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.

any serious tuner advise hes client that this model of ecu have protocols instable and bad hardware (wrong quartz and clock gen) and recommend to do R-W only with boot or desolder flash.

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.
