Landrover

Hi I just recently purchased an 05 land rover lr3 it seems to run great and I think I got a good deal on it! But the check engine light is on and the air suspension light that says suspension fault is also on. I have heard good reviews and bad about this vehicle and am now stuck in a hard spot, I have the opportunity to return it and get my trade back and go else where but if I have gotten a good deal and this is a good vehicle and these lights may be something minor I would like to keep the suv. Do you have any advice on what the problems could be and or cost and if this vehicle is a good or bad purchase?
