Depends where you drive
If you drive in a hot desert - then it'll be round quick.
(Just because there is a hosepipe ban in summer in Essex it doesn't count)
Check yours through your stalk or idrive (delete as applicable).
Mine is going to be due at 43k - but as i've seen it may not really of relevance to any non si cars. As the sparks were changed at 25k ish.
