Short questions are:
1. ABS not activating and there's no codes in lexia or dash warning after bleeding is it damaged?
2. Is there a speed limit for ABS - I tested on a steep slope at about 25 mph
3. Do I just need to repeat the Lexia ABS bleed process?
4. Is no comms with ESP the clue or red herring?
Background information:
Been working on a neglected 2008 207CC 1.6hdi VF3**************[VIN obfuscated, can be read by forum staff]
Brake fluid was critically low (pedal to the floor), STOP with
! Lamp and low fluid warning in Lexia - reservoir took about 400ml (after pads replaced).Replaced pads and bled manually = almost nothing.
Bled with pressure = bit better but not driveable.
Bled with vacuum, slow but mostly just pulled bubbles from the nipple thread.
Bled with vacuum directly from brake pipes = much better, can slow fairly well with spongy pedal but not sharp enough to emergency stop.
Back on lexia to bleed ABS. Global scan says can't identify or communicate with ecu (can't quite remember the message
). If I click on it I can choose 2 ecu's. First one has ABS in its name and the other has ESP. ESP has 'communication error' (although car has ESP button). Clicking ABS let's me check faults and Pack Repair let's me bleed brakes. I went through the whole process and while doing the 10 pedal depressions the pedal suddenly became much stiffer and I felt like I was on a winner (and pedal holds so looks like got away with not damaging master cylinder seals).
After completing the process I took the car on to a steep ramp into a local car park as its easy to initiate a skid under 25 mph. The brakes definitely work now.. The car locked up with a skid but no ABS. Also notibly the car did kick out despite travelling in straight line.
