Just tried to pull some oil out of the dipstick tube, was nigh on impossible. Should it come out quite easily or is there a chance the pipe I'm using is too fat and causing a vacuum?
Sounds like you need a thinner pipe. Should come out easily enough especially when warm.
Got a tiny bit out, must be causing a vacuum.

Hi, I am after some advice on the "reduce oil level visit workshop" warning, called out roadside assistance and the mechanic was very familiar with the problem, after removing 1.25 litres, he said the issue was either a faulty injector or with the regen process, the van is going in for a service very soon. When I spoke to the garage, they were very surprised at the amount that was taken out. Has anyone else experienced that amount taken out, and any thoughts on the cause?
Prior to this incident when did you last check the oil level? Reason I ask is some folk get theirs back from a service with too much oil and that eventually triggers the warning.
Mine gives the warning periodically and there's nothing wrong at all with the oil level.

Hello, yes mine had a bit more than yours removed by roadside assistance and the VW garage essentially refused to believe me when I told them! Haven’t had any issues with that particular warning since. However about 5 months after this my van kept going into limp mode and following further investigation it was found to have a faulty injector rail, which was replaced under warranty (thank god!). Since then no issues (fingers crossed) and that was about 6 months ago. VW commercial garage were particularly unhelpful with this and a number of other things. It’s clearly an ongoing problem with loads of the T6’s and they just don’t want to take ownership! Good luck.

I first got the warning after the first service. The VW garage that serviced it couldn't look at it for a couple of weeks, so another VW garage took some oil out, and I assumed it had been overfilled. This time, the warning came on near the end of a 200-mile trip, and I now believe it to be a regen problem. VW should have fitted a regen warning light. I am now aware of the problem, and after using the van, I check the rev counter before switching the engine off. Previously, when checking the oil level, as long as it wasn't low, I didn't think about it.

Thanks for all these messages.
I had the reduce oil level warning come on about 200 miles after a service. Checked oil level on dip stick and it was over the max line when cold.
Bought an oil suction gun from screwfix but the tube was too big to fit down and not long enough anyway. Got some longer and smaller bore pipe and attached it to the original but it wouldn't pull and oil even though I could see oil on the outer of the pipe.
Decided to buy a 12v oil extractor pump from amazon for £18 which worked a treat. Pumped it out even when the oil was stone cold.
Got it to half way on the dip stick when the engine was cold and so far after about 300 miles the warning hasn't come back on.

I take oil samples with a hose and a normal plastic syringe, it shouldn’t be difficult, obviously hot oil is less viscous and easier to draw off.
Mine was also pretty difficult to draw any oil up the tube, managed to get some out eventually and it's been fine since.
Ours started showing the same message, oil level was under max. Removed approx 500ml of oil so level is in the middle and regens are fine. Message still pops up so guessing a software problem? Now on 58k miles and only had this issue relatively recently. I guess its a trip to the dealers. Hopefully the warranty will sort
Mine still periodically lies through its teeth but I just ignore it now. The level is set mid-way between the max and min marks and never moves.
There is a software update but my ferreting around leads me to believe that it isnt successful very often.

An interesting update.
I serviced my van in early August and switched to a 507.00 compliant 5w/30.
I dutifully set the oil level halfway between the dipstick marks, and promptly forgot about it.
Driving back from my break today and it occurred to me I haven't had the warning si ce the oil change. It seems unlikely to me, yet the only difference is the fractionally heavier oil grade so I wonder if that has helped? It certainly runs more quietly on it, although Lord only knows what cheap and nasty grade had been in there before.

My t6.1 reduce oil light was on when dropped off delivery milage only multiple times at garage and updates soon as its out of warranty they want me to pay for diagnostic unbelievable to be honest california has covered 12500 miles only there remedy twice was to take oil out roll on 400 miles for mot engine management light came on while in for mot and there now saying oil temp sensor faulty oil pressure valve faulty cost with diagnostic and mot £1300 pounds my argument is multiple failed regenerations are causing this issue on short journeys
Dumping fuel into sump they are refusing to give good will so nxt option in sue them after a independent check on van
I'd have waved adios to it at that very moment.
Out oil level light still comes on but oil level is exactly the same. The joys of vw ownership
Autotrader, the damage is already done.
