Just fixed a mk1 and a mk2 with air bag lights on.
MK1 2004, was orange connector under the passenger seat. Remade connection, jiggled and fault cleared. In front corners nearest doors on passenger and drivers side. (actually, I did not check drivers side) I think this will get some solder applied in future to prevent it happening again.
Does anybody know if there any issue just taking the connector out ?
MK2.2010 Much better/upgraded connectors in same places. It was not this that was fault.
Issue was the key switch near the fuses in the drivers storage. The cable was disconnected on the back of the key switch! Plugged in and all clear.
I dropped battery negative lead off on this one - after reading more on here.
No software reset was needed on either. Fault just cleared, when ignition put back on.
Wiring is crazy tight and pulled on very short radius, on both models which just feels wrong/odd.
