ESP 9.0i Basic Settings / Bleed ABS Module

Hello,

I would like to perform the ABS bleed procedure on a current Seat Ibiza Cupra (6P).
(Reason: The rear brake calipers were replaced, and after multiple bleeding procedures, the pedal is still very soft.)

I'm familiar with the process from the PQ24/34 platform (used in Golf4, Polo 6N, Fabia 6Y, etc.), where you need to go into the basic settings and then select channel 001 or 002 and follow the instructions.

The new Ibiza has a "Bleed brakes" option in the basic settings, but when you select it, an input field appears that requires you to enter values.
There is no help field available, so I am not aware of the value range.

Can someone explain the procedure for bleeding the ABS module using VCDS on the new MQB models?

Hi,

Please provide a Screenshot of the input field along with the rest of the screen.
(Press the Print Screen key -> paste into MSPaint or a similar program.) (Ctrl+V).

Best regards, Rainer.

Hello,

Attached are the screenshots.

Okay, thank you. And what happens if you press "Start" and nothing is entered, or if you enter "1"?

Best regards, Rainer.

Hello Rainer,

I plugged in VCDS again today and tried it out.
According to the help text, the "Data" field requires a value between 1 and 3. However, I then tried all the variations (1;2;3;001;002;etc.), and each time it resulted in the error "Message has an invalid length or invalid format."

I'm completely at a loss. From my current perspective, I will likely need to rely on a workshop with its VAS/ODIS system.

Hi,

"The help text states: 'The measured value must be 1 to 3 digits long.' A digit is a single number, so possible values would be 1, 01, or 001." Where 1 can be any digit from 0 to 9.

The codes you entered would have been promising, though. Let me see if there's anything new here.

Best regards, Rainer.
PS: I just noticed that you used a non-official version of VCDS in the automatic scan, which is not entirely up to date. Please install version 16.8.3 from your customer account, as it has a more recent data version. Okay, hier ist die Übersetzung des Textes ins Englische, unter Verwendung von amerikanischem Englisch:

Please provide the text you would like me to translate.

"You're right, Rainer, I completely missed the word 'stellig'."

Yes, I had also considered channels 001 and 002 and tried them, but unfortunately, I didn't have any success.

It's not a foreign language version in the strict sense. It's the German reference version directly from the Ross-Tech website. But I'd be happy to try it again using your version.

Best regards,
Robert.

No, that is NOT the Ross-Tech website... I recommend http://www.vcds.shop

Good morning.
I'm going to heat this up again .

Is there a solution yet?

A friend's Cupra 6P needs to have its brake system completely bled because the pedal feel is "soft," and VCDS/Cupra are failing us in the rain.

As described earlier in the thread, you click on "Start," and then VCDS immediately displays "completed."

There is no way to start the bleeding process, regardless of whether the engine is running or not.

Thank you.

I would perform a complete replacement of the brake fluid. After that, the problem should be resolved.

Hello Jochi,

What login code did you enter to start the ventilation?

The ventilation system in some vehicles only works after being unlocked or activated beforehand.

According to the manufacturer's instructions, a pressure of 2 bar should be maintained during the bleeding process. Increase the normal working pressure of the brake bleeder device to match the specified value.

If there is no venting device available and the ABS block has not been replaced, the two-person method should be used to improve pedal pressure.

Best regards,

Michael.

The login, where VCDS suggests it, was probably 10468.

But whether you're logged in or not, the default setting doesn't fail; instead, it immediately jumps to "completed" without any intermediate steps.

"This raises the question of what causes the "soft" pedal feel. Did it appear suddenly, or was there a repair performed beforehand?" Was the braking system opened?

For example, after installing refurbished or new brake calipers (caliper completely empty), the following scenario may occur:

If the vehicle was only raised on the side being worked on, an air pocket can form in the brake piston when the tandem master cylinder is installed. This air pocket may not be removed even after repeated bleeding, regardless of the method used.
It might help to gently tap the valve stem with a rubber mallet while bleeding the brakes, as this can sometimes help release trapped air.
If that's not enough, the saddle must be turned on its side while unmounted, secured with a suitable wooden block to prevent the piston from falling out, and then (pre-)bled.

It should display the message "Running".

Number plate, is 40168...

Best regards, Richard.

The braking system was opened, and steel bleed valves were installed on all brake calipers.

For filling and bleeding, we use a device from ATE, and not for the first time.

During the bleeding process, a large amount of air suddenly came out, even though the ATE device did not run dry or indicate a fault.

Therefore, a complete ventilation system flush should be started, but VCDS doesn't initiate it; instead of showing "running," it immediately goes to "completed," even when logged in with the code 40168.

Hello,

Years ago, I had a case of a corroded sealing ring between the brake hose and the brake cylinder on the rear.

He occasionally bled air from the system, but it was not possible to permanently remove all the air.

After applying firm pressure to the brake, it then became completely leaky, and the fluid started pouring out from the back of the wheel.

Best regards, Rainer.

Putting aside mechanical problems or leaks, isn't it also abnormal that VCDS doesn't control the ABS pump or that the pump doesn't respond?
