well when i start car in works car park its almost always tappety. i dont thrash it to and from work (i drive equally both ways)
but when i start car in open car park at work where its been sat in heat for 9 hours its almost always tappety for a few mins
but when i start it at home from "cold" its fine
any ideas why it only does it in my works car park??
