I am giving up. Looks like these cars are only reliable for a short time.

Yip from the looks of it ... it would look as if the engine was abused ... I have not abused the car as I am the second owner, i am not going to finger point but it does seem as if the previous owner/s stuffed up the car, so far the stuff replaced points to an abused car.
Flywheel at 30000km, Rear diff at 59000km and now the engine .... what is next and the fact that the pistons are wobbling around in the sleeves tell's me this poor car was not well looked after .... either that or it's a defect parts.
If i did abuse the car i would own up but i have been a royal pain in the butt with this car and took it in for everything and never missed a service or even go over the km's.

I do feel for you jacques_RS3
Looks like you are picking up the pieces of an abused car, which unfortunately with these motors you are always more than likely too, once you start buying a used example, you’ve just no idea how the car has been treated by the first / second owner.........
I only hope that there is a warranty in place that will cover repairs and you can still enjoy the car at some point.

Detonation would break the ring lands as in the photo. Bad fuel?,too much timing? ,too much boost?.The ECU should have safeguards against this but if a sensor is broken ????

Too much fiddling by a previous owner ??
Who knows.

Is it the gudgeon pins that are loose? Had same problem with mine and Audi replaced the whole lot. Audi claimed they had never seen a rs 5 pot have that issue but it's looking like you have the same issue apart from mine hadn't got too blown piston point.The head atleast looks fine
I will try to get more pics of engine
I just need to find out the cause and then make sure that this gets sorted so it does not happen again.

Sorry mate
What is the mileage of the car/engine?
At what kms has it been serviced in the past?
Long life service?

Car is on 73000km's been serviced and always followed the service interval as indicated by the car, Km's or time which ever came first.
If Audi used correct OIL , I would not know, if they actually did a service and not just top up OIL , that I will not know.

Now while that is sorted i have a question for the experts or anyone that knows. The dealers sys the sleeve is fine that got damaged, but i don't agree as a normal hone job won't fix that as you can feel it. It's slighty there but you can feel it, and then if they rebore will there be oversized oem pistons for this car. My gut feel says no.

If you feel a ridge then honing to get rid of it will give too much clearance. Even an extra 0.002" will be way too much.As far as I`m aware Audi don`t do oversize pistons. A good machine shop however will be able to fit a thin wall sleeve I would have thought. It depends on the wall thickness.You could have that cylinder wall ultrasonically tested for thickness. If it`s too thin then it`s a rebore with aftermarket oversize pistons or a new block.

He says they will refit pistons but you will have to hone or lets say deglaze the sleeves for that matter to ensure that the new rings bed in properly..... or so i thought ?
I am not going to allow these guys to just put in new pistons without touching the block.

If you can feel the score marks when they refit new piston & rings it will lose compression & burn oil which is no good ☹
So what are they thinking !

Another good oil additive is LiquiMoly Ceratec. It reduces friction and along with LiquiMoly oil it works perfect.I spoke to well experienced mechanic. Piston 1 and 3 can be an issue if the wrong oil is used. Also as a precaution for us all we need to use a stronger coolant like water wetter and motul inulgel. If the engine is cool these piston rings wont give in and also after a hard drive, cruise for a bit then park the car off.
