Guys my e320cdi became really sluggish the last couple of months. Though it was the MAF so changed it but to no avail. In the end had to to a garage with diagnostics. They said that they couldnt contact either engine or gearbox ecus and when they opened them up they were filled with oil. Allegedly took almost a pint of gear oil out! Ive been told that the oild has wicked it way from the gearbox up the cables, and they say it has to go to mercedes for repair. Has anyone had anything similar? If so what are my options? and what costs are expected?
