I have a Mk6 Golf GTi, 2 years old with 24,000km on the clock. It has been using oil since day 1 – averaging around 1L every 18,000 – 20,000 km.

The dealer recently did the “oil consumption test”, confirmed it consumed 610mL in 980km which is outside acceptable limits. They have ordered new pistons and piston rings.

Has anyone had their pistons and rings replaced due to excessive oil consumption? If so, did that solve the oil consumption problem?

This implies the pistons or the rings or the cylinder bores were out of spec / out of tolerance in the first place. I assume they will check the bores and hone them if necessary?
