Hi there, Been lurking a while but now finally in a position to buy and been searching for a few weeks now for a good Avant Special Edition. Anyways I have my eye on 2 of the same year (07) and 1 is the petrol model and the other is diesel. I was leaning towards the diesel mainly down to MPG and almost put a deposit down yesterday until I started researching the car more and was shocked to see so many oil balancer shaft issues. It's already had the injectors changed due to the known issue with them but is the oil balancer shaft issue really a question of when rather than if? If it is that common and a certainty to fail why are so many owners out there sticking with them? So is this a no brainer and the petrol should be the only model to go for?
