    On my E61 I have just noticed that the engine undertray is damp with oil or other fluid just on the drivers half. The staining is most at the front under the radiator or aircon rad but no loss of cooling fluid and the aircon is ok. Has anybody got any ideas please.
    There are no obvious drips and nothing is dripping off the undertray but need to sort before it gets worse.

    Thanks

    the air con can leave a puddle of water under the car when you have been using it on hot days so if it is water its ok

    my 525 did this, it was the pipes that connect to the intercooler.

    the seals had deteriorated and oil was seeping out.

    enough to leave a 4" diameter oil stain on the driveway.

    i replaced the seals (5 each or so) and not it no longer seeps, out but it is still showing evidenc eof letting a little oil past but not enough to mark the drive way etc

    the seals are item number 8 in this diagram

    Thanks for that. I have just checked the intercooler inlet pipe and it is a bit damp so I will have to find time to get it done. Not leaking on the drive yet.
