When I replaced the timing belt on my 2.7, I went ahead and upgraded the oil pump since I’d heard about potential failures.

and for the 3.0, the oil pump doesn’t seem to have the same reputation for issues, so it might not be necessary unless there’s specific wear or you’re already tearing things apart. On another note, I replaced a couple of seals with hnbr rubber ones during the process because they’re great for handling the heat and pressure in these engines.

When I bought my D3 as part of a preservice check the oil pump was replaced as well as the engine belts. All went well except for an early failure of the crankshaft seal. I subsequently bought the seal type recommended on this forum and paid particular attention to it's installation, making a special tool to set the seal position - no problems since.

Oil pump is only a requirement on early 2.7's. The later 2.7's in both the D3 and prior to MY12 D4 TDV6 range are factory fitted with the upgraded oil pump.

Only the very late D3 got the upgraded pump so its worth checking the serial number to confirm before dismissing it and having an engine failure.
My 07 built MY08 had the old pump and crapped itself.

Likewise my Sep 07 build MY08 had the old pump. I upgraded at the first belt change in 2013 then changed again at second belt change around 2021 to the latest and greatest for oil pressure peace of mind.

Mine also. Upgraded in 2017.
