    2.0 16v 9A ECU vacuum

    Hi guys,

    I have a newbie question

    Does the corrado 2.0 16v 9A has a ecu vacuum line?

    I have some idle problems, cleaned the ISV, and after looking thru the forum I saw that the ecu vacuum line for G60 and VR6 is sometimes the issue.

    I looked at my ECU and I just don't seem to find one.

    Thank's for the support!

    So... this is what the back of my ECU looks
    Should I plug the ECU vacuum in this hole?
    Is it supposed to have a plug of some sort?

    Hello there,

    I don't think the 2.0 16v has a vacuum hose going to the ECU, the G60 has so the ECU can measure the vacuum advance or the boost.
    But like I say the 1.8 16v and 2.0 16v Corrado's don't normally have a vacuum hose to the ECU.

    There sometimes is a black or green plastic/rubber bung / plug,
    in the back of the ECU but not always,
    i.e to seal the hole you are showing in your photo.

    Had MK2 1.8 Scirocco Scarla 1998 to 2002
    had it lowered on original wheels,
    K&N air fitler and Janspeed exhaust system.

    Now have 94 M reg Corrado 2.0 16v since 2002 still got it, been off the road now since early 2015
    hoping to get it finished this year.

    Also have a 2015 Seat Ibiza TSI i-tech as my daily driver. Plus I'm on The SEAT Forum.

    Link to 16v torque settings & ECU pin locations.
