Check for vacuum leak first. Most likely cause.
You can also run a throttle body adaption (with VAGcom).

You probably have a vacuum leak somewhere. Check for broken or cracked hoses and/or plastic pieces they connect to. Pay special attention to suction pump, part# 058 133 753 B. Google it.

have you checked the brake lights for operation ?
if they don't work than it is your brake light switch located on the pedal support bracket.
