I have a ABC Visit workshop white indicator. After the car warms up, the ABC goes away but then I get this big puddle of fluid?





Where is the leak? What should I be doing next? I haven't driven the car.

You might want to look around the pump and reservoir area to see if something is obviously leaking in the area behind the LH headlamp. Be sure that you do not run the engine unless the reservoir has fluid in it otherwise you will ruin a very expensive pump!

One of your accumulators are bad.

You haven't filled-out your profile or otherwise indicated the year of your car, so I don't know what version of ABC your vehicle has. At any rate, I would jack-up the vehicle and remove the left-front tire. Then I would remove the plastic fender liner, as this should plainly reveal the source of the leak.

Best guess: you have an early ABC system and the leak is coming from the pressure supply valve block.

Thanks for the suggestions guys.. I have a 2005

You have an early system. You may simply need to unscrew the pressure sensor (B4/5, photo) and replace a $2 o-ring or loosen and re-tighten one of the lines which connect to the block.

Thanks Rod, I will find some time to jack up the car and check it. If that's where it's leaking, where do I get the O-ring? Is it a dealer item?

You could get the o-ring from the dealer. Incredibly, it comes with an installation tool which you don't need and costs around $70.

If you existing o-ring is bad, then I would simply take it to a hardware or auto parts store and find a $1 replacement which matches it.
