Firmware update area HowTo upgrade (Video)

In the case you desire to update your PolarFIS device already plugged in your vehicle, before you must to put your unit in flash mode. Here will explain 3 methods for do it :

Method 1)

Method 2)
– Extract fuse F12 or F24 (5A value) from your vehicle.

Method 3)
– Connect PolarFIS via USB to your computer.

PolarFIS not detected, What must I do?

First of all, please verify all this points, for check if you are doing properly.

  • Verify your type of cluster (color) and firmware
  • Verify if all connectors are properly pluged
  • Check that you not have nothing plugged in your OBD port
  • Check that your box is not connected to any computer via USB

If you already checked all this, and your PolarFIS device still not working, please contact with our support team at, and place there your problem with exhaustive information about your vehicle (brand, model, type of cluster, etc.)

Which parameters will show PolarFIS on my vehicle?

The best for this is know your engine ECU and check in our parameters table which of them will be available for your vehicle. You can download on this button :

PolarFIS parameters table

My vehicle not show all available parameters , Why?

Exists 3 main reasons for this :

A) Some parameters are only available for diesel engines and others for gasoline engines. So, have in mind that is possible you not will see all parameters available in your vehicle (all depends on your engine type).

B) Your ECU not support all parameters. Some ECUs not give the values of some parameters and this is the reason why we not show on your cluster (FIS display)

C) For last, another possibility is that you not have some “sensors” and obviously PolarFIS not will read it (for example oil sensor). In this case, the value will be shown at zero (0).

With engine at idle, boost pressure reading must be negative (vacuum), and value is positive, why?

What the Polar FIS does is to read the boost pressure from the engine control unit, and then read the atmospheric pressure also from the engine control unit, then subtract both readings (turbo pressure minus atmospheric pressure), and the value is displayed. If the atmospheric pressure is higher than turbo one, the value will be negative (vacuum while idle as you mentioned yesterday). If reversed, the value is positive.

So you are right and while idling the car should make depression (negative pressure). In other words, we do not design the engine, or your ECU or even the pressure sensor, we just simply read those values that are being updated each moment in the CAN BUS (written by constant telegrams by the engine control unit into the CAN BUS).

What I mean is that these are the values that the engine control unit gives us, we do not interpret at all. In fact, the PF03 hardware has no external sensor or similar, so if the values are “wrong” is why the unit gives them bad.

In fact you can check what I mean because if you use any 3rd party software such as VCDs (or even the original VAG diagnosis stuff) and perform the same operation, with the engine idling, read atmospheric and turbo pressure, and then subtract them, you will see how much gives you… it will be also positive even we all insists whole time on having a negative value that will be more real. This is crazy but is like this.

Honestly, we could invent something and subtract x value to what is measured, so that idling give a negative reading, but who would want an interface to read parameters of the engine if they are distorted or falsed? At least we think from this point.

PolarFIS updater shows me "_FIX", What is this?

For fix this issue, please contact with us at and send us the next information:

  • Serial of your product (8 numeric digits)

HowTo Fix issue (Video)

VAGCOM not works with PolarFIS connected, Why ?

PolarFIS and Vagcom uses diagnosis port for communicate with your vehicle. This means that can appear conflicts in case you try to use both tools at same time.

In the case you desire to use Vagcom, you only need to put in your vehicle any other menu (screen) outside of PolarFIS. Is not necesary to disconnect your unit, simply move to a screen where not appear any of the PolarFIS menus.
