PSM/ABS warnings on 996 Turbo

[Slobberchops]

I seem to have an intermittent PSM-ABS warning on my 996 Turbo, it has had fault codes for brake pedal switch and the abs pressure sensor, both of which have been replaced but it keeps coming back.

Usually the first journey it is ok, more often than not it is subsequent ones where it seems to come on again, and it may be coincidence but sometimes it is when the revs reach 1500-2000rpm but sometimes it just appears at random.

Any ideas chaps? The MAF seems to be clean, indeed I have cleaned it, and is not showing as a fault.

Had something similar happening to mine last year. Needed to replace the nearside front ABS sensor wiring loom.

The stock number for the bit was P996.612.957.00

I had this on mine - dying battery. Although the timing of the lights sounds a bit different to yours. Mine would come on within the first couple of minutes of a cold start then disappear.

Had this on a few cars now. ABS and stability/traction control seem to be power hungry, and trip into a warning mode if there is any chance that they won't be fully powered.

Had this a couple of times, again it was the wiring looms. NSF P996.612.957.00 and OSF P996.612.958.00. About £72 per loom and possibly 2 hours per loom to fit.
No more problems after having both done. Apparently this is a commom problem.
