MED9.1 Immo off please

[Techaholic]

Good day,

I have read eeprom 95160 and external flash with xprog.

Ecu 8P0 907 115 F
Bosch 0 261 S02 221
MED9.1
Please help me to disable immo on my ecu.
Retrieval of skc if possible as well please.

Thank you

Here EEPROM with Immo off...CS corrected

Just try and give response....also dont forget to press the Thanks & Reputation Button

Hi, thank you Volker. I will try it and revert.

I uploaded the file you provided and safe was displayed on the instrument cluster and didnt start.
I uploaded the original file safe disappeared but still not starting.
I was prompted to immo off my ecu as part of my troubleshooting. Immobilizer advanced
Measuring blocks in vcds stated engine start was not permitted. Immobilizer status 6. Key is
recognised no issues there. Vehicle is a 2006 audi a3 2.0T. The ecu has a different Vin. I require the skc
Of the ecu and instrument cluster to adapt the Vin if immo off isn't possible.
I'm not sure how to retrieve skc

[Volker]

Try this file again...for adaption:

CS: 0C05A19969D320
MAC: 8B59
PIN: 32965

Ok, thank you will try. How do I retrieve the skc from the instrument cluster?
I don't have access to the old ecu and previous owner swapped out ecu to the one I currently
have. I was hoping to extract the instrument cluster pin to use as login to access channel 50.
The guide that I am planning to follow is from the Ross tech website and doesn't need
Cs and mac. Pls provide a guide and or software for this procedure.

I ended up replacing the ecu as it stopped responding. Upon scan with VCDS flash and eeprom checksum errors were present. I needed to immo off the ecu in anycase so I downloaded the external flash with Xprog had to desolder the eeprom(ST95160) and read via TSSOP8 adapter as it could not be read in circuit. Error code was unable to detect SPI EEProm. I then resoldered the eeprom. The ecu was communicating via VCDS then just suddenly lost all communication. It doesnt respond with Xprog either. I noticed that the Power IC heats up as soon as I power up the ecu and this was not previously the case. My question is what would cause an ecu to stop responding? Has anyone experienced this and what was the solution. Could the xprog be causing damage after read or write is executed?

Hi,

My issue hasn't been resolved as yet. Thank you to all who assisted so far.
I purchased another MED 9.1 ecu from a breaker .
I read eeprom and flash via Xprog. I tried immo off using eeprom v2.0 flashed eeprom only to vehicle
dispalys safe as soon as you turn on the ignition and starts but stops running after 2 seconds.
Xprog and eeprom v2.0 does not correct flash checksum only corrects eeprom checksum. Does someone have a tool for med9.1 flash checksum correction?

I have attached the original files as read from the ecu with no vin correction etc.
Please immo off both flash and eeprom including checksum correction I would really appreciate it.

My vehicle is a 2007 audi a3 8P 2.0T DSG
Current ecu
Bosch MED9.1
8P0907115AQ HW: H16
0 261 S02 722

Thank you for the files. I uploaded flash and eeprom immo off. This time however with ignition on safe does not display
as soon as it starts after 2 seconds safe displays and engine stops. The start is then blocked until u cycle negative terminal
to reset system.

I managed to find an original dump online from the same ecu 8P0907115AQ in an attempt to resolve my issue.
Please can someone assist in immo off and cs correction for both flash and eeprom as eeprom only doesn't seem to work. Thank you

P.S.
What would cause the immo off files to fail? Anyone else have this issue?

Thanks again, I flashed both. The original does not start the car just swings and throttle doesn't respond.
With donor files car starts, throttle responds but safe displays and cuts engine after 1 or 2 seconds.

I noticed in advanced measuring blocks on VCDS the lock time for immobilizer is 10.0 after waiting 10 minutes returns to 0 lock time but as
soon as u cycle the ignition it returns to 10.

This happened right after I flashed the initial file u sent. I hope that helps in understanding the issue

Hi Mate!

I need immo off for med9.1 skoda octacia ecu...

Thank you!
