Do these units have a K-line connection or only CAN?
If you can enumerate them using VAG-COM or something to find their KWP1281 or KWP2000 address, it wouldn't be very hard to try to talk to them.

Dont be so sure about that.. the blue controller consists also of an "upgraded valve-package" according to the haldex people themselves here in sweden..
O.k., thanks for clarifying that. TTQS |

Do you know what protocols you can connect with? Is this just using VAG-COM and the KWP1281 protocol? Do you know what address you are connecting to? (VAG-COM lists the address) Is this on Gen1 or Gen2? PS: I know nothing about Haldex controllers.... |

Gen1 has K-line and CAN, Gen2 and above have CAN only. Address is the same 22.

Per the pictures on the first page there is nothing other than a controller board inside the stock unit. So if they are doing hard work to the valves I would imagine its not so plug and play. I love this thread but most of it is way above me. |

Just figure out the CPU and then just perform boot mode, if possible.

Gen2 boot mode is easy, in Gen1 not so easy. I'm working on OBD-solution, because opening the controller requires too much work. Not very practical to do in the parking lot.
Gen2 responds to addresses $0A (TP2.0) and $1C (KWP2000). VCDS connects with CAN-protocol TP1.6.

Could we just by pass the haldex controller and can-bus systems and drive the pump ?
I was thinking of using the output from the boost gauge and having it engage the rear end when in boost.
This would be a really basic modification as I am pondering running the system in a Mk2 Gti and dont want to carry over the ABS and all the electronics needed to run the can-bus.
T2 - Socket between control unit and feeder pump(pwm switched voltage)
T2/1, Yellow = Pump 1
T2/2, Yellow/Black = Pump 2
I am thinking of just driving those.

That only provides 'priming' pressure, it does not engage the clutch.
Control valve is driven by a stepper motor, so you would also need to adjust it's position.
Alternatively you could make hardware modifications and adjust clutch pressure manually, but that is not very wise.
As stated before, there are aftermarket solutions for controlling without can-bus.

There is for sure but they are all to the tune of $800+ I just think that's ludicrous, I can get a ECU tune for $650 and that is alot more complex. I was hoping there could be some good ideas generated here, I think there have been. Just need to take the next step. |

Agreed. I'm EXTREMELY interested in all of this but it's all above my head like stated above. Any progress on this?? |
