Immo OFF Sharan 1.9 TDI 0 281 001 251/252

[uferi]

Dear forum members,

I fight with a Sharan (1.9 TDI, 1Z, 0 281 001 251/252, 028 906 021 P), I tried to resolve from immo box (5WK4 776), doesn't work with the trick with 00 AA AA, I tried to modify the eeprom contents from the ECU (two 93C46), the car started twice and at the third probe fall.
Now I want to change the software from the two 27C512 eprom, somebody help me with a working eprom dump? I found on the dk forum some 1Z 27C512 off dumps, but they are very different (shorter than the original)...

Thanks is advance, best regards
Feri

The picture No. 3 there is eeprom chip, sitting left/ middle.
What number that chip is?
It should be 24C02, if is 24C02 post file here and I will do immo off.

Hi,
this type of ECU doesn't have I2C eeprom (24xx), this type of ECU have 2 x 93C46 memory (Bosch code B58323). Please see to the attached picture (I put red circle around the eeprom chips). I tried solution with eeprom, but doesn't work reliable, the car can starts 2 or 3 time, after that stops. So I want the reliable solution with software modification on eproms (27C512).

Best regards,
Feri

I think you are confusing Immo box and Engine ECU.
To me it looks like pic # 1 is Immo box.
And Pic # 2,3 and 4 ECU.
Correct?

Hi,
all the images are ECU images!
I put the image of the immo box, but I repeat: I tried a week ago the solution with the byte string 00 AA AA, does not work on this item!!! Because this I want the solution with software modification from ECU.

Hi mecano_diag,
I know this type of solution (I made over 10 cars with immo box Siemens 5WK4 678), BUT this type of immo (Siemens 5WK4 776) has a little bit different dump comparativelly by 5WK4 678. So I tried a week ago this solution, but does not work!

OK, this is MSA 11 EDC ECU.
You need to do Immo off only on right 93C46.
Did you do just one of both of them?

Hi,
forum members, finally the car was solved by the classic way: a transponder chip, login and key learning procedure.
Thank you for the help and support!
The login code of the original D33J mask processor is 00137.
I can't made more and more tests because the vehicle was at huge distance from me...

Best regards,
Feri
