Hello Everybody,

Could you tell me how i should proceed on VCDS to bleed entierly the brake fluid on my Golf V ? (Clutch, ABS/ESP, Brake calipers)
  • What part of brake system must i bleed in the first time ?
  • What is the complete process to make the bleeding with success for all components ?

For ABS part: I know that there is an option in VCDS to bleed ABS but i don't know where it is ?

Could you give me your tips and tricks ? ;)

Look forward to hearing from you
Best regards

I think this module from Golf Mk5 does not have this functionality. I have came accross this problem a year or so ago.
Yet one local brake systems specialist suggesested a way to do this. Not sure if it works but net time I get Golf 5 (or similar to it car) I will try.

You can also engage ABS during a test drive a few times, and then do a round of regular bleeding with a vacuum
bleeder. The output test just engages the ABS unit to displace fluid from the valve block. When ABS intervenes during driving the same happens.

Hi. VCDS is not necessary to bleed entirely brake and clutch fluid on Golf Mk5.
You need only a 2 bar pressure bleeder.
VCDS is necessary only if you let air entering braking system, so if you have to bleed a car wich has actually his braking system full of fluid you don't need VCDS.

Bleed first each caliper in this official VW sequence:
-Front left
-Front right
-Rear left
-Rear right

Finally bleed clutch.

Hello everyone,

Sorry for the delay
I have the answer :)

ABS process bleeding module
Prerequisite :
-2 Mechanics
-A pressure bleeding machine with 1 litter of brake fluid minimum
-2 Bleeding bottles

Select 03-ABS-Break
Click on "04-Basic settings".
Select "Group 001" and press "GO".
Press down the brake pedal firmly as for emergency braking
The ABS pump then triggers itself.
Then connect the bleeding bottle to the front bleeding screws (front right / front left) and open them.
Then click on "next".
The ABS pump starts bleeding
Then press the brake pedal slightly 10 times (do not press the brake pedal all the way down to the floor to avoid damaging the master cylinder).
Close the two bleed screws (end of bleeding process)
Leave the process (Do not click on "next" otherwise the process restart)

After bleeding the ABS module, continue with a normal bleeding Front left / Front right / Rear left / Rear right -- Bleed approx. 200ml per breaking caliper.

I hope the procedure will help you.
Best regards

@PITCHY what pressure are you setting the pressure bleeder?

I had similar on 2007 A4 today. Never saw one of them before for bleeding. The ancient system with TRW cable operated parking brake rear calipers.
After messing around with pressure bleeding and wasting 30mins getting nowhere I ran the output tests (which indicate when to press and release brake pedal etc.) 3 times WITHOUT OPENING ANY BLEED NIPPLE

Then pressure bled ONCE (the wrong way apparently) as you do on BMW: LHR, RHR, LHF, RHF.
No air came from rear at all.
Substantial air came from both front bleed nipples (fluid for approx 6 seconds before air).

Closed everything off.

PERFECT PEDAL

====
Reason was customer had renewed both rear calipers but left rear calipers disconnected for 5 days. He had rear hoses kinked to stop fluid leak but air must have gone all the way up to the modulator.
It's interesting that normal bleeding bleeds the rear calipers completely and the modulator air exits through front calipers only. I'm guessing this is due to it being MK60 ESP FRONT system?
Anyway, it worked.
If I ever see one again I'll try the correct procedure.

Hello Everyone,

I've put 2bar or 30psi to bleed brake circuit.
It's the pressure preconised on the bleeder instruction for use.

Does this mean that bleeding the abs module is more for air trapped in the front rather than air in the rear ?

I have an issue where I keep seeing air bubbles coming from my rear calipers when bleeding at 20psi using a pressure bleeder but I see ZERO air bubbles or interruptions in flow when bleeding the fronts.

Would the abs bleed procedure be useless for me since my front calipers are not the ones in question ?

30 psi is the recommended pressure to bleed at ?

Hi

I’ve recently changed my rear callipers and bled the brake system. The pedal felt spongy so I replaced the brake master cylinder.I pressure bled the brake system and the brakes still feel spongy.
I ran the VCDS programme to bleed the ABS pump with a pressure bleeder. Still no change. I’ve gone through a gallon of brake fluid…
Any ideas?

If it is a Golf 5 you will need a pressure bleeder set at 1.5Bar max and VCDS to run the Basic Settings process. Before that you should do a basic pressure bleed and start at the master cylinder: how many bleed nipples on the MC? If you hadn't opened the circuit to change the MC you might have got away with it.

Thanks for your quick reply.
It’s a 2010 mk6 2.0l tdi
It has no bleed nipples on the master cylinder just 2 brake pipe fittings

Hi I’ll start from the beginning my GOLF GT140 TDI 2.0 2010 MK6
My brakes were excellent then they become less effective and I lost use of handbrake the guy at the garage freed off the hand brake for the MOT, shortly after the problem appeared again, he did say I would need to replace a rear calliper at some point.
I ordered a pair of rear callipers clamped the rear flex hoses fitted the callipers and bled the system the brakes were slightly better, handbrake worked but brake pedal was still low. I ordered a brake master cylinder seal kit upon removing my brake master cylinder it was apparent the seal kit sent was for a different brake master as mine doesn’t have a circlip. It turned out can’t get a kit for this master cylinder I even contacted ATE gave them the part numbers of the internal seals but they won’t sell them.
VW £310 for new master cylinder
So I bought a used one which I was assured was good this was an exact match ATE 23 the 23 is the diameter of the piston I may of been able to fit the ATE 22 but wanted to fit the correct item, so all fitted bled the system exactly the same low pedal.
I then read of possible issues with the abs retaining trapped air so borrowed a diagnostic tool and ran the vcds software bleeding the system. Still the same, repeated it a few times then tried again with the guy who owned the tool, still no joy.
I did hear of possible issues with some pattern new callipers having an internal leak so removed my new callipers refitted the old ones bled the system again. Still the same low pedal, so I refitted the new ones bled the system again.
I then removed the master cylinder I bought bench bled it and bench tested it, it was rock solid as I was concerned despite being told it was good I didn’t know for sure. I then went another step further and refitted it full of fluid after being bench bled by capping off the reservoir, bled the system again still the same. I checked my front discs & found them to be 1mm below the minimum so fitted new front discs and pads still no change.
I then bled the clutch also just to be sure still the same.
I have been using a pressure bleeder at 10 psi
I’ve bled just using the pressure bleeder draining off 250 mls from front callipers 300 mls from back callipers.
Also two man bleed had someone pump the pedal till firm then I open the bleed screw they press pedal down then I lock off the bleeder then repeat I tried raising a catch bottle high above the wheel arch in the hope any air will travel to the highest point still no joy.
I tried gravity bleeding it
I have now borrowed another scanner to activate the abs and tried again no luck.
I’ve bled in order of the furthest from master cylinder, I’ve also tried bleeding front left front right rear right rear left etc
I’ve tried bleeding both front at the same time
I’ve tried bleeding all four at once gravity style
This is really got me stuck now any ideas
All pipe work is not leaking flex hoses are not expanding
I’ve tried hose clamping off flex lines to take each calliper out of the equation
The booster isn’t leaking as when I removed the master cylinder for the second time I heard it hissing as pressure was escaping upon removing the brake master cylinder
No abs light is on, on the dash
The rear discs and pads were changed about 18 months ago
I just get clean fluid out during the bleeding without any air which is great but the pedal is still low if I press it once or twice more it becomes firm in a high position
I took it for an MOT to see if it would go through but it failed for brake pedal being low
Any help would be appreciated
It’s as if air is still in the system but I can’t seem to get any out

The RHD 23.8mm master cylinder 1J2 614 019 J REP is available from ATE in theory under their part number 24.4153-0202.3, it is just that they don't have any stock. I had this problem via another garage who were pulling their hair out over it and it turned out to be an internal fault in the servo
