Thanks for the replies. What is concerning is that when I picked it up after its annual service at 27k kms it was noticeably quieter. Which indicates the oil is either diluting or breaking down.

I’ve got a December 2020 Vw t6.1 kombi. I purchased it when it was a year old so I don’t know what happened in its first year but I’ve had nothing but issues with the ‘reduce oil level, go to workshop’ warning for the past 2 years. I have been to my local Vw dealership a number of times and...

...little actual evidence of it. You might have enjoyed reading the myriad posts before slapping up the link. As stated, actual genuine oil dilution is almost unheard of on these, and the few that do arise are usually the result of a fault elsewhere such as a failed injector, etc, rather than a...

Good day all :) Hope you can help. I've owned my T6 LWB STN 4M 2l since August last year. When I purchased it it soon came up with an oil service notification (NOT warning light, see example image). I contacted the seller who provided evidence that it had an oil change not 2 months ago, but to...

...volume. This is not uncommon and it's not restricted to VW engines. Have a read of some of these threads for a better understanding of oil dilution; https://www.t6forum.com/search/2778894/?q=oil+dilution&o=relevance Oil on and around the oil filter housing wouldn't worry me too much, it's...

Oil dilution is far from unheard of in the T6; https://www.t6forum.com/search/5933240/?q=dilution&o=relevance

Thanks for that, makes sense now. Would you say I'm best to just do an oil/filter change to be safe, note the new oil level and monitor it. No need for oil tests etc if dilution issues isn't a big thing with the t6 engine. Most likely just been filled slightly too much during the last service...

...keep a close eye on my levels so I'm happy enough to ignore it. Nevertheless, it makes me wonder how many folk have suffered this fault and just happened to have a high oil level due to slipshod servicing and then went on to add two and two together and come up with "oil dilution" when it...

Exactly that.

Search with ‘oil level’, it’s a known issue, possibly due to fuel dilution. If it is due to fuel dilution you need to act to prevent engine damage.

This explains it better than I could… Oil dilution - diesel in oil and petrol in oil.

Just because the warning light doesn’t illuminate doesn’t make everything OK. If the oil is black / brown (no water emulsification) and the oil level is rising without anybody adding oil it is due to fuel dilution. Fuel dilution at just 2% will damage an engine / turbochargers. Have a search...

...change, truth is I never checked it after the service or up until now. So it might of been overfilled since then. Or it's the dreaded oil dilution from regens. I've booked it in immediately for an oil change and new filter, and it won't be driven until then. My question is, should I sent...

...a service I remove between 400 and 500 ml of oil through the dipstick tube to reduce it down to halfway. Initially I was worried about oil dilution so I sent a sample to Miller's for oil analysis, no worries from the results. I'm lucky my van doesn't use oil, I'm sure it's just oil...

It doesn't occur. Excessive dilution is all but unheard of on these. The warning messages are simply a case of garages brimming the oil to the top mark on the dipstick or even beyond. Sooner or later this upsets the sensor. Once the oil level is reduced to around the halfway mark the warning...

From reading this, I would certainly want to change the oil if it has been diluted by fuel. To not do so risks excessive engine wear by the sounds of it. So why are dealers just siphoning off the excess? @Ian Watt, what did VW assist say?

Welcome to the Forum, there's plenty on here about oil dilution and DPF issues!

Kind of what I’m doing currently to be honest. Pre-empting at the moment as my regen frequency is the biggest red flag indicating it’s getting blocked. But such frequent regens also bring their own problems right? Like a rather unreasonable MPG and oil dilution?

Have a Search with ‘dilution’. Plenty of content on the Forum. If your oil level is rising without anybody adding oil there are two possibilities: 1. Coolant contamination - emulsified oil, obvious. 2. Fuel dilution - not obvious at all and with a 2% diesel contamination limit before accelerated...
