Recently when starting my octavia from cold ie first thing in the morning, it sounds like a bag of spanners is being shaken around under the bonnet.

The noise seems to stop within seconds once i drive off in a morning and when i return to my car after 9 hours at work the noise is not present :confused:

This has only started in the last couple of weeks. I have booked the car into a local dealer but it is still going to be 2 weeks til it goes because i need a courtesy car.

any advice on what this could be???

Is this an Octy RS? Always happens on first starting in the morning?

Generally this is normal...revs a quite high and then settle to 1k or just below....VVT sorting out the emission.

You are not he only one to be experiencing this little quirk.

There have been a few threads on this subject in recent weeks.

Dont know if anyone has got to the bottom of exactly what the problem is though but mine does it too! Its not a pretty noise :thumbdwn:

If its the same noise as mine then that isnt it Adrian. This is a new and very unpleasant sounding grating/grinding/rattling noise. Havent been able to pin down where the hell its comming from but its deffinately under the bonnet!

10 seconds after you drive off its gone and doesnt come back till the next cold/damp start :confused:

it is a 1.8 Turbo Elegance. And i am not sure it is normal. It nevr used to do it :confused:

I is a metallic rattling sort of noise and can be heard from inside the car too.

I thought maybe a heatshield or something could be loose but surely the noise would be there all the time? not just on a cold start up

Si,

never sure what people are describing hence why I used "generally".

It may be the secondary pump " for something"...can't remember what the "something" is...in another thread.

Thats what I've got.

Hope its not an expendive job as I've invalidated my warrantee

hmmmm there was a thread on here yesterday about a similar rattle. I took mine to the dealer who could hear it but not find it - they spend half a day looking for it and charged me nothing - unknown to them its not done it since!

I suspect they tightened something up.

The engineer in me thinks its going to be a loose guard/sheild over the exhaust or something. It probably expands when hot and buckles to hold itself tight.

At last, I didn't realise this was a common problem.

My 4x4 has been doing this for a year now, took it to the dealers 6 months ago and it didn't perform for them (as usual) and they couldn't find anything lose etc.

It's exactly as described, only ever does it in the morning, never going home from work. It has been getting worse in the last week, is it the weather?

It can sound really serious, but it can't be that bad 'cos I've had the problem so long now.

I'd love to know what it is

My vRS was doing this for the last year. When the engine was warm I could re-produce it at low revs trying to set off in second gear, which would suggest a shield was loose or the clutch was at fault. I never got to the bottom of it and have now traded the car in so cannot offer a diagnosis. It may be a good idea to leave your car with the dealer and explain how to re-create the problem in order for them to re-produce the noise when the car has been standing over night.

There was a suggestion a while ago that it was the turbo rattling, but I doubt this very much as power loss was never an issue, and nothing went band on full song.

Some bright spark in a previous thread on this subject suggested it could be "the secondary pump or the cam chain damper"

Dont know what either of things are (although I could hazard a guess) and I dont know if anyone has been able to prove this theory.

I bloody hate intermittent faults!

I could sometimes get mine to do it on cue by trying to move off with the hand brake on. It'd do it that way even at the end of the day with a cold engine.

Right i had the bonnet up yesterday morning, got the wife to start the car and i had a listen in the engine bay area.

When the car is ticking over it sounds ok, however when some load is put on the engine, that is when it starts making the noise. I dont think there is anything loose under the bonnet.

One thing i did notice is that when the car is fired up first thing in a morning, the engine is generally louder as if some sort of "choke" is in operation. However this is only for maybe 30 seconds at the most and when this stops there is none of the rattling sound, even when under load.

The car drives absoloutley fine.

Any more ideas?

Does it sound like any of the noises described in the FAQ below?

http://www.briskoda.net/cms/Frequently_Asked_Technical_Questions/General_Skoda_Questions/Should_I_be_worried_about_unusual_noises_from_my_1.8T%27s_engine?/

No i don't think it is any of those.

It lasts longer than just a few seconds. Maybe 30 seconds.

But like i said it is only when the engine is under load.

Grab hold of this pipe when you're getting the noise (bottom right of picture), if its vibrating like mad in your hand then the secondary air pump is running. When the pump stops, this pipe will stop vibrating.

At least you will then know if the SAP is possibly making the noise.

thanks for the suggestion, will try what you have said and get back to you.

thanks again

Just been deleting old pm's and I recalled a user called 'kostas' who asked me about this last summer. After I told him I had no joy with my dealer, he took his 4x4 in and had it checked out. The dealer found that the rattle when cold was due to a faulty water pump which was due to be replaced under warranty.

I never got any more correspondence from him over this, so can only assume this information to be correct and his fault was cured. I would suggest that those folk who are concerned should contact this member and ask weather his rattle from cold was cured by having the water pump replaced under warranty.

Hey I had something like this with my old Laguna (yes, before I'd seen the light, but it was a hand-me-down company car which I bought when the lease was up), and it turned out to be the cat rattling against the heat shield above it. It only started after I had a new back box put on the exhaust, which wasn't quite long enough so the lads had to move things around.....

Have you had any work done to the exhaust recently?

SR

i have had a look to see if it is anything to do with the secondary air pump.

Started the car yesterday pm, got hold of the pipe, it was vibrating but the noise was not to be heard anyway so i guess it is not anything to do with that.

Also i have had no work done at all to the car since i got it so that rules out the cat thing.

After the car had been stood all night since about lunch time yesterday. I started her up this morning at 6am and the noise was there again. I am begining to think it may be coming from the end of the engine where all the pulley wheels are, but i will need to investigate this further.

It is going in to the dealers a week on thursday but am just a little worried that something may just suddenly "go" on me.

The dealer it is going to is F. R. Pulleyn in York. has nayone had any experience with them?? I have been to Barkers in Hull a coupleo f times for minor things and have not been impressed.

I would guess the CAT element may have come loose, and a new CAT converter may be needed.

Hope your car is under warranty as it cost

It's circa

it is still under warranty.....thank god.

I dont see how it could be the cat. surely if it was then the noise would be there all the time. not just for 20-30 seconds on a cold start up????

roll on next thursday

My neighbour has recently had a cat replaced on her Mondeo because it rattled when cold. It took quite a time too to locate the source of the noise.

Mine makes exactly the same noise - sounds like very bad pinking for 30 seconds or so on cold and damp mornings. It's with the dealer now (also having the exhaust replaced as the mountings have cracked :eek: ) so I'll let you know if they find what it is.
