You will find that most company do not extend the warranty period on products, your warranty starts the day you purchased the product not when you received the replacement or fixed item.If it was a new car under warranty - and i had used the spare wheel - i would not expect the manufacturer to remove the spare ?
When i have had a new phone under warranty or appliance i have never had the instructions or in the case of a washer the box opened and the pipework removed
Surely if its new the warranty period should start again ?
