    Hello
    I transfer the AUQ 1.8 20VT engine from Octavia VRS from 2004 to golf 2 from 1986.
    I am looking for a wiring diagram for the engine, or a pinout of driver No. 06A906032HN.
    None of the schemas up to 1.8T for ME 7.5 m available on the Internet or in the "Autodata" type programs did not fit - the following also does not quite coincide , the bundle lacks installation from the flowmeter, I have unused pins normally responsible for the flow in AUQ, i.e. pins 27, 29 and 53 and the installation was not cut. Factory without a flow? The controller has 2 cubes (wider and narrower) according to available power and ground diagrams to the controller agree with me "reality" while some sensors are also connected to other pins than it is described in the diagram below or Autodaty.

    Did you dismantle the beam yourself? Do you have any harness connector matching the grommet?

    I have already got the harness disassembled together with the engine, ECU and all accessories. The seller denies that everything comes from the broken English Octavia RS from 2004. The beam was unfastened at the pit and next to the battery - nothing was cut. Only the MAP plugin was torn out but I already managed it. I don't have a flowmeter cube anywhere. Anyway, I have a slightly different driver pinout than the one in the diagram.
    I thought I had a bundle not from 1.8T but ECU cubes are visually the same as other ME 7.5. There is MAP, there is a phaser, wideband, narrowband probe, EVAP, SAI, solenoid valves from ecology, N75, the beam fits on the engine - it is arranged as if it were from this engine, no 1.8T like nothing. But the ECU pinout is a little different.
    I still have an installation from an Englishman with audi a3 from 2001 AUQ 1.8T with a different driver number and there everything agrees with this diagram. This is not all and I do not know how to bite it, because I have nowhere loose wires to which I could connect the plug from the flow meter.

    If you have such a possibility, enter the chassis number from this donor.

    The seller does not have a VIN - I have already asked him about it. I can still connect the controller "on the table" and if someone did not cut the VIN from the software, I will give it to him.

    Unfortunately VIN is cut.
    It's difficult, gentlemen, I'm looking for a different bundle, it's a waste of time to play with it because the client is waiting.
    Thank you for your interest. Subject to delete. best regards
