#1: Loud engine knocking/rattle Author: Dan206, Location: SwindonPosted: Fri Dec 17, 2010 6:40 pm ---- Can anybody help? I have quite a loud rattley knocking noise coming from the engine of my 1.4 hdi, its mainly when its idleing it sounds like something is knocking together. Gets really annoying and is quite embarrasing. Its ok pulling away and when driving however you can hear it again when slowing down. Does anybody have any ideas? Thanks

Also is it safe to drive or am I going to ruin the engine?
#7: Re: Loud engine knocking/rattle Author: mjsroofing, Location: south walesPosted: Tue Dec 21, 2010 4:00 pm ---- would this also cause the engine to shudder when pulling off in first.
#8: Re: Loud engine knocking/rattle Author: panason1c, Location: SomersetPosted: Tue Dec 21, 2010 4:02 pm ---- Defo the crank pulley, had to renew mine recently, £55 off ebay, fitting is a very easy diy.
would this also cause the engine to shudder when pulling off in first.
No, the pulley rattles when its u/s but it doesnt affect engine performance in any way.

ok thanks mate, i dont know why it does it, it only shudders as you pull of as though you havnt got enough revs but it dont matter how much revs you give it, never mind i'll sort it after xmas now.

No, as on HDI's the bottom pulley can debond and rattle
Compared to TU engines which have a static pulley, yours has another problem unfortuantly

It's a fairly common occurance for the cat to break up and cause a rattle as it is quite a fragile/brittle construction and easily damage if the exhaust receives a sharp knock.............could well be the problem in your case.
#14: Re: Loud engine knocking/rattle Author: robertmarcs, Location: carmarthenPosted: Wed Dec 22, 2010 3:13 am ---- u checked the engine mountings?
#15: Re: Loud engine knocking/rattle Author: Antknee, Location: ManchesterPosted: Wed Dec 22, 2010 4:52 am ---- check the air intake at the back of the engine, mine came out and was rattling away
#16: Re: Loud engine knocking/rattle Author: chris001, Location: BournemouthPosted: Wed Dec 22, 2010 7:43 am ---- Its only makes a noise when idling, when I accellerate its ok. The sould is coming from under the car in the middle between the front seats and engine - so that sounds to me like it would be the cat, however only got the car the other day so have not had a change to look at how it goes together under there. I'm going to put it on ramps tonight and check it out. Has anyone changed the Cat before and is it straight forward
#17: Re: Loud engine knocking/rattle Author: Antknee, Location: ManchesterPosted: Wed Dec 22, 2010 9:19 am ---- mine sounded the same, and took me ages to find it, just look under the bonnet first and see if anuthing is loose, might save you time and effort
#18: Re: Loud engine knocking/rattle Author: CRWCars, Location: PenzancePosted: Wed Dec 22, 2010 6:41 pm ---- Not possibly the heat shield at the front of the engine.? Have known those to rattle against the exhaust, think they slip or get loose and vibrate, can sound quite noisy!
#19: Re: Loud engine knocking/rattle Author: chris001, Location: BournemouthPosted: Thu Dec 23, 2010 2:26 am ---- Jacked up the car last night, its that cat thats shot, i drove it for a bit and the cat stopped rattling so now it looks like its totally gone and the exhaust is blowing a bit from the same area. I must have knocked it somehow.
It also looks like the hearer matrix is gone, i'm seeing puddles in the footwells and the fluid smells the same as that in the water bottle.
Looks like a bought a total pile of s**t
