	immo off M5.9.2 1.8T 8D0907557P 24c02 reading problem « on: November 05, 2015, 09:17:08 PM »

i've been trying to read the 24c02 in an early M5.9.2 1.8T ECU, i attempted to do a readout using an SOIC clip with the chip on the board and my eprom reader would hang when i was trying to read it. i than unsoldered the chip off the board and tried reading it with the clip and i got it to read but the readout just doesnt seem right. all i want to do is shut the immo off on the chip. my eprom programmer is a willem GQ-4X by the way too. the information seems like its doubled over in the readout. i attached the BIN so anyone can have a look and give input. thanks.

after some reading and research the chip did read out fine after unsoldering it from the board. here is my immo off file, i havnt tested it yet but it should be proper.

there was data on that chip that was definitely immo related. the ECU was one that was modifed by total audi performance so who knows what they could have done. the car this belonged to would start for a few seconds and than shut off just like an immo blocking the start up. this car is weird because its a FWD auto A4 1.8T but if you run the VIN through a decoder it comes back as a quattro manual car. its one car that too many people have had their hands in too.

and you determined the start/cut off was immo related how? because there was a fault stored for engine start blocked by immobilizer?

again, 557p does not have immo.
