Hi Guys,

I recently took the delivery of my OCtavia II VRS 2.0T 200PS. It is a second hand car with 100,000 KM on board. When the car is stationary and engine freely revs at 1000 RPM it makes a clattering sound like diesel. When I start driving it, it stays and increases with the speed. Is it normal or some problem with the engine. Kindly help

I don't the 2.0T in detail, but is the noise rev dependent and does it still occur in neutral? If it does, it could be something like the valve timing adjustment, the cam shaft chain or the oil/water pump. Worth getting it checked out all the same though. Rev dependent clatters should always be diagnosed ASAP.

When it is in neutral and gas pedal unpressed it makes more clattering sound like diesel and you could mistakenly judge it as diesel engine. While moving around the town it stays the same but at highway cruising speed it is less noticeable because tyre roar and other noises itruding into the cabin

It could well be a chain them of some sort because if the engine is not under load, its likely whatever chain it is wouldn't be under much load either so would chatter more. Could be a fault tensioner in something. It may well be nothing major at all (could be something as simple as some debris catching on something) but I would say definitely get it checked out. It should still be under warranty right?

100,000KM ? not sure on Miles conversion but that would be out of warranty i think :confused:

yeah it is not under warranty any more

Today I checked it in the morning that clattering sound disappeared when I started in the morning, at the idle speed and it start coming after 5 minutes when the temperature gauge raised to middle. As I was driving it more, it kept on increasing and then at idle speed also.

What condition is the oil in? I've heard some TFSI engines sound pretty rough, and an oil change cured the problem.

I went to two garages yesterday. Skoda garage says it is nothing very serious and could be fixed while servicing . The second garage (some ordinary garage) says one of the cylinder is getting limited supply of fuel because of faulty fuel pump. It put me under suspicion. I am now going to AMAG today to get it checked. I dont know who should I trust?

Maybe one of the injectors is clogged.

today they checked the four cyliders separately and all were workinf fine and then they change the fuel pump but all in vain. Noise is still coming. Now they will contact the skoda schweiz to know about the problem. My seller says this noise was present from day one when he bought the car. But I checked the other new skoda RS they dont produce such clattering diesel like sound. The garage who sold this car to my seller saying it is very normal. And my garage says it is not normal and will increase with time. I am in a catch 22 situation now. My garage is asking about 1000 pounds to check it further as they dont know where the problem is.

what they have done so far.

1) Topped it with engine oil

2) All cylinders are working fine, they checked it one by one

3) They changed the fuel pump.

no solution to it.

Are they hydraulic tappets on those? Maybe sticky tappets?

Maybe a good engine flush and then good quality oil after.

Mine makes a clatter when idling, but i think its clutch related, when i put the clutch peddle all the way in and lift it a bit the clatter goes, it also disappears when im on the move

The vRS engine does clatter a lot when cold and at idle, but should improve when hot....

it could be tappets also. good point to be raised.

no it is not clutch related. Clutch is heavier and smooth and does not affect the clattering.

The vRS engine does clatter a lot when cold and at idle, but should improve when hot....

mine is totally opposite. When cold engine is silky smooth and after five minutes of ideal running, when temperature gauge start going up, it start making clattering noise and when temperature gauge is exactly in the middle it makes maximum clattering noise.

Maybe one of the injectors is clogged.

if injector is clogged board computer should complain it immeadiately.

New information:

1) Seller and his garage(skoda garage) says it was making this noise from 0 KM and day one and is quite normal.

2) My garage(again skoda garage in different city ) says it is not normal and will increase with time and some day it will be intolerable. But he could not locate in the engine from where it is coming. It spreads in the whole engine compartment.

3) My garage will contact main Skoda to know more about this problem. I am waiting for service history book which my seller did not give me on delivery. Service book was lying in the seller's garage.

4) I checked on other vrs this sound was not there and engine was fluid smooth. I love that.

if injector is clogged board computer should complain it immeadiately.

There have been cases where,surprisingly enough,the board computer didn't complain about anything.

I don,t think a petrol injector will give you a clatter unlike a diesel one which would give this kind of noise.The oil is thickest when cold so would be quiet on idle but when hot it thins out so would show up the symptons you describe.i think its head related so would be checking the hydraulic lifters.Possible re-shim?

Good luck

Or low oil press:eek:ure

Yes could well be that too.I don,t if those engines have an oil pressure relief valve fitted in the oil pump?

Thanks for your post, could you kindly tell me what are hydraulic lifters and where they are located. And what is re- shim? So that I could talk to my garage.

I meant hydraulic tappets or lifters as they are known too.The shims are of a certain thickness that keeps the tappets within there tolerances hence quiet top end.
