Yes, the Foxwell did request all the registers reset to 0 as well and I confirmed but then when I went to modules/vtg codes it the oil wear code was there so I cleared it and rechecked it with 0 codes.

All normal then. :thumbup:

I had a look at an E83 recently that had a no-start fault. Fired up DIS and ran a scan - it had the oil wear code 54C6 - when I pointed it out to the owner, he looked at me like I had suddenly grown horns or something... I moved on to the no-start fault (was a dead starter motor). He sold the car a few weeks later and a week after that it blew the expansion tank and head gasket (chicken or egg?).

Meh.... :dunno:

When I was a the dealership picking up the Power Divider Oil, I stopped in at the service writers desk and asked them how much to reset the transfer case if I did the service myself and he said because I was such a good customer, he would do it for $95.

I bought the Foxwell NT-510 for $115 new off fleaBay so for $20 more, I now have the tool added to my diagnostics set of tools for future projects and diagnostics.

On a side note, the service writer told me they get $600 for the complete transfer case oil service. I'm into this for about an hour of work and $175 including the Power Divider Oil, drain and fill plug copper crush washers and Foxwell tool.

Guess that's why they're called stealerships. :rofl:

Usually the foxwell takes 1.5 uses to pay for itself. I paid almost $200 for mine and never felt for a second it was a bad deal.

I registered my unit with foxwelltech.com and ran a scan on update possibilities and it identified my unit as current firmware as of 10/2019. :thumbup:

I still have to do this. My unit is a year+ old and I've never checked for updates. :(. Thanks for the reminder. :thumbup:

I registered mine and it needed updates, which took years off my life because it was a PITA...

Did you not have a windows computer? I had to use a virtual machine on my Mac and still wasn't too difficult (other than the operator error) of missing the SD slot and dropped the micro SD into the empty body of the nt510 (fortunately it's screwed together so I could open it and extract the wayward SD)

This was a windows computer but the update would download but not stay so any subsequent check of updates showed only the previous version not the downloaded file. [emoji378][emoji95]

I just replaced the trans fluid and transfer case fluid.

From reading this thread, looks like I can't reset transfer case adaptations with INPA? That sucks, I'll try to figure it out with ISTA or DIS.

Now for the transmission, it seems pretty easy to reset adaptations with INPA. However in the article I found, it says a relearn procedure must be done following adaptations reset.
The procedure looks like a big headache

Granted they're talking about a different 6 speed transmission, but I wonder if anything like this is required for a5s 390r?
