Hi all I have a 1.9tdi Quattro with a gearbox oil leak 6 speed its not serious but needs attending . I have steamed it all down and checked where it's source is and seems to be coming from the backend of the box where it looks like it can be split. Am I right in thinking this is the transfer box and is it gona be a hard job. If anyone can help It would be greatly appreciated and if it is a specialist job is their any additive you could suggest that can seal up leaks if it's gona be crazy exspensive thanks .
