Firstly hello to everyone, I'm new here :-)

I have 2002 (52 reg) Stilo JTD, 5 door active.

I've got a yellow triangle with an ! mark flickering and dimming, I had it before but after having a new wiring harness fitted for a preheat fault it went. Then a week later it came back but this time it was a blown bulb, after a new bulb, it went again. However its come back and all the lights are working. There are no fault messages with the warning light. When it came back on it was solidly lit for a few seconds then just flickers and dims. I've no idea what this could be.

Could there be an electrical problem somewere?

Any advice or suggestions would be appreciated.

Thanks

Phil
