hi All, has anyone used the fiatecuscan to bleed the bakes in the abs unit. i understand if you change the fluid and get air in abs, you can't just bleed it out, do you have to use FES some how ?
THANKS Paul

I haven't done it myself but I think it's obvious once you connect to the abs ecu. You activate the abs valves individually I believe to force the air out.

Hi phwspider, It all depends upon the ABS ECU in your car. If yoiu have Bosch 5.3 or later, (late Phase 1 and phase 2) you can use MultiECUscan. If you have the older Bosch 2Si ECU you will need to find a mechanic with "Examiner". This is the only scan tool that talks to the earlier 2Si units.

Had to do this myself a while back.

Good luck Mate.

I am afraid not. I tried everything over a period of two months. Pressure bleeding, conventional bleeding, vacuum bleeding, all to no avail.

When I pushed fluid backwards from the bleeder nipple, there was no obstruction as the resevoir filled up. It was acting like a one way valve.

In addition, with that circuit's bleeder open, the pedal was hard and could not be depressed.

Running the ABS pump and bleeding simultaneously is the only fix that I know of.

As long as you don't get air in the ABS pump, there is no problem. Just fit one new brake line at a time and bleed it through before moving onto the next. Easy, and no risk of air in the ABS pump.

Take the opportunity to renew all the brake fluid whilst you're about it as it is quite possible your brake fluid is original and way past its best.

PKR is right. No danger in changing your lines.

What caused my issue (hindsight is 20:20!) is pushing the caliper pistons back without loosening the bleeders. This causes the problem. If you are changing the pads, loosen the bleeders, retract the pistons and then bleed the system when finished.

I'm not sure I understand this, how does the air get in if you rewind the caliper with the bleed screws still tight, Surely the fluid just goes back into the resevoir. I can see that the ABS pumip
adds some complication but how/where is the air getting in at that point?

NOt undermining the OP just trying to learn.

Cheers

Anyone know exactly how to do this with Multiecuscan?
Something like activating the ABS pump while bleeding the brakes RR, RL, FR,FL. I'm pretty sure you can only activate the pump for 5-10secs at a time with MES?

Pleased i saw this thread, recently changed a rear brake hose and decided to change the brake fluid. The result is that i have ABS light on all the time. I have a P1 though so will have to visit a specialist. Im feeling better as i was starting to convince myself that id need a new abs unit.
