Oh well ..... thought the rattle at bottom of car engine was a problem with the cat converter. KIA dealer today has looked at car and told me it needs new engine !!!!!
Something to do with crankshaft / bearing. Odd as car drives fine but makes this rattling noise low down.
"55" plate car with only 14,000 miles. Warranty ended Nov'10.
KIA dealer going to see if KIA UK will contribute otherwise i will prob scrap car. Said engine would be just undrer £4k and car not worth that!!!!!!
