    Hi all,

    Might be a stupid question but just got my '99 S3 and when i turn it off and it's hot I can hear liquid running near the front of the bonnet. Could this be some sort of after run pump, I'm not yet familiar with the S3 motor so this is probably a noob quesiton.

    Cheers

    Yes... S3's have an after run pump thats runs for around 10mins after the engine is turned off

    What purpose does the after run pump serve exactly?

    Keeps coolant circulating around the turbo to preserve it's life.
