hi all,

I bought a 52 plate st170 3 weeks ago, it has high miles but very well serviced, last service less than 1000 miles ago.

Took it on its first decent motorway run this weekend, from where I live, near chester-le-street to oakham, about 180miles.

Got there fine, steady 70>85mph, 50mph through the roadworks lol, used half a tank.

Headed back tonight, same speeds about 70>85mph. We stopped at weatherby services for some food and to top the tank up. While we were there a warning light came on, bottom left, orange with a pic of an engine in it.

It stayed on, drove home from there all be it a bit slower, about 80ish miles from home. Everything seems normal tho, all gauges reading within normal limits.

Any ideas?

Cheers Liam
