So the Haldex service is due every 30k or 3 years from my understanding. The 2015 I just bought only had 14k miles but was past the 3 year mark so I drained the Haldex fluid and was surprised by the amount of gunk behind the pump inside the pump housing. The contamination looked grainy and clumpy up but the consistency was like that of applesauce, it was all soft and pliable.
Thankfully there was virtually none inside the screen when I popped it of so it seems to be doing its job.
When I pulled the ridiculously long drain bolt there was also a gob of similar contamination that popped out when it first started draining. This car has the United Motorsports Haldex tune so it most likely has a higher duty cycle than that of a stock Haldex. From what I have seen this is rather common, I can see why failing to clean this out can starve the pump and cause a failure. Thankfully this pump is so easy to access!
