Hi, can anyone help me with my airbag light. I have an RS5 2010 pre facelift which had wingback seats in. I have changed the front two seats to a mint set of S5 seats as the wingbacks were worn. I didn't realise but I believe these are facelift seats and the airbag connector didn't fit. I have changed the plug from the wingback seats to the S5 seats, the wingbacks had two wires and the S5 facelift has 3. The 3rd being the brown wire. I've scanned the Internet for answers on this and the only answers I can find are to hardwire the connections, adding a resistor 2.2 and 4.4 but none of these options have worked and I still have the airbag light on. It's just this airbag light that's the issue. I've cleared the codes after install but it immediately comes back
