Bleeding Brakes While Activating ABS Module with OBDEleven Tool - B7 Passat Flip Car
HTML-код
- Опубликовано: 10 сен 2024
- This is my last ditch attempt to resolve the soft brake pedal issue. I am bleeding the brakes in the recommended order, using an OBDeleven scan tool to activate the anti-lock brake pump. I am hoping to find some air trapped in the ABS pump / module.

Is that an industrial building size transformer in that battery charger? Damn thing sounds like it could power a train engine.
Lots of air in the lines got pushed out, great video!
Your battery voltage was dropping while doing this, Might be a good idea to turn of all heavy/unneeded electrical loads, especially headlights,👌👍
It's a good idea to keep the lights on when you're doing this sort of work. What happens if the power goes out? Then you'll be working in the dark.
@@bobdobbs7828 Ya cant teach stupid🤷♂️🤦♂️
@@campbell19872710 sure you can by questioning and acting like every answer given by a person is wrong even though it's completely and undisputubly true. It's how some very intelligent people raise their kids to be complete train wrecks.
Also, according to VW manual, VCDS or abs pump activation is not required. As long as minimum pressure of 2 bar or 29psi is met and maintained while bleeding with pressure bleeder all air will be purged from abs pump.
show me where it says that
@@Patrick-Mckinney oh do you not believe me ? I will gladly show you if you think your method is the only way
@@butters_ its the way the factory repair manual says
I know I’m 9months late to this comment, could you point me to where it says that? Manual, rosstech, even a forum from Audi users etc?
I’m hoping this is my issue as I’ve only bled with 15psi, would the reservoir handle 29/30psi of pressure?
07 s4 with 4.2. I’m assuming air is in the abs, we had the brake system open for a few Weeks while performing other services on the engine etc. I assume abs module went dry.
Anyones help would be cool, unable to get the abs module bleed process to work while using VCDS.
@@vicariousclouds2340 RUclips keep deleting my comments. Not allowed to post links or tell you where to look. However if search up online “Ross tech abs bleed 2 bar” it should be the 4th page down, click on that and scroll down to post #11
can confirm it works. I used 30psi on a previous VAG vehicle with new MK60 abs unit that I replaced to due common failing.
If all else fails try:
bleeding with engine on.
Lock the brake pedal down overnight a few nights with a piece of wood or whatever.
Activating abs on a loose surface a few times. Such as gravel or mud etc. Then try bleed again.
Also it should handle the pressure.
Does it bleed ALL individual ABS valves that seldom activate during normal drive? How to do it?
2011 Audi A4 ABS module has lost communication with the car. I have a used work in working order but it will need to be coded. The stock ones doesn't work and has my car in limp mode and disabled a ton of things. Sometimes you'll hear the stock one that's faulty clicking as if it's trying to work. Any ideas from anyone on what could be going on or can someone point me in the direction on how to code the new one so I can install it. Thanks in advance.
Looks like you have air coming in from the bleeder valve, might be why you keep getting air from that caliper
That’s what I was thinking originally but then wouldn’t you expect brake fluid to seep out considering the internal pressure of the fluid is greater than atmospheric pressure of the air?
@@ModernEngineer
Didn't know the OBD11 had this feature👍. 20psi is a little steep. Self bleeding brake flush machines tell you to never go over 16psi for any reason. Definitely seems like air is being introduced to the system somewhere.
Trying to do this on my 2014 Jetta. Did your OBDEleven require the security code entered first to do this in the brake module?
Did it help?
I had to fix a broken line and since then for me to get any brake I have to pump the pedal 3 times to feel the wheels locking in, I'm gonna attempt to do this over the weekend
Good video.. on the last few minutes of the video where there was a lot of air purging through the plastic hose on the waste bottle, was the abs pump running? All I can hear is your battery charger 60Hz humming.. I have same thing on my C5 Audi A6 Quattro it’s a squishy pedal but under normal tradition bleeding I don’t see any air in my hose on the bleeder screws regardless of what wheel I’m doing.. I’ve done buddy system ..open bleed, push and hold, tighten and release .. and I don’t see air.. I also used my Schwaben pressure canister system holding 15psig when opening bleed screws and didn’t get air, just clean brake fluid.. I have VCDS and will try this method with the pressure can on the master cylinder to bleed the ABS pump.. I did calipers and both rear hoses so I’m not sure if all the air is out.. maybe trapped in the abs pump? I noticed using OBDII I didn’t see you go into the car for anything so you don’t have to hold pedal or push it 10 times, which I’ve seen in other videos.. looking for some help to get brake pedal hard.. tx
I have a 2019 VW T-CROSS and has only 4000 km. Recently VW changed the brake fluid (time interval change) but after the service the cluth pedal is different. The clutch felt like a new car now it is more week like a used car around 40.000 km not a 4000 km one…. What happened? I am very dissapointed of VW service. Not to mention the quality - my car camed with missing screws and many more problems. Please reaspond 🙏 thank you! Great job with your videos. I do have obdeleven but still i have payd for theyr brake fluid change 😒 and i do not have your pressure tool.
How was the pedal after this air bleeding ?
After that , did the car brake as strong as a new brand car ?
Salute from France my friend.
Did this solve your issue? And is there a specific version of OBDeleven you need to perform the ABS bleed?
Did you figure this out?
@@StevenDanielZigila yes, I learned that is is possible through OBDeleven, per an email with them asking if this feature is available. I ended up investing in VCDS and I was able to replace my brake master cylinder and perform the bleed.
Do you have the standard or pro version of obd 11
Do you really need all this to do it?
Is this possible without that bleeder pump?
That’s what I need to know also!! Doing it myself
Will this work on a mk4?
How do you do this without the pressure bleeder? I have the computer… I’m doing this myself
The ABS Module will generate pressure, just make sure between activations of the ABS just go and top off the brake fluid again, don’t want air getting in to the master cylinder.
Please let us know how it came out I have the same issue with squishy pedal in my C7 Audi A6, I have the OBD eleven pro and wanted to do this procedure. Thanks for the videos !
I have the same car. I did it with normal procedures , first closest to driver side and last furthest. And after I bleed all four caliper and used obd11:
Control units >
Brakes>
Basic settings >
Bleed brakes>
And ran last option "finalize".
This helped on the spongy feeling..brakes feel better know
did it work? let us know !
Hello... passat b7 u.s styla sinyal parking can you make a coding video ?
Did you also bleed the master cylinder itself? Always thought that was necessary.
Can you use OBDeleven when performing a brake flush?Or is this only used when air is trapped in the system?
you can use it. I find the pressure bleeders like the motive work good though
That's WWWAAAYYY too much air
That's one loud ass battery charger.
