Your Renault scenic 1.4 16v 2004 is juddering when you accelerate?

to me it sounds like an ignition coil problem ive changed mine 3 months ago and now its playing up again try removing coil if you see one with orange powder on the bottom its most likely to be caused by rain water leaking in to that area another common Renault fault, i would replace all 4 coils but don't take it to a garrage as they will charge about £150 buy a set of 4 from eBay for around £40 and change them yourself very easy to do its just 1 bolt per coil hope this helps
