I think with a Durametric/Hammer/T OBD thing...
should pop a fault...

JPS

Mine came on once with low fluid. Topped it off and nothing since.

I think this problem has to do with fluid being low or dirty, I know than on C4 or 4s the light stays on for 15 seconds, but on my C4 I had to step on the acceleratior and to get the RPM til about 5000 and than the light would go off, but after I bleed the brakes the light would not stayed on anymore...

Got back the car from paint shop and has the antilock orange light on dashboard.
it stays on even if I restart the car.
also the speedometer tachometer (speed gauge) doesn’t work.
May it be connected?

Most likely candidates are the brake pad wear sensors - if the circuit is broken the light will come on so possibly intermittent

or the handbrake switch at the base of the handbrake. The contact comes loose and starts with intermittent warning light as described.

both are simple if not quick fixes

Replace the abs relays in the frunk right side of car under cover against the spare tire. Report back if your issue persists.

I did replace the relays and the intermittent abs light is gone.

Fede-993

planning to purchase them today.
question: how many relays have tj be changed in that “impossible to open box”
I found one in pelican parts

I bought them from an ebay seller (https://www.ebay.com/usr/partscontainer).

One of this (https://www.ebay.com/itm/Rear-Multi-...oAAOSwtJZXWUun)
Two of these (https://www.ebay.com/itm/For-Porsche...IAAOxyT7NR5~Lu)

The plastic cover was a real pain to remove but I was able to take it off without "breaking" it. It has channels on each side, and you have to slide the cover upward as far as possible and wiggle it out from one side, and the other side will pop out. The cover was quite flexible.

Wherever we go, there we are.. lol.

My Anti Lock brake light came on again. Funny thing is, I never did anything to correct it in 2012. It just went off.
I did a quick test though and stood on the brakes and they locked up.. Didn't feel any ABS.

Check your fuses under the frunk - could be one of them.
