audi A4 locked bcm2 reading

[davorOS]

hello

Anyone can share information how to read this bcm with VVDI2+VVdiprog?
I have try to read 3 Audi A4 BCM2 all 0711 sw from 2014 2015 cars and can't read any

I try with adapter and with soldering wire but allways VVDIprog say set frequency failed


to me it look like not powering board

and also on adapter I only have PWR light flash
do I need to power BCM from original power connector like AVDI do or I'm doing something wrong?

regards

From 2014 Audi BCM2 have are locked MCU. VVDI prog & VVDI2 can read this module only with Xhorse VVDI BCM2 Adapter.

Audi Q5 2016
0711
8K0907064KP

Was done with VVDI2+VVDIprog+BCM2 adapter

Seem that your orange adapter is broken.

[davorOS]

yes I think it also but I never try it till now and can't return it.

I found few reports with same issue on web so it look like it had to be something wrong

I will have to order update for AVDI and try with that

Seems Abrites have it cracked

not too expensive either

AVDi do not cover all versions, I have friend who got AVDI update and could not read BCM2 form 2015 .
Best tool on market is PolDiag ,very safe and never got any problem with it . VVDI is very danger on Locked BCM2, many people reported damage BCM2 after read or not work at all. Once VVDI brake it , not way to fix it , it needs New BCM2.

try AVDI today and also failed..........
I could read Part number and sw version but I can't unlock MCU,try on two different BCM2 both sw 0711 year 2014

Thanks for link -look like good company

In video it shows 1st eeprom operation - fine by me just as long safe like you say. Also if Abrites is hit n miss then this could be sensible option
