    So youíre trying to retrofit the SQ5 exhaust sound booster to a 190hp 4 cylinder TDI? Iím pretty sure it has the same vehicle and engine type protection as the inside borne sound actuator.

    Easier would be to get the sound booster from Kufatec.
    I get harness from k-electronic so they give me pdf installation guide also using elsa and SQ5 exhaust from ebay but nothing works maybe problem with C0 module 4G0 could be 8R0 works

    I don't really understand why someone would fit an actuator for exterior noise. Those are used on PHEVs and BEVs to warn pedestrians that a vehicle is approaching because those vehicles are "too quiet" without them. But this does not appear to a vehicle capable of "silent running".

    Uwe: clearly you are correct. I was responding to the title heading on the thread - but there's a problem with the definition of terms: "Soundakator" versus "Sound Booster"

    Your problem is the engine type. These modules are married to a certain engine type and if it does not match, it results in the error you're having at the moment. There is no way you can change it unless you can fool the sound booster module to think you have SQ5 engine.

    Many have tried to retrofit the internal sound aktuator and those fail in the same way if the engine type does not match.

    Edit :

    I would guess this kit is what would work for your car : https://www.kufatec.com/en/audi/q5/q...di-q5-8r-41380

    Not original VAG product.
