Hi,

I'm looking to purchase a second hand RS3 and the cylinder compression tests revealed the following relative compression results (using cylinder 3 as the baseline)

Cylinder1 89%
Cylinder2 90%
Cylinder3 100%
Cylinder4 91%
Cylinder5 88%

The vehicle is almost 3 years old and with up to 12% lower compression in some cylinders, this is over the "normal" range of up to 10%

What could be the cause of this or are these results normal on a 8v RS3 for some reason?

Thanks
