There were quite a few versions of the Astra in 95: which one is yours? Engine size/code would help. Has it actually got an octane plug? Are you in the UK?

I removed the "conversation" you were having with tommyboy as it wasn't relevant to your question.

Ah; so this isn't a UK-spec car? All UK C14NZ cars built after 01/01/93 had cats and thus could only use 95RON unleaded [that's all there was at the time.] Only the leaded/unleaded non-cat ones really needed octane changing plugs. Yours should be a reversible 220 ohm one for standard unleaded if it's UK spec, or a zero ohms one for export markets using 91RON fuel. What's the problem you're having?

Yes; 95 was standard for the UK; turn it round for 91, but neither will cause pinking. Have you checked the timing. These are set mark to mark; that pointer's 5 degrees, not a TDC mark. Or is there some diesel in the fuel. When/why did it start doing it?
