I had the pleasure of driving down and meeting Paul this morning. He preformed a Brake/Clutch, Slave/ABS/ABD system bleed on my cab. No doubt this is some good preventive maintenance.
Many thanks Paul.

Al,
Again you have proven positive that a picture is worth a thousand words! Those waxy clumps can't possibly do any good within a braking/hydraulic system...
I have read that DOT 3 brake fluid, will dissolve the wax within a period of (unknown) time... I also read that rubbing alcohol will dissolve the wax immediately, and the system should be flushed with alcohol.
Personally, I would refute flushing a hydraulic system with an alcohol that contains so much water (30%)! Not a good idea when refilling the system with a hydroscopic fluid.

Does the PIWIS activate the ABS in the same way as it works when you excessively brake?
if it does then no need to buy the tool, just take the car round the back and do an emergency stop or two
or go AX

Chuck, it was a pleasure meeting you this morning and that gorgeous cab with the cedar green leather interior!

No, it cycles the ABS ABD systems but I have heard of others actuating their ABS ABD systems with hard braking. If you're going to do this, I would recommend doing so in the wet or on snow, so as to not flat spot a set of good tires. If you're going to replace the tires anyway, it doesn't matter...
Presumably this ABS ABD system cycling can't be done with the Durametric tool?

... along with codes that get reported by the durametric tool, for which there is no cause or trouble code.
I have a durametric tool that I used until I bought my Porsche specific, PIWIS.

People have suggested that DOT 3, DOT 4, alcohol or heat may dissolve the wax. Has anyone taken a sample of the wax and verified any of these?
Will alcohol harm anything in the brake system?
Apparently the summary of brake bleeding is that you can either find someone else with a tool to exercise the ABS or buy one. The UDT999 is the lowest cost.
