As I'm currently isolating I decided a Haldex oil change was probably overdue, and I had no excuses. 2016 Scout 60k miles, with Gen 5 haldex. I always change my own engine oil and filters, but unless I had found the info on here , I wouldn't have known of the Haldex oil and filter issues. I do use my Scout on gravel roads, grass and snow, so I knew the system was working, but didn't want a needless breakdown.

I ordered the kit from haldexrepairs.co.uk, and at £46.30 inc delivery I think thats good. All you need, including syringe. I used ramps and found access easy. The guides on here and a couple of Youtube vids (search for vw alltrack gives good USA vids) showed me the way. If you can change engine oil, then Haldex oil is well within a DIY job, only needs a few hex and torx keys, plus ice cream tub. I removed the control unit to give me enough slack cable to remove pump, as getting fat fingers to the connection was impossible. My filter was truly clogged up, with fibrous gunk. Cleaned, and refitted with new seals. Refilling is easy with syringe. A quick prime of the pump, a run round car park in 4x4 mode, top up again, and its done. The oil in the kit is just enough to do the job. I will change it again in 20k miles and see if there is a difference then. Thanks again to the people on here for their good work. Saved me other garage bill!

I saw the job being done on an Audi TT with a problem, by Andrew from Volkswizard on his YouTube channel. Seems the instructions are very comprehensive from Haldexrepairs.co.uk
