Help with a Battery Manager audit? ...
 

Guys; following an ongoing forum discussion with Ross Tech regarding A8 D3 Battery Manager [BEM] ECUs, I wondered if any of you with 'early' A8s [2003 and 2004 cars] could help with survey re. Firmware levels? [Yes, I know there aren't many out there]:)

'Early' A8s had a Version 1 ECU where the battery cable connected underneath the ECU rather than into the middle of it. However, the good thing for these early BEM ECUs is that you can read the label easily [the V2 ECUs, with the cable going to the middle tend to make it difficult to read the ECU label].

I'm trying to correlate actual HW/SW/FW numbers to label numbers, so to assist, you really need a VCDS scan of the ECU as well as to look at the label. All I'd like to know is the first three lines of the VCDS scan of the ECU 61 and the Part number / SW number / version numbers [two numbers to the right of part numbers] off the label.

Note: I'm doing this because some ECUs seem to have a mismatch between the versions on the label and the versions 'found' by a VCDS scan.

Thanks - Julian

Here's mine. I think it's been replaced in the past as it's old software and the WSC is all zeros...

Thanks Matt; but what does the ECU sticker say?

BTW, the original ECUs seem to be 'good'. Yours may have been in the car since new - have a look at the date on the label. Some of the early A8 ECUs tended to have zeros where you don't see them later. My [very early] Telephone ECU has zeros in various places.

Thanks Marcin; but what does the ECU sticker say?

Ah sorry, I'll look later... I'm at work.

And I note that you're following the long running thread at Ross Tech. Looks like your BEM level of 0160 indicates no history logs are stored in it! :(

Julian,
Here is mine, SWMBO is out in the car so I'll try and look at it tomorrow.
