Get any wideband ECU from transverse engine like aum arx awp arx and so on

They costs less than a time you spent on this useless thread

Just Google me7.5 bootmode picture, get a bench harness, short to ground pad on PCB showing on picture, power on and hold for a while

If it's doesn't work, just get another one
changing cpu on a 20 bucks ecu... Is it a joke?

I have this.

Audi (8L) 1,8 BAM 8N0906018BH

Where can I get pin/login code for adaptation?

Thanks.

I have an ecu that has been modified and tuned in the past by an unknown tuning company. They used and soldered some special "flash chip board" in place of the stock flash that contained the tuning maps. This has been removed and only normal flash with stock maps is soldered to its place.

Currently it is unreadable, does not give anything out (normal/boot). Car works though with it.

Plan was to restore this to readable state so that you can read or flash and use diagnostics in car.

Please let me know where can I find replacement ecu for that cheap and what needs to be done to it to make it work if one is found.

Thanks.
