Oil recommendations Exeo 2.0 TDI CJCC + Battery compartment water

Hi, Not had my EXEO long. Does anyone have any recommendations for VW 507 00 oil (eng code CJCC)?

I noticed that i also have the water ingress problem around the battery. Are there drain holes under the battery and brake servo ? I need to remove the battery but not keep on removing the servo. Any help would be appreciated.

After investigating last night i removed the battery to gain access to under the brake servo (pictured). There are 2 rubber drains grommets which allow water to drain, and also as i have read, to act as fume seals in the event of a leaky exhaust. The other grommet is under the battery which is harder to see. I cleared the holes with some plastic coated wire (probably an old clothes hanger) and flushed them out with the hose pipe. I'm glad i caught it when i did as the water wasn't far off drowning my ECU.
