B4 80, octane plug?
How do?
Coming from an extensive Vauxhall back ground, I am aware that the old mk3 cavs and astras had an octane plug in the engine bay near the bulhead, so that you could easily use different octane fuel by unplugging and turing around the little plug.
I am wondering is there such a thing on the Audi 80 b4 models? if so where?
The reason I ask is that my 1.6i ADA engined 80 runs better on super than on regular, having a little flatspot, if not more like a hesitation at between 2-3000rpm on regular, nothing there on super.
Can anyone help?
