Clutch hydraulics, weird 4kq clutch

[John Larson <jdlarson@ix.netcom.com>]

Porsche, VW, and BMW use the same hydraulic setup, common reservoirs.
Annual flushing of the systems help prevent premature hydraulic
failures. We prefer DOT 4 fluid, and use it in all the cars we
service.Cars with ABS require even more care of the system, as their
components are REALLY expensive to replace. I would suggest a good 1 to
2 litre bleeding/flushing, and the replacement of both the clutch master
and slave cylinders. This is a common problem, and experience tells me
that you'll need the other soon after the first one. Good luck.
