Auto-Polar FIS+ Advanced - Complete Guide

remove the fuse. had a similar issue last weekend.

Three ways to reset the FIS+:

1. Pull the connector off the FIS+ module and reconnect
2. Pull the fuse (F24) from under the hood
3. Disconnect the battery

I do the first as I have easy access to the module/connector.

If you ever have the problem where your radio does not switch off when you remove your key then you know that the FIS+ firmware has crashed.

If this ever happens, please make sure you reset the FIS+ and ensure radio powers off before leaving your vehicle as otherwise you may well come back to a flat battery.

Generally the later firmware versions are more stable (i.e. known bugs have been fixed). Though I am aware that some BT units can send commands/characters which upset the FIS+ (certainly used to be the case at least).

I removed the battery. that way, everything gets a reboot.

Dam - I didn't think about a power off reset - I just removed it from the car

Live and learn I guess

also might be worth performing a reset. not factory reset, but the user settings reset thing.

TURBO PRESSURE parameter (extend info)

<snip>

These are available options in the pressure configution menu:

- AUTOMATIC : PolarFIS will select the best option for your vehicle automatically. RECOMMENDED !! (by default)
- INFORT X1 : To obtain the turbo pressure from the infortainment bus.
- INFORT X2 : To obtain the turbo pressure from the infortainment bus. The reading is multiplied by 2 (only vehicles in which the bus only shows half pressure).
- DIAGNOSIS : To obtain the turbo pressure from the diagnostics bus, for vehicles that the other options don't work.

I've observed in my Mk6 GTI that I need to use the Diagnostics bus option in order to get a valid boost reading. Unfortunately, however, this setting only affects actual boost pressure, and not requested pressure (which, presumably, is not available on that bus). Has anyone else noticed this? Pity, as requested boost would be interesting to see if it could be displayed accurately.

I'd also be interested to hear which parameters others feel are useful to them? I'm glad I've now got a reading of intake and exhaust temps, although I'm not yet sure what constitutes "too hot" for each. Seeing over 750 degree exhaust temps on moderate throttle up hills was an eye opener...

I don't know if I have a faulty unit or I'm doing something wrong.

I installed everything over the weekend, reconnect battery got esp fault as expected.
I can get to the phone screen which is now the polar fis screen and can press up/down to show different parameter screens but that's it.
Can't work out how to go to polar main menu to customize the parameters or access chronometer etc.
what do u press?
Ok does nothing and back jumps to the mfd screen.

And my footwell LEDs have stopped working with ignition on. Only work with key out doors open.

Press and hold the OK button to get into menus.

The footwell lights is a comfort setting so possibly this would have gone to the default setting in the FIS+.
