Engine Warning Light - New Battery?

[mrjabush]

This morning, I had to have a new battery fitted, as the old one had died. Later today, the solid engine warning light came on and is still there this evening. The card has only recently had a full service. Is this a coincidence? Could the loss of battery power explain the warning? Various other settings were lost, such as radio code, clock date/time, window buttons, etc.

Please may I get your advice?

Thanks, Jonathan

You'll need to have the fault codes checked if you've got a constant engine malfunction light.

usually cheaper to get your own OBD fault code reader than it is to pay someone else to do it.

I have USB one from here  https://tunnelrat-electronics.fwscart.com/

which I use with my laptop, having downloaded free software (Forscan) here:  https://tunnelrat-electronics.fwscart.com/page/help

If you buy one somewhere else be sure to get a 'modified' one which has a switch added so you can access more stuff on a Ford.

This seller has been recomended many times on the Ford owners club forums and is where I got mine from
