Heya :)
so after the engine has idled for about 3-5 minutes there´s a fairly noticable dripping , off the engine carrier.

The hosing to the expansion bottle / thermostat / cooler are dry

The hosing to the matrix is dry

Im thinking ít must be off the coolant pipe along the head ?
the one you can just see between the strut tower and coil

After 10 minutes the leaking stops.
And doesnt come back even after driving for over an hour.
But if it alowed to cool to cold, then the leaking begins again on start up after 3-5 minutes..

No abnormal pressure in expansion bottle
oil and water look fine

ffs :)

Radiator tank seals can leak and then 'heal' when warmed up. As can the waterpump . Both parts are M3 specific and expensive :(
