Ews-dme sync code

[kabstyle]

I had disabled all the keys with pa soft.. now i have connected the pin 4 to pin 8 and erased the ews3.
I have backed it up and All that Stuff but the backup didnt saved the ews-dme resync code
So now after i have coded New keys with ak90 i cannot resync ews to dme Because of the isn number in ews is FFFF and in dme its Another..
So all i have is inpa, inpa cable ista, ak90 and bmw scanner 1.4.0
So the question is how do i read the isn number from dme to resync ews with dme. Car dosent start or crank

What car, what dme/dde? That's the most important part. There are so many ecu types and each requires a specific method, if there even is one.

You have to rebuild the ISN in the EWS. Original ISN is probably lost. Send me a PM with your email, and I can try to help with some, when I have time. But you may also need to do a BDM read of your dme now.

Do you have all your current key data saved? Actually it should not be a problem if you have ak90.

Did you figure it out? I'm getting a cas code because I got a used DME. Wording if you can align the ews to the used DME.

His DME, EWS, and car is completely different than your car (135i). He solved it by reading the ISN from the ME9.2 dme with a bdm read. Completely different than your situation.


Why are you changing your DME? Your particular DME (MSD80 or MSD81) and CAS requires some expensive aftermarket tools to link up. It has very difficult security built in.
Do you still have the old DME?

[Fallen Leaf]

Yes I have my original DME msd80

Unless someone on here has Autohex II, you'll want to contact G coding BMW. His number is (985) 492-0666.
He has the tools to sync a used MSD80/MSD81 with your CAS module.
