Ford Mondeo / Vignale Club ; Mondeo Mk4 2.0TDCI Front end knocking / rattle Ford Model: S-Max 1.8 Tdci 06 & S-max 2.0 tdci 07 Ford Year: 2007 Hello all. im new to the site, a mechanic with 34 yrs experience but sometimes I get stumped and have to ask for suggestions/help. I recently pulled the gearbox out of my parents 2012 mk4 2.0l diesel manual estate, to primary fix an oil leak, which I suspected of being a failed rear crank seal, also the smell of clutch suggested that I’d probably be changing the clutch too, which turned out Ford Mondeo Mk4 (2007 - 2013) Drivetrain (Mk4 Mondeo) Does anyone know the correct spec for the gearbox oil for a MK4 Mondeo 2.0 TDCI Manual?
