    No Haldex function

    I have a 2016 Yeti 4x4 which has no rear wheel drive at all. The Haldex doesn't engage, just front wheel spinning and traction control lights flash when it should be active. It's a Gen 5 Haldex, so no filter to block.

    There are no fault codes relevant to the Haldex unit, the pump is functional and clean, been bench tested with a battery pack and spins freely, I've exchanged the pump for a new one just to prove a point and situation remains the same.

    I've logged pump voltage, PWM, amps with vcds on a launch on gravel and there's no voltage increase at the pump when the front wheels spin, all I get is maximum voltage of about 3v DC which cleary isn't enough to activate the clutch pack. I also have a Tiguan (same year, same engine, same Haldex unit, part numbers, software etc.) and doing a launch on the same gravel surface in this gives a voltage spike to about 8.5v DC and the Haldex kicks in fine.

    It appears as though there's a lack of signal to the Haldex controller that the fronts are losing traction so it never calls for the rear Haldex pump to increase in speed.

    I also have graphs of Voltage, Amps, PWM of both vehicle launches for comparison, but the forum won't allow me to show them as embedded pics, so they're here

    Tiguan launch...

    http://www.viking-heating.co.uk/dama...n%20launch.jpg

    Yeti launch...

    http://www.viking-heating.co.uk/dama...i%20launch.jpg

    Any ideas where this would be faulting?

    Cheers.

    Strange fault. Did this car had an accident and was repaired before?

    Can you may copy here the Tiguan autoscan? Does it have the same AWD software version?

    There is a software update available for the AWD ecu.

    Yep, scan log from the Tiguan just now (ignore the Hvac fault).

    As far as I'm aware the car has not been accident damaged. It's clear on the HPI report at least.

    That's all via the powertrain CAN, and there's really only two places were it could come from, the ECU and/or the ABS.

    Both ECUs are coded for AWD, which is as it should be.

    However, I'm not sure about the MK60EC1 ABS in Yeti. Someone with better knowledge of that coding scheme than I have might check that for you, but I doubt it's there either, since I'd expect some sort of coding mismatch DTCs if the ABS didn't match the ECU.

    In the end, I'm not keen on the theory that the Hadlex isn't being told to do its job.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    So that would put it into the territory of the Haldex controller not doing as it's supposed to?

    I would say from your log pictures, the yeti also tries to engaging, only the signal amplitude is lower. So it's receiving the necessary data from the can network. It's unlikely the controller is bad, or anything coding related.

    I'm not familiar with these latest AWD system's,but it's possible the controller feedbacking from the wheel speed signals, what's happening while engaging rear drive, so if nothing happens, doesn't increase the engaging pressure.

    I heard some nasty things from late haldex units, which they had to replace under warranty with very low mileage. I don't know with what symptons, but they was internal mechanically damaged.

    Most Haldex failures have been due to there being no filter on the Gen 5 Hadex units I think. The pump clogs up rather than the filter, pump burns out, and so on.

    As regards the Haldex not getting feedback, it never gets enough voltage to engage the pump to lock the clutch pack so unlikely to be a feedback problem I think.

    Did you checked the power and ground on the haldex ecu connector? I mean the gnd wire resistant to chassis, power wire preferably under load.

    What the voltage , amperage, and pwm is measured at these channel you showing? Is it the pump current and voltage?

    Yes, those readings are all pump related.

    I've not checked any wires to the controller, they'reall as factory at the moment so sheathed.
