Video covering EWS: • Early BMW Anti-Theft (...
In this video, I go over the basic functionality of BMW's CAS antitheft system that was implemented in virtually every BMW beginning in 2005 up through their current lineup. The CAS design has seen a few changes since then, however, with the most prominent being the change from the rolling table of codes to a singular, static 128-bit code. This helps to prevent issues where the codes stored in the CAS module and the DME would fall out of sync with each other and not allow the car to start, despite neither of the modules having failed.
only 70 views, but so much information in 5 minutes. best vod i've seen.
Thank you so much!!!
CAS has Starter relay within it the same as EWS system, do not require a DME installed to crank it is independent once you have a matched key.
You 've explain something new I never seen any one identify the system as you did... Good job from Morocco
That was very helpful and informative. I have this exact situation going on with my BM W. Thank you so much.
Excellent video. Definitely a lot faster than reading TIS. Good stuff!
Great video, now I got a better understanding. I change the transmission solenoid on my 530i after that car not starting now I guess it went into antitheft mode
You ever get the anti theft mode fixed?
Priceless information in 5 min only. You should concentrate on the BMW stuff as you are very good at it. By the way where did you learn all this information? Thank you
Thank you for the explanation although it did make my head swim. Good luck with you channel.
really informative thanks for this..
quick question,
would a CAS module from a 3series e92 work on a 3series e90?
if theyre in the same class would the CAS module be the same so to speak?
thanks again
Theoretically that should be okay, although I think that you would have to swap over the other partnering equipment too (ring antenna and DME) since they all communicate with each other.
I have a a0b3 error on my 335d e90 2011 but the car starts fine, unlocks fine ( I do need to be like 5 meters away from it, it won't unlock from a big distance) what could it be ?
real informative video thank you.
Great video. Thanks

i have a 2013 bmw x5, i needed to copy a blank key. based on your video, it is using cas. what do you recommend what to use (tool) to program a blank key

But says INVALID when last start attempted
Regarding code from key

How about EWS - what car models and years on EWS?
Long story short I lost my key to my bmw e90 and I called a locksmith guy to program a new key to my car , he couldn’t do it for some reason , so I just decided to buy a new one from the dealer , when my new key from the dealer arrived it wasn’t working at all , called the locksmith guy back told him what’s going on , so he came back and tried to fix it but couldn’t do it again , but somehow he was able make a different key work but The car only unlocks , locks, opens trunk , cranks but engine doesn’t turn on , please any help would be appreciate ,
Dude thanks.
You are wrong about starter.
This was extremely helpful. Thanks!
Good stuff
Interesting, this mechanic put in a N51 cas and dme in my N52 while he works on my cas to add a keyfob. Car starts and drive but I have codes so I don’t bother on driving it. Why are the electronics so damn complicated lol

The information could have been great but you were so incredibly boring I couldn't get past 45 seconds. Not trying to hate, just offering my thoughts. Maybe try being a little more excited to share the info...
