Had the car checked today as it’s making these noises under load. Of course it wouldn’t make the noise for the mechanic and all the belts run fine at idle, although you can’t check the timing belt by sight, and all suspension parts seem okay. So I’m no nearer finding out what it is. 

 

Initially suspected the exhaust heat shield but that seems fine also. Thought about a snapped spring also but ruled that out. 

 

Does anyone one have any ideas?

 

The car car has been faultless for

130k until now. 

 

Its a 2015 1.6 CR TDi. 

 

 

Can either yourself or a passenger hear where said noise is coming from?

Might be dual mass flywheel getting ready to fail.

No vibration through the gearstick at all. Clutch is still silky smooth with the usual MK3 bearing noise. 

 

The noise is intermittent. As soon as the car stops it takes 5 mins of driving or so for it to start again. 

 

I’m beginning to think it’s suspension related.

It “feels” like the centre front of the engine. 

Quick update.

 

Took the car to another mechanic, one who lives and breathes Octavias as he runs a few as taxis and has done for 15 years.

 

He heard the noise but couldn't find a single thing wrong with the car apart from letting me know it will need new front shock absorbers in the not too distant future.

 

He says it sounds like something is loose and rattling and will have another look on Thursday when it is in having its cambelt and water pump changed. It's definately not coming from the engine area as I heard it from outside the car.

 

So until something actually breaks I won't know what it is. It's intermittent and not particularly loud atm anyway.

I thought I’d better update this post. 
 

I had the timing belt, ancillary belt and water pump replaced and the noise vanished. So it was a belt issue. 

Did it have a Gates tensioner on it by any chance?
