lambda regulation is necessary, you can remove lambda for cat status

Car is 2002-2004 Audi A4. You can read it with MPPS, nefmoto, Galletto, or any of 1000000 other K-line tools.

This is not true. On later ST10 ecus, yes. This one is still C167R, MPC is one time write and cannot be corrupted. This ecu also does not suffer from programming errors such as P1681.

There is no danger to read/write this ecu via OBD. An OBD read can be used to recover in bootmode, and the eeprom is generic as well.

this problem has happened to me many years ago, i changed ecu!
i wrote for this reason the safest way for work on this ecu!

[ddillenger84]

There is literally nothing you could do with software to this ecu to make it unrecoverable. It is very safe to work with over OBD. A year or two newer, and your point is valid.

Which eeprom would have to be desoldered?
