    I suspect you are hearing the high pressure fuel pump, perfectly normal and there are various threads about it on here.

    This could be DMF, subframe brace making contact with the flexi also (mine was fitted upside down)

    I get the same rattle mate, is it like a quick sharp crunch grimding sound on start up then its gone 1 or 2 seconds?
    My car has been back to vaux for a rattling when it is on idle, they replaced the vac pump and not cured it and now they want to fit a new fuel pump. So where we will go from their is anyones guess.

    Is it not just you thinking it’s making a noise on start up for a few seconds sometimes it’s all in the head mate or is it very loud?

    Unless you have had the vehicle serviced recently, and they under brace has been fitted upside down. It's very likely that its a dual mass flywheel noise. If you can post up a video that would help greatly.

    Yes mate agree, my first oil change and the garage had fitted the brace upside down. I believe the round edge should be facing down. Issue only occurred when the vehicle was on a flat level surface. I discussed issue with garage (not blaming them) and they appreciated my stance. But together we worked it out, was really happy to resolve it, I realised anything could go wrong at any time, just wanted it sorted. At least the garage had learnt something for the future eh!
