Have been experiencing a grabbing sensation from the driveline when reversing or parking slowly on a steering lock. Read that it can be a symptom of haldex needing serviced. Last did mine 25000 miles ago so figured it was due. Removed the haldex today and was shocked to find minimal oil inside it. No obvious leak so suspected it had managed to find its way into the diff. I was changing the diff oil too and expected to find that it was over filled but I only managed to syphon out about 650 ml which is about what I'd expect. The oil must have gone somewhere but I'm baffled. Just hope I've caught it before the haldex cooked itself. No warnings about 'special progress unavailable' on the dash like I had last time when pump filter was partially blocked. Both refilled with the appropriate new oils. The diff oil (below) was pretty manky at 90000 miles old. I'll do the ptu tomorrow and that will be all the 10 year service items done at 8 years old.

If the the Haldex side of the diff seal has failed, the Haldex fluid will drip out the weep hole in the bottom of diff case. Haldex fluid is unlikely to get into the diff, as gravity ensures any fluid from either the Haldex or the diff drip out the weep hole, instead of contaminating the other fluid. Hyundai Ioniq 5 Ultimate.

Strange no sign of oil leaks underneath though? 🤔
I shall keep a close eye on the oil level.
