Picked up 1992 volvo 940se Turbo Yesterday

Hi Folks, Drove from Glasgow to bolton to pick up a 940 se turbo with full service history 125.000 on the clock. Drives no problems, very resposinsive. Very pleased, has passed its M.O.T. no problem, and I am quite Delighted. There is only one thing that is niggling me, quess what warning light is on, yes youve guessed the Lamba light. She driving fine, I notice in the service history that a new exhaust was fitted at 50,000 miles. Don't know if it's been on since then. What would be my first port of call in troubleshooting. Thanks Seye

Try disconnecting the battery for 15 minutes. the light cansome times come on if it has been stalled. This should clear the light. If there is still a problem check the air breather hoses to the turbo. Failing this you can get a readout from the led in the engine compartment. It gives a good description in the Haynes manual.

Don't forget if you disconnect the battery you may loose the radio!! make sure you have the code first?:Banane32:

u dont need to to pull the batirey just fuse no 1 and fuse no 2 or top row last 2 on the left hand side as u look at it

Hi Folks, Disconecting the battery worked thanks. Had already done the job before pulling a fuse was suggested, try that if it comes on again, Cheers Seye
