Just wanna say Hi to everyone in this forum. I got my '02 Disco II the other weekend so I'm new here. I would also like to take this opportunity to bounce off a few questions while I'm at it. The same day I got my Disco, the "Service Engine Soon" light came on. I attributed this to the gas cap which I thought felt kinda funny when I gassed up. Anyway, I retightened it but the light stayed on for a week before it went away. Any thoughts about this? Another problem that came out after a few days is that the driver's door lock started sticking. I said sticking because I can see that it tries to pop out or in but is sometimes successful and sometimes not that I have to use my key to open and lock my door. Does anybody know if there is a simple fix to this without me having to take the truck to the dealership? One last thing, when the vehicle is in motion, there is some kind of a low pitch whining sound much like the sound of those old army jeeps with cross-wise threads. Is this normal? I have been monitoring this forum for a week now and I must say this is great and I am glad to be part of it. Thank you very much!
