Hey there guys I'm here because I just ran into an issue with my 2007 bmw 328i e90 2 days ago. First I would like to thank everyone who will be helping me out. I got my car 4 years ago and never gave me any problem just gave her maintenance she took care of me. But 2 days ago I parked my car and when I wanted to go to the store it was dead no interior lights or anything I replace my started and battery about 9 months ago. Took the battery to get checked and its 100% even after 2 days just sitting there. Can someone lead me the right way i don't know what to do to fix it plus its dead and can't run a scanner. Please and thank you

Check for ground cables. These get rusted and can cause weak grounding. Search on this subject...

Thanks Romeo i will check all grounds tomorrow morning make sure everything is intact and not corrosive

could be CAS fried..

Levanime thanks for the info I will look that up also hopefully it's not it. A friend told me to Check the ibs also from the battery i got a donor from another e90 with no starting issue hopefully it works thanks everyone

Hey levanime something weird happened ok so I went to my car about 10 mins ago and guess what it turned on like if nothing had happened all my radio stations saved and audi settings just my time is blank but everything works perfect again I don't know how this happened or what is faulty i haven't even chsnged the ibs terminal but I think i can now take it to a mechanic to scan it. Also the ibs do I have to program it to the car?

So my car doesn't have comfort access i can rule out the (cas) module out right?? I have not taken my car to get checked been really busy what else other than the ibs would be faulty (fmr)??

[M52turbo]

That (cas) module should be located in the trunk right? I'm going to Google it real quick how will I know it's faulty. Will it be by scanning the car the only way if so Ita going to be pending for this Saturday. I skimmed through the forum and read up on a subject just like mine they solved it by changing the fuse box and the b+ cable. I'm also going to check this tonight thanks guys appreciate everything

I had a similar problem with my 335i, with mine what happened was behind the glove box where the fuses are the positive live cable started to break away from the fuse box, when I looked into it people where saying that I would need a new fuse box and positive cable, well I took car to my Indy and he took them out and welded the cable to the fuse box and ever since its been good. So what I done to check if it was that was to get your hand behind the glove box thru the glove box and wiggle the fuse box and at the same time have the key fob and keep pressing button after the wiggle if it is that you will have power u need to somehow get the cable to make contact good luck, this is just a possibility

There was a recall on the Cabin Fuse Box connector .
Was you car subject to and did you have it done.

Pulled the cable and fuse box out. Can't get the cable off of the fuse box. It seems like it's fused on to the prong. Has anyone replaced the cable themselves? If so, did you have trouble getting the plug off of the fuse box?
