as per this topic http://www.golfgtiforum.co.uk/index.php?topic=118132.0, MaxxeH has noticed my vac is a bit low on tickover...

What is everyone's reading on their 1.8T at idle?

well I've just taken it out and it seems to be running -19 on tickover so it doesn't look like it's a problem

mine runs between -18 and -20 depending.
