Looking for a bit of advice. I have recently bought a2 07 2.0Tdi Quattro 170, and I think there is an issue with the injector seals. The injectors were done via the recall back in 2007, but there is quite a bit of blow by when the engine is cold.Is there a kit anyone can recommend that includes everything, the seals and bolts, etc for the BMN engine ?Also any advice for doing it ?thanks
