Intermediate ABS light after brake replacement

[aussieboxy]

Recently removed callipers for painting & upgraded the brake hoses to Stainless & slotted disks.

Flushed & bled the system & all good.

Since then the ABS light comes on/off intermittently. It will come on whilst driving & stay on for. Few minutes & goes off. It doesn’t seem to have any correlation to braking either slight or heavy.

Any suggestions would be appreciated

Cheers

When you removed the calipers, you let air into the ABS control system, which will not come out during a simple flush/bleed. To get it out, you need a Porsche specific scan system that can activate the ABS system while bleeding it. This is the only way to now get the air out. Durametric software, PST II or PIWIS will do the job.

Thanks for that. I have an enthusiast Durametric which has that faculty. Do I need to have the pressure bleeder connected whilst activating ?

It would be much easier and quicker to do it that way, just follow the sequence as the Durametric tells you and the air will come out.
