Misfire at idle

Morning all,

I am in the process of buying a 2006 e85 2.0 with one owner and 70,000 miles.

I have not yet bought it as the dealer has been preparing it, in fact I haven't even seen it! The car is up in Gateshead and I am in Manchester so at the moment I just have a refundable deposit on the car. I had a call yesterday and a video on Whatsapp to say that the car was all ready but that there is a slight misfire when idling which clears when driving. On the video it is impossible to hear anything but I did note that it's idling at around 1200rpm which seems high. Is there a common e85 fault which might cause a misfire at idle only? I don't want to waste time and money driving up to Gateshead to look at a car with a fault unless it's an easy fix, my alternative is to pay for a pre-purchase inspection from a local mechanic.

Any thoughts would be much appreciated!

Thanks, Jonners
 
Idle should be around the 850 after warm up .
From start up it will be higher for a short while.
Was the video.from start up.?
 
Get the garage to run a full scan on the engine with a proper scanner. You may want to read this https://classicsworld.co.uk/guides/bmw-z4-e84-buyers-guide/
