So I’ve noticed the rear tires seemed sometimes slow to engage immediately the last couple winters. I now have a code for open circuit in the haldex pump. Doing some reading online I see ECU’s are very prone to failing and can cause show as errors in the pump. The pump is cheaper and seems like the cause - what would you do? Is there more troubleshooting that can be done? Going through the output test with VCDS I get no current when activating the pump. I did replace the filter and oil at around 60k kms and we’re at about 101k right now.

Thanks,

Alright so Haldex works again. Stock pump tested at 80-90 kohms when it should apparently be 5-8 ohms. The new one measure at 10 but I won’t be that picky. I haven’t test driven it but I can easily hear and see it function with the VCDS output test.
