Wiring installation

Not all cars are listed.

If you car is not listed feel free to ask if its compatible.

CAN Convertor to analog RPM signal For ECU's without RPM output this will convert the CAN bus signal to a 12v RPM signal.

Also for ECU's that have a 5v RPM output that cannot be used on a 12v Tacho.

All VAG CAN cars

Gen I
Ab 1998
Hydraulische Ringkolben Differential Pumpe (Drehzahldifferenz HA / VA)
Lamellen Ölkupplung
Elektrisch kontrolliertes Druckventil
Regelelektronik.
Vorladepumpe, elektrisch, um etwas Vordruck aufzubauen.
´Der Filterdeckel ist kuppelförmig, aus Nylon und mit einem Spezialschlüssel Gr. 48 / 12 Zahn zu entfernen.

Gen II
Ab 2002.
Hydraulische Ringkolben Differential Pumpe (Drehzahldifferenz HA / VA)
Lamellen Ölkupplung
*Regelkreis mit Drucksensor und elektrisch kontrolliertem Druckventil.
Regelelektronik.
Von außen gesehen:
Bei Gen I war das Differential noch völlig separat und einfach an die Haldexkupplung angeflanscht.
Der Filterdeckel ist flach, rund, aus Metall und mit einer normalen Nuss (Gr. 23/24 ?) zu entfernen.
Der Filter selbst unterscheidet sich etwas von Gen I.

Gen III
Ab 2004.
In VAG Fahrzeugen wurde keine Gen III im eigentlichen Sinn verbaut.
Das war den Volvo und Opel Fahrzeugen vorbehalten.
Für VAG Fahrzeuge erfolgten aber Änderungen in der Software der ECU und Bauteile der Gen II wurden minimal geändert.
Daher wird hier oft auch mal von Gen III gesprochen. (Ist es aber nicht)
Gehäuse, Lamellenpack, Filter, Filterdeckel und Öl ist ist also identisch mit Gen II.
Erstmals wurde hier auch ein optionales quer sperrendes Differential eingesetzt, das von der Haldex ECU angesteuert wird.
(Sportdifferential)


Gen IV
Ab 2008 (Modeljahr 2009!)
*Die Druckregelung wurde geändert. Dazu wurde das Regelventil geändert und es fielen interne Ventile weg.
*Keine Ringkolbenpumpen mehr. Die elektrische Pumpe sorgt für den gesamten Systemdruck.
*Das System wurde noch schneller und wird über den CAN Bus in die Fahrdynamik einbezogen.
Von außen gesehen:
Bei der Gen IV sieht das ganze aus wie ein großer Block.
Filterdeckel und Filter siehe oben im Bild.
Der neue Filter ist wesentlich größer.
(optionales Sportdiff. möglich)

Gen V
Ab 2012 (MQB Plattform)
Die Druckregelung wurde völlig geändert und hat nun einen Zentrifugal Druckregler.
Dabei wurde die Anfälligkeit mit dem Einsatz von weniger Teilen reduziert.
*Wegfall von Akkumulator und Regelventil.
*Druckgenerierung nur durch die Hydraulikpumpe.

How to install the Haldex Controller:

Standalone

Inline

The Haldex Controller for inline use is designed to be plug and play.
It will be placed between the original wiring to the haldex with original connectors.

Haldex Controller Main screen

Lock Mode

The Haldex power is set by a fixed value that the user sets with the App
Can be adjusted in steps of 10%
100 / 0
90 / 10
80 / 20
70 / 30
60 / 40
50 / 50

100 / 0 is 0% to the haldex unit but the pre charge pump is still active for Gen1 and Gen2

Throttle Mode

The Haldex power is set by the configured value at a certain throttle position.
Throttle position in steps of 10%
0 – 10% 50 / 50
10 – 20% 60 / 40
20 – 30% 50 / 40

Speed Mode

The Haldex power is set by the configured value at a certain velocity.
Speed in steps of 20 km/h
0 – 20 km/h 50 / 50
20 – 40 km/h 60 / 40
40 – 60 km/h 50 / 40

Boost Mode

The Haldex power is set by the configured value at a certain boost pressure.
Boost in steps of 100 mBar
0 – 100 mBar 50 / 50
20 – 40 mBar 60 / 40
40 – 60 mBar  50 / 40

Passthru Mode

All signals from the car are passed thru to the Haldex so it will function like original.
The display will shows the current Haldex power.

Off

The Haldex unit is completely off including the pre charge pump.
The car will drive like any normal 2WD car.

Haldex status -- / --
This will show the actual status of the haldex clutch, front wheels / rear wheels.
Since the front wheel are always connected max power to the rear wheel can be 50% 50/50.

Settings button to the corresponding Mode settings.
Brake ignore settings (only visible when activated in settings menu).

Error Icon
When active you can tap the icon to show the error.
No connection to Haldex - problem with communication to haldex
