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

 

disconnect the battery for ten mins, i had a similar thing happen on mine. took battery off then the light went out. got a mate to check it on the computer to see if everything were ok after to be safe,

 

needs a code reader, where you based mate?

 

I'm near chester-le-street, about 10 miles from Newcastle.

Will try the battery later, just its pissing down atm lol

Cheers

 

Yeah disconnect the negative lead off the battery for half hour or so, then put it back see if the light re-appears. Chances are you lambda sensor is knackered, very common to go on the st170s, had to replace mine!

 

cheers rich, if it is the lambda sensor, will it need changing asap? or will it be ok for a while? im not doin much driving atm as ive just lost my job, and cant really afford to repair it right now.

cheers

 

Mine was knackered for a while, the light kept coming on and off every now and then. Will affect fuel economy a bit and drove a bit smoother after is was changed!
