When you say it's rough in the morning, what do you mean by rough exactly?
Mine when first started in the morning, sort of judders in bursts of about 5-8 seconds when cold, and I can hear a very feint knocking noise when it's juddering.
Is it something like this? If so then I gots meself a problem aswell
