My 2001 octavia 1.9tdi 110 has developed an oil leak from what looks like the air intake above the driver side front wheel. The car has done 200k but apart from this leak, is in great shape. The leak seems pretty bad and i am beginning to think the worst, Any advice.

Is this a dupe or did my post dissapear?

If my post went, and assuming you are driving an RHD car, the air intake is on the passenger side, but on the drivers side is the intercooler, which could possibly fill up with dirty crud as the EGR is sending exhaust gases through it.
