my 2005 rangerover, just had check engine soon light on is that bad? since is the firdt time?
If it still is running fine, then nothing to really worry about, just make an appointment ASAP to take the vehicle in for service. If you have driveablity issue, the sooner the better. A fault code means there is something wrong, you possible can do more damage if you don't do anything, but it would depend on the problem. Just because it's the first time the light came on doesn't mean you can ignore it.
