Problems with E90 CAS3 - now bricked

**jamesfawcett** · 14th November, 2019, 05:26 PM

I think that VVDI is just giving me the ISN from the CAS, can anyone else confirm? Would that explain why it starts only once?

can you not read the isn from the dme with your tool

I can't unfortunately, it looks like the VVDI2 software is only 1.2.2 with my FVDI

(I hope?)

This comes from VVDI2 using a 2018 FVDI.

I exported the dump, wrote it to the chip and the car started once.

When turned off, it wouldn't start again, is that normal?

ISN is reading as:
4CBEAF4CBEAF4CBEAF4CBEAF4CBEAF4C

That looks like a strange ISN to me though, is it supposed to repeat itself like that?

CAS ISN is FFFFFFFF .......

Thanks - It seems that this version of VVDI is not good enough

I have just ordered a CGDI Prog BMW MSV80 it seems to have good reviews and covers the functions I need too. Plus they seem to be active on these forums too.

Ill update my progress, hopefully it will work this time, I miss my car.

Did you make a copy of the original CAS?
If so, send a file.
Since the ISN would have to be obtained from DME!

I did, but it turns out the original DUMP is also ISTAP too

I think I have been working with the ISN from the CAS, so that is why it would only start once.

As soon as my CGDI arrives I will get the ISN from the DME

Thanks for your help

My CGDI has finally arrived!

It took a while to activate, but I now have all the activations available.

I don't know why everytime I swap CAS and re-write the dump, it will start just once.

**filiprow** · 23rd November, 2019, 08:54 AM

Brother, it seems like you've taken this massive journey to do AKL very far.

You have VVDI2, it's simple. RESTORE original dump to CQS. Choose "file make key" option and tick the box 16 or 64 attempts to start.

Program the key with programmer and try starting. When it doesn't , put key in programmer and click the window where it says "not start". After a few attempts it'll fire up. Done.

If you try doing the same with OBD the tool will mess up your CAS eeprom which happened to me. Car will start once but then you'll have a A0AA code in CAS.
