Hi community,

I have an AUM ecu that has already been optimized (not in my possession). This one is not good and I need to reset this to original. Unfortunately I don't have the original file. So I thought to myself if I could play the APY file on it? As with the newer models, are there also BDM files for the ME7.5 that I can simply play on it and it works or do I have to play the APY file with the appropriate EEPROM on it?

I would be grateful for any help

I don't have a camshaft adjuster. A 1.8t ARZ was installed in my Golf 3. With a k04 upgrade charger. The AUM has a camshaft adjuster which I don't have. I'm also not so good at programming it from the ecu. I'll test the k04 upgrade loader anyway and try to optimize it myself.

An ARZ ECU would also be enough for me, where I don't have a camshaft adjuster.

İ just have apy ecu. My arz ecu got robbed. Can i play the file from the arz ecue to the apy ecu?

Should be crossflashable but im not sure

Dhare a story of ecu robbers 

i have a aum ecu. my question is: can i change the aum file with my original arz file?  can i change that or do i have to change the eeprom to make it work or is there a bdm for the me7.5 control units?
