Hi, I work on a swap project (polo gti 9N3 motor install in golf1 GTI).

I would only use the minimal wiring. I've make an immo (standard two bytes in 95040).

I've delete all electronic units from the donor (ABS, GATEWAY, CLUSTER ...).

Today, i've test to scan the ECU with VCDS just plug to the light harness (without any sensor).

First test on the first ignition on:

                Address 01: Engine       Labels: None
Control Module Part Number: 06A 906 032 TL
  Component and/or Version: 1.8l R4/5VT     G01 0040
           Software Coding: 11510
            Work Shop Code: WSC 00210 
           Additional Info: XXXXXXXXXXXXXXXXX     XXXXXXXXXXXXXX
                     
11 Faults Found:

16622 - Manifold Pressure / Boost Sensor (G31)
            P0238 - 35-00 - Signal too High
17069 - ECM Power Relay Control Circuit (J271)
            P0685 - 35-00 - Open Circuit
18057 - Powertrain Data Bus
            P1649 - 35-00 - Missing Message from ABS Controller

18017 - Crash Shut-Down Activated
            P1609 - 35-00 -
18048 - Internal Control Module
            P1640 - 35-10 - EEPROM Error - Intermittent

After cleaning faults, only EEprom error disappear.

I've few question, this ecu can run fine in the swap car without limp?

If I code out all DTC (conventional method), it's enough? Or need another trick?

I think delete air pump, evap, vehicule speedsensor (no speed sensor because info from canbus), N249.

Why is stored "Crash Shut-Down Activated" ? Maybe because donor car has crash his airbag? who send this dtc? this dtc is stored because message send by airbag module and only airbag module ok can clear this dtc?

Thanks for your help in this project.
