E93 ISTA TREE ERROR
Hi

Hoping anybody can help me out with this one please, I have a 2010 E93 330D factory fitted with CIC+Combox but I have this error on my ISTA (CCC_0xA0) when I tried to "Call up ECU Functions" it goes red and says can't communicate with ECU.

I've posted a screenshot hoping anybody knows how to correct this as my car has never had CCC fitted and no idea how to remove it

Many thanks to anybody who can help

RE: E93 ISTA TREE ERROR
Is there constant communication with A0 in Tool32? Is I-step factory saved in CAS and FRM match the real factory I-step?

Thanks for the reply, I have very little to none experience with Tool32 
also do you have a step by step how I can check the I-step please, I did a full update with ISTA-P a few days ago and everything updated fine but the MOST configuring wasn't backing up and restoring.

RE: E93 ISTA TREE ERROR
Check your car's options list (you will need NcsExpert or Tool32 for that). ETK indicates there are retrofitted codes registered at BMW. OKOS in particular. Never seen such code before (or forgot I've seen it), but maybe it does something.

Thanks for the reply, I've just removed OKOS from CAS/NFRM and recoded the whole car. CCC is still showing in ISTA

RE: E93 ISTA TREE ERROR
I see this quite often and just ignore it now due to the amount of cars I've seen with it, I just put it down to an ISTA bug
