Hi all, My 2007 2.0l Tdi 170 Bleeped at me on the way to work with oil Min which I only hope isn't the rocker cover issue after new injectors! Anyway car was serviced @ an independent prior to my purchase and is on Longlife plan currently. What Make/grade of oil do i need to top it up?? Got a Halfrauds/motor factors or a VW garage on my way home........... Cheers!
