ECU flash with no power supply

Hi.
I'm intented to flash my EGS in my F48 .
Could I execute the flash procedure (using ESYS) if I don't have an external power supply , assuming that the whole process doesn't need so much time ?
If not , then could I use another running car with his battery connected to mine's ?

Thanks in advance.

EGS is quick (~ 5 minutes) and can be done without external PSU.

You would need a charger if doing module like HU.

Thank you very much Almaretto !
A final question :
My current I-Step is 19-03-530.
The Psdzdata full I will flash EGS with , has the version 19-03-550 .
Will there be a problem since the rest of the ECU's have the 19-03-530 version ?

Impossible to predict, but likely not.

The versions are very close. It is possible EGS does not even have an update though.

Thanks Shawn.
I want to flash EGS because I need to resolve the "transmission problem" on the IDrive.

It is a known problem for F48 and F39 that many people reported that dissappears after updating EGS.

Ok, good luck with it.

As Shawn stated, impossible to predict. But, checking dependencies will help guide.

What would you think about flashing a TV Module without power supply ?

I flashed my PMA2 in 1min:18sec without power supply, and that is connected via CAN bus only. The SW for PMA2 is 358kb, the SW for TVM2 is 14.2MB, but connected on the MOST bus to headunit, so I would assume that 14.2MB could be send rather quick via E-Net to HU, and via MOST til TVM2 ?

Anyone know the time for flashing TVM2 with E-sys and E-Net cable ?

Off course, this is assuming that MOST devices can be flashed with E-sys and E-Net cable, but this should be possible.

All Modules can be flashed with ENET. It is only E-series that require ICOM B for MOST.

As far as time, I know not; hopefully someone else can answer.

Great

I might just give it a go then, 14.2mb is not long over E-Net/MOST speeds

By your logic above, it will take 52 minutes.

Yes, I have also calculated that, but wouldn't MOST be much faster than CAN2 bus ?

I would not do it if 52 minutes is expected.

I read that headunit is about an hour, but that is multiple gigs of data for all SW modules combined ?

Off course, that is E-Net only, not routing through MOST.

Just tried to start the TAL processing offline(off course it fails), and it shows estimated time of "14 minutes" of the video module 14mb file.

The PMA2 showed 3 minutes estmated and took 1:18 for 348kb file.

So, I think it should be safe to try and flash the TV module without a powersupply. My guess is that it will be less than 14 minutes, and the battery should be able to hold that

This is my guessing, is that completely insane to try ?

Why not jump to another car and not worry about cutting it close?

Used my girlfriends car, worked like a charm, video module flash took 10 minutes and 18 seconds via E-net/MOST, so I guess it would have been no problem on fully charged battery But better safe that sorry

I finally flashed my EGS today , without a power supply !

All OK , since it only lasted 3 minutes.

The only dissappointing was that I did it trying to eliminate the "transmission problem" on the IDrive , but the errror still remains.

What is the exact error message? Did you also check ISTA+?
