I pulled my tune a month or so ago trying to sort out a fuel economy issue, put it back yesterday. Think I got the FE issue solved - dragging brake, but had a bit of trouble getting the Polar restarted after re-installing the tune. After some digging I found a suggestion to pull fuse F24 under the hood to take the power off and force a hard reboot of the Polar. Something worked because after holding the OK button for 30 seconds I was able to get back to the Polar screen.

I miss my PolarFIS but then again I don't. I never knew any of those parameters before and really wasn't any better off once I did. More like I became a slave to the numbers, not that I really had any control over them.

Fingers crossed that the Bosch cheque shows up... Hello Malone 1.5!

Mine works sometimes correctly. Must of the times not. I have several tickets with auto polar . It will work for a day then quits right now my radio turns on and off frequently. I will remove it when I have time. What a wast of money

Mine did that. Turns out they sent me one someone sent back to them. When they replaced it with a new one, I installed it and haven’t had a single issue since.

When they work. (y)(y) They are temperamental tho

Would really be in the dark to how much soot reduction a tune does without the input. Worth it for just that alone IMO. Some owners dont want input, generally those who's cars run a troubled life.

I have a Polar FIS pf04 and not a single problem, it works great. The only thing was that my MK5 TDI 2010 had an Android Radio and it won´t turn on with the Polar FIS so i installed a OEM radio and everything is fine.
