My car has covered 36k from new. I had a misfire on Cylinder 1 which was first diagnosed as a coil pack. When this was changed it did not fix it so a compression test revealed there was a deeper problem. With the head off the piston had a piece missing from the top which looked like it had melted. Unfortunately this appears to have scarred the lining of the block. The independent garage have said I will need a replacement engine as the thickness of the block will not allow any rebore. I trust the garage and have inspected the engine. My beef is with VW , this is a DSG model and has not been thrashed by me since new. Will I have any claim against VW that you know off and is this a known problem? Thank you

Sorry to hear about your woes. If the car has a full VW service history from new then it's worth trying for a goodwill contribution, as a part-melted piston shouldn't happen in a car with electronic ignition, injection and anti-knock sensors etc.

If the car doesn't have a full VW history, I'd say you'd have next to no chance of any goodwill. It's simply the way car manufacturers are.

How badly scored is the bore? If its only the surface that's damaged you might get away with just a new piston.

I would contact VW as the pistons have been notorious for failing on these engines !

If the bore is heavily scored then an engineer can line bore and sleeve and the machine the bore back to a standard piston size, so shouldn't need a new block!

Thanks but the garage have said that the walls of the block are too thin for a rebore. Option of new block and extra labour or a recon engine. I'm pursuing the original dealer where I bought the car from new in the hope of some goodwill

It would seem deeply enough to be beyond repairing. The walls of the block look too thin to machine/ rebore. Thanks for your reply

First 3 years with VW of course but one major service in year 4 with an independent. It's with the independent one now in bits and I'm speaking to VW re a way forward. I'll be looking at consumer law re "fit for purpose" unless a reasonable goodwill gesture is made. Thanks for your reply
