Hello there,

 

I`m writing to you guys hoping that you can help me get to the bottom of this, as I`m on nearly the edgee...

 

I have a problem with my Skoda Fabia 2008, 1.2 HTP, 60 CP. Sometimes, after starting up the engine, the acceleration oscillates and the engine starts making these weird clunky sounds. After several opinions from different mechanics (including Skoda Service) none can really identify the real problem, as it does not show up with any errors while tested. I had a few suggestions:

 

- Replace the fuel filter (work in progress)

- Car Software Update (scheduled for tomorrow)

 

I managed to record it while happening, and upload it onto YT. If you wish, you can take a look for yourself, here.

 

Any help or suggestion is highly appreciated.

 

Thank you very much.

...The VERY obvious first check is to see you have oil!

It was checked, of course.

Can you try again now? Thanks.

Hello there

the noise is appalling! - I suspect that you have recorded the noise from a very close proximity - that clouds the issue.

First observations are as follows...

1 - The noise overall sounds very top ended, IE the valve gear is very noisy (possibly the closeness of the recording emphasises this.)

2 - The big concern is that when the clunk happens, it is almost like there is a full mechanical stop/lock taking place causing almost a stall situation, that just recovers due to the momentum of the engine - hence the movement in the engine within the frame.

3 - This is a curious one in that it is just possible that a momentary ignition failure happens with an almost instant recovery.

I would be very concerned at the serious mechanical CLUNK which would make me immediately look at the chain/tensioner situation as a first action.

Fuel filter and software is not going to overcome this problem.

Please let us know the mileage of this car, and what repair work has been done that you know of.

Finally I am appalled that Skoda (supposedly ) trained staff have been (it seems) unable to give you a  definitive opinion/answer.

Keep us in the picture, and I honestly would not be driving your car until it is sorted..
