Hi, I eventually had the cams replaced on my A6 by a local mechanic but since then I have had a slight oil leak from the point where the wire goes through to connect to the injector. The mechanic told me the can kit I supplied didn't have a grommet for this wire and he sealed it the best he could.
Having a look at this useful thread How2: 2.5 TDI Injector replacement. I was thinking of having a go myself but before I start, does anyone know if this wire runs under the rocker cover gasket and if a grommet is required? If so, where I can get one ahead of time.
