Technical Documentation Teves MK20

Hi,

Upon closer inspection of the braking system on the rear axle, I recently noticed that my 1996 Volkswagen Golf 3 no longer has a brake force distribution system.
I knew that this wouldn't simply disappear during product development without being replaced in some form or another.
So, after doing a little searching on the internet, I found some scarce information suggesting that my Golf 3 is likely equipped with a Teves Mark 20 system.
In the 'Problem and Solution' section, Michael II posted various error codes and setup instructions today. From this, it could be inferred that this system includes sensors for measuring acceleration in both the lateral and longitudinal directions.
That has led to the explanation for the 'missing' brake force distribution system.
Now, I'd really like to know exactly how the whole system works.
Unfortunately, I haven't found much information about it online so far. Even on the Conti-Teves homepage, there is nothing to be found besides a sales description.
Does anyone here happen to have a technical document or at least a functional description of the Teves Mark 20?

Hello,

Not all vehicles are equipped with all sensors. Depending on the equipment, different configurations are possible (e.g., ESP may include a steering angle sensor and a yaw rate sensor).

Regarding the brake force distribution system:
This is replaced by an electronic system (keyword EBV: Electronic Brakeforce Distribution). For this purpose, the system utilizes the rear ABS sensors.

Regarding the basic settings: (this generally applies to all control units).
The individual channels should only be adjusted by people with the appropriate experience, for example, to perform a zero-calibration or deactivation.

Hi,
So, it seems that with EBV (Electronic Brake System), it's now possible, thanks to faster processors, to slow down the wheels in the slip area. A traditional form of 'stutter braking' is likely unsuitable for controlling braking force at the rear.
And what about the sensors for longitudinal and transverse acceleration? Are these sensors only used for the ESP system, or are they also used for the EBV system?

I upgraded the MK20 system from a G3 model year 1996 to my G3 model year 1994, and I didn't need any additional sensors. The G3 only has acceleration sensors for the side airbags. As mentioned before, the brake force distribution is controlled electronically. I don't know exactly how it works yet, but it works very well.

Sensors for lateral and longitudinal acceleration are only required for the ESP (Electronic Stability Program). Unfortunately, that wasn't available in the G3.


Quick question!!

What is the difference between EDS and ASR in Volkswagen vehicles?

Hello,

The sensors for longitudinal acceleration are only available in all-wheel drive vehicles.
The ABS system detects, through the wheel speed sensors, when a wheel is about to lock up and then reduces the braking force.

It's funny! I keep hearing about the longitudinal acceleration sensor and all-wheel drive. I have a TDI PD engine (ATD) at home. It comes with the transmission and axles. It's brand new, manufactured in August 2001. It's WITHOUT all-wheel drive and WITH a longitudinal acceleration sensor on the corresponding steering column. According to the SSP ESP documentation, Michael is right. What I have here is from July 1998. It's possible that this has been changed in newer Golf models.

Hello,

EDS = Electronic Differential Lock.
Up to a speed of approximately 40 km/h, the drive wheels, which are prone to spinning, are braked via a brake intervention system.

ASR = Anti-Slip Regulation.
This specifically reduces engine power. ASR functions across the entire speed range.
