BMW i4 G26 edrive40 issue with baterry after accident.

Wioletowy · 03-09-2023, 02:43 PM

Hi. i've issue with my bmw.
Ista shows fault code-
1.High-Voltage battery unit; Pyrotechnic safety switch, actuation faulty.
and
2.Impact detection; crash detected due the acsm.
Where can i find pyro fuse ? Its inside a battery pack ? BST was already replaced, Safety switch, who is in the compartment luggage on the right side is enabled.
Best Regards

According to the wiring diagram that I have the pyro safety switch is inside the high voltage battery unit itself.

If you haven't had an accident, then it's a serious fault.

Wioletowy · 03-09-2023, 05:35 PM

Actually, I bought i4 after accident. So what I have to do it’s disconnect battery and go down with it. That fuse will be in rear side of battery module ?

I have the same issue. Did you manage to sort this issue

cruzer666 · 03-25-2023, 03:45 PM

Someone posted this on another forum, I believe the fix was about $20,000. I’ll look for it and paste it back here if I find it. You definitely want to get this taken care of by a dealer though.

Is it possible the insurance totaled the car? Can you give us some more details?

Wioletowy · 05-29-2023, 12:59 PM

everything is possible, after many. researches, I was replace HVS, but actually it isn't DIY, because after replacement we have to code it. Offline coding is not working because this module have coding 2.0 i think. Finally my i4 was woke up by ista online, I've programmed this module to my car and now everything is working.So for anyone who will be follow like me, if you don't have access to ista online you have to go to local dealer to program this module.

cruzer666 · 05-29-2023, 04:33 PM

What was the cost?

Wioletowy · 05-30-2023, 02:22 AM

About 1,8k$ but I have access to AOS online 1 day of session costed about 30-40$. Programming in authorized dealer costed about 300$. Actually i was replaced SME module by myself so we have to add cost of assembly and disassembly battery.
Why I was replace SME? Because inside of them we have 2 pyro fuses pss4 and pss1, actually I think thats regenerationable so if someone will decide to renewal probably will be cheaper.

Dedicated!

cruzer666 · 05-30-2023, 08:12 PM

You did really good! This would’ve easily been $20,000 at the dealer.

Zak7883 · 06-23-2023, 02:21 PM

Hi, I have a Bmw i4 that will not start after a crash, can you help wioletowy. did your car need to go on a eos tester to start it?
Thanks

sunxpert · 07-27-2023, 01:07 PM

Does the car show some error message when the pyrofuse is blown on the dashboard? I have also ordered a damaged i4 from US to Europe, so wondering how can you tell the car actually has this fuse blown..

Krzysiek_KTA · 08-02-2023, 07:14 PM

"Polak potrafi!" Brawo!

Well deserved compliment for the effort.

Yet I have one question:

How access to AOS online can be best utilized for retrofit coding?

My airbag exploded, too
The place where you exchange pyropuses
verify that it is inside the battery

Can't we just exchange pyrofuses?

Do I have to exchange the Sme module together?
be too expensive

MetricMan · 11-04-2023, 06:36 AM

E drive all the way

Wioletowy · 11-14-2023, 03:24 PM

In my case I have to replace sme becouse some of transistors inside module was broke.I want have a calm head, because I don't trust regenerate parts which is responsible for battery. I think that cost of 1.8k$ isn't big investment in 100k$ car.
Actually you have to replace SME, code and programmed it and replace fuse in front of battery. That's enough in case of battery. Every service who make it now hate me

Sorry guys but I love share knowledge with others

PEACE

Your successful i4 repair project is incredibly impressive

Dobrinia · 12-20-2023, 10:37 AM

I have same problems.
After change SME and codding&programming have error LCS.
Car run, contactors closed, but not driving...
Can anybody help?

tytano1 · 02-15-2024, 07:25 AM

So all it took was a new SME and coding,
without EOS tester

ahmedmph · 02-17-2024, 05:59 AM

Dears, I have BMW I4 that had a crash, body work is done, regarding the battery, battery housing was pended, so I purchased new battery housing, SME, CCU and new CELL MONITORING CIRCUIT. all programmed and coded to the car online, then tried to commission the battery via ISTA, got error that EOS test is not performed, tried to perform the EOS test using BMW IMIB HV, received error in step 3 insulation test, can anyone advice what work needs to be done? to fix this and complete the EOS test, BTW I did the EOS test for both EME and it is completed successfully
