Question about Skoda Octavia
It is 2011 model petrol
You didn't specify the # of cylinders or the make/model. Piston rings are replaceable, BUT without knowing how they were tested I'm speculating, They all should be around 90-100 psi. (Pounds per square inch) The only thing I would add, this is supposing the head gasket and valves are okay. Even with that the pressure in all the cylinders should all be within 20 psi of each other. A dealer would scare me. They may want to rebuid or replace the engine. Being a 2011, unless it has high mileage and no other problems, this can be caused by a bad oil pump. If you or someone you know can think of a garage that has rebuilt engines, see what they say. With the right knowledge and the right testing equipment, it is more likely that you can get an idea what all can be wrong. (Piston rings that are bad usually results in a blue color exaust.) Attached is an article from Popular Mechanics.

Yes piston rings can be replaced! Why have you been given this diagnosis? Is it burning oil? Is the compression low on a particular cylinder......loss of power?

Inspecting the piston rings requires that the engine be removed from the vehicle and disassembled. I don't know if this was done, but if it was, it sure was done quickly. Hope this helps and good luck.

If it needs rings, it probably needs a lot of other engine work, like a cylinder hone, or if it's out of spec, a bore, which means new pistons and on. You might look into a good remanufactured engine that comes with a warrantee if your has a ton of miles on it.

It can be time consuming and the end result may not be desirable if you haven't done it before.
--- The following is just a sample of what to do once the engine is torn down: Pistons and Connecting Rods
Damage to the engine can result if it is allowed to run with no oil pressure. Check the engine oil level to make sure that it is full. Check for any leaks and if found, repair the leaks before continuing. If there is still no indication of oil pressure, you may need to prime the system.
