't be any oil in the intercooler although some can leak past worn turbo bearings. The intercooler acts like a scoop in front of the radiator. The colder the air, the more the turbo can force into the cylinders.
