Hi I have a 2016 Skoda Superb that I have been told needs a new timing chain as it is stretched. I understood these to be 'lifetime' and rarely need replacing? Has anyone else had the same issue? I have also been told that there is a 'plunger' by the chain that if replaced may assist in tightening the chain.  any advise would be appreciated as this is potentially a large repair bill...

Thank you 

How’s the service history for the car?

What fault are you experiencing?

How was the chain stretch checked and what were the findings?

What engine are we talking about?

Whats the car mileage?

Hi, it’s a 2016, 2 litre petrol, 96k miles fsh.

it was picked up by a garage that we bought from running diagnostics as it has been sluggish to drive.

thanks
