Default ABS-ESP Bleeding issue

Replaced discs and pads all round, and checked over all sliders on the callipers.
Had to remove a couple of callipers to do the job right, and the fluid emptied.

Wasn't that worried about bleeding the ABS unit as i have just bought Lexia 3 kit from easy diagnostics. Sure enough, system wouldn't bleed the conventional way, so plugged PP2000 in. But I cannot get it to recognise the ABS/ESP unit. Under replacement parts, it lists “ABS 5.3 BOSCH” and “ABS8 BOSCH”. When quering the ECU’s, ABS 5.3 BOSCH returns “THE ECU HAS NOT REPLIED” and ABS8 BOSCH returns “PP2000 UNKNOWN REFERENCE, ECU BEING REFERENCED”.

It attempts to carry on with the bleeding sequence, after the above warnings, but stops at the first attempt, stating “no communication”. You can hear it running the pump, but then stops.
The system was fine, no braking or ABS/ESP issues before fluid change
I have emailed easy diagnostics helpline, and am waiting their reply.

Any ideas, or how to do it without PP2000?
Thanks, Mike

As the pump is not dry like a new unit you should be able to bleed normally. If you still have a soft pedal find a gravel side road or similar loose surface and with no other cars around stamp on the brakes to trigger ABS and cycle valves then re-bled brakes

Un-drivable with the brakes at the moment as no pedal pressure at all.

Just found this on Planet Peugeot, "URGENT : Bleeding must be carried out with the vehicle on its four wheels (circulation of the brake fluid in the compensator) "
I have mine on axle stands, could this be the problem?

Doubt it you should still be able to get a pedal

It may have been easier just to clamp the hoses to avoid loosing all the fluid

Even if the pressure is being stopped at the rear the front should still build some pressure manually bleeding giving you a soft pedal not nothing.

Servicebox doesn't show a compensator for my car.

I am going to take a chance and try and drive it, and activate the ABS.

hope you've got it sorted now.it appears an airlock happens in the abs unit. I had the same issue with not finding the abs unit. what car are you using and do you know engine code etc. mines an early 307 SW and appears to have an engine used in the 406.....

Default EasyDiagnostics Fixed the Problem

Hi Guys

Just a quick message to clear some confusion up. Spoke to member today and arranged a teamviewer session.

Problem = No comms on ABS and wouldn't allow auto bleeding....
ECU is being referenced please contact technical

Just typical French software being stupid. The members car had 3 abs possibilities, and was just a case of selecting correct typy (BOSCH).

Done a diagnostic anyway to show in action, cleared a fair few faults, and
also advised a replacement part to completely clear all faults.
This is why we are a little extra compared to cheap Chinese crap

SUPPORT, REMOTE DIAGNOSTICS, TEAMVIEWER SETUP, PLUS MORE

just thought I would like to clear this thread up.

Jim

Jim, do you mean that on PP2000 you can select the correct ECU for the abs system or are you using different software?
