I am not personally familiar with the TD Sportage since it was not sold in the U.S. However, I can provide a link that might help but there is a problem.

The problem is immediately apparent. These guys are in Thailand and of course their language of choice is Thai. But they do have alot of experience with the turbo-diesel Sportage. You might be able to apply a language translator program. And some of the members do speak english.
There is also an offroad site in Korea but I don't recall their web address. You might want to try some searches. But the site I recall seeing was in Korean.
