I have just collected my car from a body repair shop after it was slightly rear ended in the snow.

I had no warning lights after the accident and before it had the rear bumper resprayed.

But after collecting it from the body shop every time I switch on the ignition I get the ext light warning, which goes off after a few seconds.

I have checked all the lights and all appear to be working.

Im guessing they had to take off the bumper to do the respray and may have dislodged some cable, but before I ring them is there anything I should press to maybe cancel this warning as Im wondering if it may be indicating there was a problem while they were doing the work but everything has now been reconnected.
