Emissions service warning light.

[Thenewsusieq]

After having my V8 Vantage S 2013 serviced (at AMW) a couple of weeks ago I had the service emissions light come on yesterday morning en route to Brands. Great timing. Not a one off, came on every time I started her yesterday and today. Then this eve I filled up with Posh petrol rather than standard and the light went out......immediately, and hasn’t come back on. Is she just a snooty fox about what she drinks these days or pure coincidence or.......
