Hello,
Apologies if this has been asked before (tried the search) I have a couple of questions about my 15 reg SDV6. Noticing the engine seems loud between 2-3k RPM (compared to another D4 i have driven) and have steam/smoke coming out of the oil filler cap. Is this the start of the engine failing? Any other early warnings they may give?
Thanks [/b]

If you do a search on "D4 engine failure" you'll have hours of bedtime reading designed to give you nightmares

Or try a more specific search using some key words from your post... I want to see the sweets before I get into your windowless van... I'm not stupid!

How is the coolant tank looking?
Try capturing some of the smoke/steam ... what happens when it condenses?
No "emulsion" when you look in the oil filler cap? .

Coolant tank is fine, same with the oil filler. Still need to capture some of the smoke/steam but didn't notice anything dripping off the cap when holding it there.
Want to add as well I have only owned the car for a couple of months so this noise could have been there for a long time.

Is the smoke/steam coming from the oil filler cap with it fitted - and is the seal on it OK?
If it's coming from it with it not fitted, that's pretty normal TBH.

No only when removed, the only reason I was concerned was because a similar age/millage one wasn't doing it plus there is the general loudness of my engine which the other does not have.

All engines 'breathe' - there may be a blockage or restriction in the oil separator which is causing a higher than normal crankcase pressure, if you have diagnostics, check the cylinder balance values, otherwise, a compression check plus cylinder leakage check would be the first steps to get a 'current state' measurement.
Despite being the 'same' vehicle, there is a variance in performance, can you try another vehicle to see if the difference is the same or more/less than the previous experience? It's not easy to diagnose an actual problem vs. a perceived problem with a sample of 1:1
