My uk99 turbo 2000, had been stood for almost 2 weeks. Started the engine a couple of mornings ago, the engine warning light came straight on. After 5 mins on idle, the light went off.

I did a couple of errands, each time, re-starting the engine and no warning light.

However, started the engine this morning, again the warning light came on and then went off once the engine had warmed up.

Any ideas?

 

you need to check the error code.

My 98 did that after leaving it stood for a while so i did the ecu scan as shown on JGM's website and it though up 22 knock sensor. Still to replace it as the light seems to come on and off as it feels like it with no pattern. Would recommend JGM's site though very easy to follow.
