All the above pluss fuel and temperature gauge have been sporadically going off whilst driving (the radio too) they will come back on after a second or two but will all come back on immediately l turn the heater fan on! Any ideas or suggestions?

Dodgy ground connection somewhere? Poltergeist? BTW welcome to the forum. Have a search on the forum for faulty grounds. There have been a number of posts with that as a problem. What year and model is the car???

Hi all, I'm getting the same thing happening on my 2005 2.0HDI van once I hit 50mph, abs, battery, airbag, caution warning lights also all come on. I've not tried using the heater to see if that makes a difference. There have also be instances of loss of engine revs and power for no reason. 

Will this need an auto election to fix? I've never been to one before. 

Thanks, 

Lee.
