Cel after BM3 flash

coolguy1o1 · 08-16-2018, 08:41 PM

So after a successful flash of the stage 1 93 octane, I keep getting a cel. I tried online recode and it is still there. I evened flashed back to stock and the cel is still there. Even if I clear the code, it comes back. I attached a screen shot of the code.

This is just a guess but I'm thinking battery. How old is it?

Well this is the hybrid so it has two batteries. The car is a 2013 it probably is the hybrid batteries going out.

Hybrid battery wouldn't be involved in this, it's only powering the e-drive and AC
Perhaps try to flash again and carefully respect the procedure:
cycle 3 times ignition button
flash
ignition off for 30s
then start car

All the while hooked up to battery charger

Completely didn't realize this is a Hybrid vehicle, sorry about that.

Well after talking with ptf and reflashing, I still get the cel with error code p1aa5. I searched it up and a lot of AH3 get them so I'm gonna have to take it to the dealership.

After 5 years, your battery is at the end of its life. Actually well past end of life.

I just got back from the dealership and they said the car isn't showing any codes. They said drive a while and the cel should go away. The only code it showed was "dme temper protection" which happens if you flash bm3 but it isn't causing the cel.

Even that code you got because you didn’t flash back to stock and lock most likely. Your battery is most likely on its last legs or should I say cells
