Good afternoon all Recently changed my leon cupra and bought an S3 210 however im having issues with the CTS and thermostat which I know has been covered lots. New CTS and no difference so a friend has plugged and its showing fault code p1772 which I cant seem to find a description of. New thermostat may be needed as its rough idle, loss of power (no boost) over 2500 revs and the temp needle wont really go over 60. Anyone who can help explain the code p1772?? Many thanks.
