: 1998 s3 performance issues

over the past few weeks i have noticed a reduction in power with my s3. in lower gears it doesnt seem to have the torque or acceleration like it used to. when in higher gears traveling about 50-60mph and i accelerate the rev seem to drop slightly at 3500rpm then pick up again but there is no obvious boost in power when the turbo kicks in.

could it be a problem with the turbo? what are the tell tale signs that a turbo is on its last legs?

I would check for air leaks or even swap out your DV but before spending money check also the sparkplugs.
