Hi all!
Today I tryed to do tune an Audi S3 with the early ME7.5 (512KB) 8L0906018N 0261206796 354092.
Read it without problems, file was 100% original. I moded it and writed it. After that when ignition is on the MIL light is flashing very fast and the throtle body is moving very fast without stop also. Car is not starting and ECU is not responding for another flash attempt.
Made boot recovery. And tryed to fix checksums with tools, winOLS, nefmoto software...all attempts were the same. When moded file is writed it goes the same way every time(no matter OBD or boot writed..also it reads fine in boot mode after mod write). Im attaching original and moded file here. Hope to find a way to fix that problem :/
Thanks in advance!

Does it have a permanent DTC in the ECU?

I think he won´t be able to read a dtc, because Ecu wil start testing routine again and again, during the fact UFM maps are bad touched.

If you touch UFM maps wrong ecu won´t be able to make EGas testing routine sucessfull

But there are more things you´ve changed that you should think about
