2016 mclaren 650s spider loud on cold start up?

[GRD 8]

Recently purchased a 650s spider from Bristol Mclaren. Not started it for a few days but noticed this morning, on start up from cold on normal settings, that it sounds quite load mechanically for the first few seconds after cold start. Soon quietens down and any subsequent starts are much quieter. Has anyone noticed this with these cars, is it normal? Anyone had any issues with this problem?

Hi, recently purchased this car from Rybrook, started from cold this morning in normal settings and thought it sounded a bit harsh for the first few seconds then quietened down. Subsequent restart quiet. Is this normal? has anyone experienced any problems with these engines?Thanks.
PS New to these forums so hoping i am doing this correctly.

Thanks for the replies, probably nothing to worry about, has got the sport exhaust so that may be a factor, i`ll check it again in a few days when weather cheers up a bit.

Could be the case, just sounds a bit more mechanical than exhaust, came across a noise that was similar years ago when ford released the first Sierra Cosworth. Looked into it at the time and the explanation was the split skirt pistons would rattle a little during warm up and quieten down once warm. In that case no action was necessary. Was just looking to see if anyone had found a similar issue in these engines or if it was something that i need to take a closer look at. Thanks for the replies.

Thanks for the threads couldn`t reply yesturday some problem on PH. Sounds like it could be normal noise judging by your experience of the noise.

Thanks, started it today and for first maybe three seconds it sounded like an engine with hydraulic tappets that have not fully opened then sounded good. Judging by these posts i think its fine but will get it checked out. cheers

Had log book back for 650s spyder but is registered as mp4 12c and in variant its logged as coupe. Spoke to mclaren who have been very helpful and provided me with some documentation to change the variant description at DVLA. Has anyone had similar v5 description probs.
