Airbag provision Error buffers

Hi, guys!
I am in despair!!!! Although I only delivered 5 cylinders (Type44Q-Avant of 89) with as much firfance as only V8s were delivered. Among other things, an airbag.
Had a familiar problem: dipped light out, contacts v. Steering stick switch burned. Got Ignit. To have switched on to test without having connected airbag, since then the red warning lamp lights. Where is this reset? All VAG people used the diagnostic plugs in the driver's footroom (has the V8 also the diagnostic connectors there?). I've been told in the Audi 100 online forum that there is another plug for airbag diagnostics. It's supposed to be at the 100 in the center console. How does this work with the V8? I am grateful for every tip because even at 3 VAG dealers I could not be helped. This is different with the successor and a 44 with airbag is relatively rare.
Thank you for your answers, czippi
