did you or they check under the back seat  ?  ...the rear heaters love to
leak.

1/2 pint in 200 miles isn't much.
makes one wonder if it isn't going out the tail pipe in such small amounts
there's no smell.

what does a pressure test reveal ?
it should hold say 12 psi,  from a pressure tester for an hour or more.

any chance that it's still getting air out a bit at a time ?
and that is the 'coolant' that needs to replaced .

Subject: Where's my coolant fluid going?

I recently had my 1.9 WBX replaced with a 2.1 - more power and it runs very
smooth - I like it. The problem is that about 1/2 pint of coolant seems to
disappear about every 200 miles. There's no sign of a leak, no odor of
coolant, no sign of it on the dip stick. The mechanic (reputable VW shop)
has been over it from top to bottom a couple of times with no luck. Does
anybody have any idea what's happening?
thanks,
