Wanted - RS4 B5 ECU (swap \ plug and play)

[weta.worker]

I'm after a replacement ECU to swap into my B5 RS4

Stock mapping is fine or options for reliable map with stock gear are good.

Ideally it'll be a plug and play (I have no gear at this end) unless it's simple and cheap for a mechanic to pair \ Audi

Shipping to New Zealand

The back story is , is my mechanic etc has come to a dead end - After a year + of the car being with them for a top end rebuild, turbo rebuilds, gearbox rebuild upon road testing, the EPC light will not go away.

See below...

"Audi RS4, EPC light on. No fault codes.

Secondary air pump not working during actuation test, Check secondary air pump circuit. and found pump has internal damage,
.
Bank 1 VVT solenoid has electrical malfunction when carrying out actuation test, (still works) track fault back to no bias voltage from engine ECU on that circuit.(ECU pins 14 &15) requires engine ECU repair.
VVT solenoids should have a bias voltage of 3.3v when unplugged, this helps the system during normal operation detect whether a electrical circuit is open or not.
Bank 2 has a bias voltage of 3.3v present.

Please not further work may be required after ECU repair. I have not seen a VW/Audi with and EPC light on and no fault codes."

Thanks so much
