low idle?

[chris2008]

i brought a 2005 megane yesterday and ive noticed sometines when idleing it vibarates really bad (not all of the time) its as iff the revs need to just be a bit more, when i switch air con on its fine and engine increases the revs a touch but when you turn it off its bad vibarting, cars a megane 2005 expression 1.5dci

what indicates the idle-counter on dashbord?
if is normal maybe you need to change the motor stand...

its just below 1rpm it dont do it all the time , wheres the motor stand?

2nd time i have had a diesel, and this diesel dont sound like my last one, but that was a 1996 vectra that never missed a beat tho, can the revs be turned up on these or are they controled by a computer?

I think adrian mgn is probably referring to the "engine mountings". These are a known weak point in the Megane and do cause engine vibrations at idle when they are on their way out.

I have just ordered a new mounting yesterday and will have it installed by the end of next week....so by then I will be able to let you know if it worked. the damage is EUR 111 which should be about 90 pounds...

for the 01/2004 1,9dCi 120 It is part # 6 in this picture:

Is this common on the 1.6 16v also? I think im experiencing the same, also engine nearly stalling when cold doesnt tick over anywher near correct idle revs!

Cheers Ian

i dont get it tho when i put car in reverse it picks the revs back up, do you guys think it could be the choke? cars only done 29k and 3 years old
