Passat 3B ABS FS reading not possible!

Vehicle: VW Passat Variant V6 Syncro 2.5TDi AFB, 2000 with Bosch ABS/ABD 5.3 (or similar). ESP).

"On the vehicle in question, the ABS fault memory can no longer be read. Three weeks ago, it was still possible (the combination instrument circuit board was identified as the source of the error). Reading is not possible with any of the following devices: Bosch KTS 520, VAG 1551, VAS 5051, and VAS 5052. All other control units are functioning correctly." The power supply at the STG connector (KL 30, pins 17+18, KL15, pin 15, and ground, pins 16 and 19) is ensured.

Is it possible that reading the error memory will not work if the circuit board in the control panel housing or the combination instrument is defective?

After turning on the ignition, a warning sound is heard, and the MFA (Multi Function Display) shows: "Stop - Brake Error - Consult the owner's manual."

Have you ever experienced this?

Good morning.


I'm experiencing the same problem with a customer's vehicle, a Passat Variant 3B with the ACK Synchro engine.
98 model year, without ESP, Bosch 5.3.
Occasionally, there is also no communication with the engine control unit (ECU) or the ABS control unit.
A control panel module was replaced as a test, but it didn't resolve the issue.
The power supply is working correctly, and the mass points have been checked and are okay. I have ordered a new ABS control unit.
Are you already one step further?
Best regards, Walker Patrick.

No, I don't currently have the customer's vehicle in my possession, but I will also order an ABS control unit first.

No - I currently do not have the customer's vehicle in progress, but I will also order an ABS control unit first.

I will be replacing and coding the ABS control unit next Tuesday and will keep you updated. What is your name and where are you from?
Greetings from URi, Switzerland Walker, Patrick.
Have a nice weekend, I wish you all the best.

My name is Bernd.

Waldraff-Automobile.deHello Bernd

I hope you are doing well! I was able to try replacing the control unit, and it worked. Unfortunately, the OCC control unit had a mechanical damage from being transported.
What is the approximate cost of an ABS control unit or ABS module?
Can you help me with this? If so, could you also provide the VW original part number or the Bosch part number, if possible?

If Bosch could supply it, the engine control unit with hydraulic block would cost us 570 EUR plus 16% VAT in our workshop's purchase price. However, they have a minimum lead time of 8 weeks from the date of order. VW part number for my ABS: 8E0 614 111E.

Good morning, Bernd.
Thank you for the information. 'I have a question: Is it possible to order just the control unit without the hydraulic block? We are in Switzerland, and while it's possible, it costs too much in my opinion.'
My ABS unit has the VW part number 8E0614111a or the Bosch number 0265220408.

I wish you a lovely weekend. Best regards from Uri. Thank you very much, Patrick.

No, in Germany, we only order the complete unit (hydraulic block including...). (Control unit) is possible.

After replacing the hydraulic unit with the control system, the system is working again.

Thank you, Autofitti, for the feedback.

It's good when questions don't remain unanswered, but rather when you know how someone solved the problem.
