W210, 210 545 02 08, with two 1D69J, not turning.

[Eskerra]

Hi, good evening.
We have in garage a W210.
Initially car had problems to recognize its keys, car had two keys.
Sometimes was working fine at first try, and car started, sometimes had to try several times to make it work, and other times it simply didnt want to work.
As said this very random, one day fine, then two days faulty, OK.
We took an used unit with exactly same reference, swapped its processors over, the two 1D69J.
Installed all back in car, and....doesnt work.439532439533

Could it be that maybe its a software matter, instead of EZS hardware??

I attach both dumps, inner and outer processors.
Would appreciate if anyone, please help me to see if they are fine, or its info its corrupted.

Thanks so much in advance.
Regards

Thanks for reply Juxa.
But we have even changed those processors, and the problem is still there !!.

Thats why, we maybe think its more a problem of software (dumps maybe corrupted).

Thanks again.
