Since I reset my PHEV my phone crashed multiple times and I lost lot of WatchDog data

Anyhow ... my last card from my battery is

171 Days (start from 60 days after reset)

Total charge : 880Ah
Total usage 2104 Ah

Battery SOH 36.5Ah

So ... possibly soon will be time for a new reset

Last 0.1Ah lost happen after 10days from the previous one

So ... 0.3Ah lost a month ... so .. getting ready for a new reset in early 2020

You should test the D-easy method instead, worked for me and my father in law

A couple of points in that video I'd like clarified before I try the D Method:

1) Start Charging - Okay

2) "Turn car on, press the power button twice" - I guess he means turn Accesories on, foot NOT on brake ?

3) As he exits the car the display says OFF

4) He disconnects 12v and then again says the car is ON, although it's OFF ?

5) When he reconnects the 12V the display lights up
The manual says the car will remember which mode it is in when the 12V is disconnected. So has it remembered it was in Accessory ON ?

Could just have faith in the instructions, but like to have some sense of what's going on......

Reply: the car go off when you unplug charger

Tried it a several Times on my 2018 European Type.

with battery-levels (SOC) between 60 and 22%. whatever i try... no chance to get the "Error" message. :cry:

No difference to see on the dog or on the guess-o-meter.

Just applied D method to my one year old 2019 Outlander and got BMU reseted.
According to the watchdog capacity increased from 38.2Ah tp 46.0Ah.

The only difference to the method D I have noticed - once I have disconnected the 12V battery - car have immediately switched off.

HI all,

I just got 1 week ago a 2015 phev with 190k on the clock. After I checked the SOH with the watchdog it was at 68.4%. After several attempts I succeeded to do the BMU reset using the quick method. My EV ranged had increased significantly and using a power meter on the socket I can see the difference on how much charging is accepting.

Before the reset I could maximum charge 7,5 KWH from empty. Last charge was showing 13 KWH. Maybe the chinese power meter ain't the best one but it's clearly accepting more charge and of course I'm getting more range.

When I've done the reset my battery was around 70% SOC. After reset it was still showing 70% SOC but the range increased as 70% from 26AH is different from 70% from 38Ah it's clear that the BMU assumption was wrong. I don't think that we discovered perpetuum mobile :). Drove the car for 10 Km to drop SOC around 50% and then scheduled the charging for the morning.

Yesterday I've depleted the battery within 33.5 Km (12 of them with AC)- I was really happy about it.

After letting the car to rest for 2 hours checked with the dog the SOC - it was only 23.5 %-minimum cell level 3.75V, Max difference 0.012V - somehow looks like I was under 25% - :o :roll: .

I'll keep on monitoring.

From this experience what I can say I think the best moment to do the reset is when you have the battery empty so you would confuse the BMU less than when it's charged.

Have a nice day
