Hi all.

 

I have a 2005 Skoda Octavia Mk II 1.9 TDI (105PS) with 95,000 Miles. Yesterday a incredibly loud noise started whenever the engine is at idle speed (no matter what gear/actual speed) that disappears when any throttle is given and I can feel it in the clutch pedal when it is fully depressed. The noise itself isn't quite a grinding sound but more like a knocking sound (I will be able to link a video tomorrow) and I believe it may be the Dual Mass Flywheel that has failed.

 

I have a few questions if that is the case ^:

1. How much do you think it would cost to replace this part and is it labour intensive?
2. Would it be better or cheaper to replace it with a Single Mass Flywheel? 
3. Is this noise even the flywheel?

 

Any replies are appreciated and I am happy to give more information if needed.

Thanks.

I have now had time to record a video showing the noise:

 

I can't help with diagnosis, but if it IS the flywheel, the answer to your questions is as follows:

1. You're looking at about £500 - 700 - get your clutch done at the same time as it's the same labour; no point in only getting one done becuase when the other goes you'll have to pay for that same labour over again.

2. If your car has a 5-speed gearbox, I think you're probably sensible swapping to a SingleMF. If it's a 6-speed, the SMF is not compatible.

That video sounds exactly like my car. I have the 6-speed gearbox so won't be converting to SMF. The car has done 190k and as far as I'm aware this will be the first time the flywheel and clutch will be changed. The previous owner kept receipts for everything, including lightbulbs. Luckily it was well looked after, all the services when needed.

 

I actually just booked my car in today to get the flywheel and clutch done. I also need a turbo but due to cost, that has to wait.

The most expensive quote I received for clutch, flywheel & turbo was £2600. The cheapest (using a recon turbo) is £1100 which is where I have booked it into. Seems a nice small family garage, never had a bad vibe from them. But as I said, turbo will have to wait so maybe half roughly that price for clutch and flywheel.

 

Also I'd like to add, that noise has been going on for over 1 and a half years on my car. It HAS gotten worse but still no major issue ( I hope). I would have liked to sort it sooner but money.

When in 6th and 5th gear at a particular rev the car would vibrate at the back which I was told is the flywheel causing a vibration to run rearwards. It now happens in 4th and sometimes 3rd but only within a given rev/speed range. As long as it lasts until my appointment

adding info

Hi all, just to let you know that I had the Clutch & Flywheel replaced and the noise has now gone and the car is a lot smoother to drive.

That's nice to hear. I just posted the following in the thread

Thanks again all.

Well, this is a bit of an unusual situation....

I took the car into the garage today and left it with them. The reason for the timescale estimate was because they had not initially diagnosed the faults so they wanted time to check over the car, then order parts as/when needed then fit etc.

 

A bit of the back story:  The first garage I took the car to a long time ago could not diagnose the very loud rumbling noise coming from the rear of the car (sounding over the rear axle) when in 5th and 6th gear and only at a certain rev/speed range. I started reading through this & other forums to get some information as to what it may be. After reading, I guestimated it could be the prop shaft, a potentially very expensive fix.

 

To be certain, I took the car to the VAG specialist in the nearest town and left it with them. They phoned me later that day and said the noise is a buggered flywheel which is causing the vibration to run to the back of the car and be heard there. They also said the turbo is on the way out (turbo whine which I could hear a little of anyway, but only a little). They pointed out that the tester knew straight away about the flywheel as he could feel it in the clutch pedal. I was extrememley surprised but hey, they are 'specialists'. Thinking back now I don't think they done anything other than take of for a quick spin and then come back with the conclusion of a flyweel. For clutch, flywheel & turbo, this garage quoted £2600, almost as much as I paid for the car a couple years ago. Needless to say I was pretty shocked and feeling, oh ffs not another effing car!

 

Fast forward to the garage I left it at today. The people are one of our customers for the business I work for and I just queried out of curiosity many months ago about these potential problems. After chatting to them & feeling quite reassured by their manner I asked them to give me a quote for the above work which came back at roughly £1100 but using a recon turbo instead of new. There was a glimmer of hope that I could actually save the car. It is probably my favourite car I've had & it has been well looked after by the previous owner.

So, the garage phoned me back today to say they had removed the starter motor to get access to the clutch and could see that it looks in exceedingly good condition given it's done 190k. They think it may have been changed a few 10k's ago but judging from the massive folder of receipts I have from previous owner (who even kept lightbulb receipts from skoda garage) I can't see any info about a clutch change. They could hear the rumble when they test drove it. They also said they checked the propshaft bearings and everything seems fine. They also said there is only a very light misting of oil around the turbo and certainly nothing that indicates it's mileage. There is only the very tiny whine which they say is nothing to worry about. In short they are quite impressed by the condition.

 

So, I was passing through the area with the works van today and I popped into see if any further development. The owner said he has a suspicion that one of the engine mounts is actually needing changed and that could be the cause of the vibration felt at the back whilst in a particular rev/speed range. He said he suspects this as a similiar issue had occured recently with another car he was working on. He phoned up the VW group who stated that one mount in particular is prone to going so my garage ordered the part from Euro car parts (cheaper) which is being delivered & fitted tomorrow.

I have my doubts that it could only be a mount but I trust these people. They seem genuine, nice and fair.

If it DOES turn out to just be an engine mount then damn, am I going to be one very happy person! And if it is, then wtf to that VAG specialist garage! But, I shall wait and see!

 

Fingers crossed
