Any Recommendation for a Car Scanner?
Just read the codes for my Aryia and a vgate car pro 2s. Worked well with the standard obd2 2 profile and gave me the DTCs. Tried the experimental Aryia/Renault profile and it couldnt read the DTCs. However, I can read the ECUs with live data, but not the errors. Tried 2 different devices and the same results. Not sure if anyone has the same problem or I am doing something wrong.

Got it working quite interesting, a few comments…
Turning on the car but no heating on just lights & car background system pulls about 0.5 kW, heating from cold pulls 3 kW at 5C outside initially, but when cabin has warmed up drops to about 1 kW.
Driving on motorway in Eco at 65 mph pulls 10-20 kW and at 85 mph pulls 30-40 kW.
Battery temp is typically 2 C warmer than ambient. I was in a heated garage at 24 C but once driving outside in 5 C it fell to about 10 C in 45 mins. Normal driving and hard driving hardly heat the battery at all, even at 85 mph for 40 mins battery temp was only 9 C when outside it was 5 C.
Battery heater doesn’t do anything at 5 C, no power draw and no temp increase. True at both high state of charge or low. I suspect the temperature has to be low enough for * frost symbol to be on or maybe sub zero before the battery heater activates.
Full battery is 400V, looks like 96 cells each one at 4.16 V, voltage drops as the battery discharges.
Regeneration braking depends massively on state of charge, almost no regen at 100%, maybe 10-20 KW at 85%, 40 kW at 50%, below that 50 kW which is about the max. Regen works every time you touch the brakes, no need to use any special mode like B, but if going down a steady incline that slows you with a lighter brake pedal feel.
Any comments from others using CarScanner?

Just saw your post now, I have my Ariya now on annual maintenance, but I'll tell you some nice to have statistics.Ian Thompson wrote: ↑Mon Feb 03, 2025 9:08 pm Got the hardware Cosmic plugged it all in, selected the profile all working ok. Any recommendation of which sensors to view there are hundreds, found battery coolant temp, traction battery state of charge, which others are useful to display?
About the things you have observed on your latest post, agreed with everything, except with regen, in my Ariya with warm temps at least, I have full regen around 88% SoC.
I can check DTC codes just fine with the experimental Ariya profile with my adapter.karltk1 wrote: ↑Wed Feb 12, 2025 1:11 pm Just read the codes for my Aryia and a vgate car pro 2s.

Regarding your last post about regen braking power my comments were on a cold day it was about 5 C that might limit the regen charge .. it could go higher if it’s warm..
I think in practice youre right though- once you get down to 88% you get ‘plenty’ of regen braking it’s only in the 90% plus range that you really notice more reliance on the friction brakes. Probably somewhat temp dependent because lower the temp lower the max charge rate, makes sense because at lower temps the battery can accept only lower power input.

That's correct, I was talking on behavior on a non cold limited scenario.Ian Thompson wrote: ↑Sat Feb 22, 2025 12:08 am Regarding your last post about regen braking power my comments were on a cold day it was about 5 C that might limit the regen charge .. it could go higher if it’s warm..
