2015 Passat TDI polar FIS issues

[Bezra]

Hello, I have a pf04 installed in my 2015 Passat TDI SEL.

I took my car to the shop to have a timing belt changed. I asked them to go ahead and swap out the battery too while they had it. I turned the FIS off when I left the car at the shop. When they swapped the battery the FIS must've turned back on. The mechanic hooked up his obd2 scan tool to clear codes and a lot of the systems in the car started failing... Engine died, transmission stuck in gear, esc failure, steering wheel light, and many others...

He called me and I came to the shop. I realized the FIS was still on. I turned it off and some of the failures and dash lights stayed on. I then removed the FIS and the car worked normal and all codes cleared.

A few days later i refreshed the firmware and reinstalled. Car behaved normally but when I tried to go in and adjust visualization parameters I got the following message: Engine ECU not detected contact auto-ploar

I've reached out to auto-ploar and opened a ticket but I haven't heard back yet. Anyone have any ideas?

Thanks

almost sounds like the polarFIS died during battery connection? idk, perhaps the voltage spike or something got it

i think your best bet would be to wait and see what autopolar has to say

Took mine out and threw it away. To many problems.

Sent mine back after the car essentially shut off while pulling out from a stop sign (all lights on dashboard and i could only roll backwards in neutral) never heard from polarfis again (it’s been 2 years). Fun product but catastrophic failure is not good at all. I have a scangauge instead.

Hey, I also have a SG. Do you want some of the values for the passat that I've acquired. As long its a SG2 or SG3.

It’s a scangauge 2, that would be great.

I would grab the Engine Oil Temp from the 2015 passat and any other ones you want.
