Dipstick Reading High

[Pau1GTI]

Hi Guys, I've read up on this as much as possible before posting this question.

Having checked my van hot and cold the oil level is above the maximum mark as per below


It's difficult to say if the oil is dragging up further as it's pulled out but I suspect it is definitely at at the highest mark at least.

The van was serviced 6k miles ago with filter and oil 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 the old oil away to be checked? If it's oil dilution, how much damage could this of caused in 6k miles? All seems fine with no lights, drives and sounds super smooth. With only 60k on the clock I'm a bit gutted with any premature wear this might of caused the engine as I plan on keeping it a long time.

Ps. Happy New Year

Genuine diesel dilution is unusual on these. Not unheard of, but the case for the prosecution is rarely proven.

Occam's Razor suggests the garage simply rammed up full up to the line.

They're happiest with the level about halfway between the lines, so you'll need to pump out c.500ml, perhaps a touch more.

From there you can monitor it, but I certainly wouldn't be flapping like John Inman in a semaphore class at this stage.

What year the van is?
What engine - the engine code?
Was it mentioned on receipt how many litres were billed/filled?

 

[Sasquatch]

What was billed and what was actually provided won't necessarily bear any relation to one another, particularly it it was pumped in rather than poured from a bottle(s).

It's a 2018 150 DSG. Thanks

 

[Pau1GTI]

Thanks chaps, I'm in no doubt I'm just worrying over nothing haha

No note of what was put in at the oil change.

It's a 2018 150

Not a known issue on T6 engines.

Oh that's good news then, is the t6.1 150 a different engine then?. It must of been those I saw having dilution issues.

Thanks

It depends, some early T6.1 had late T6 engines (MY19). Which interestingly means that MY18 T6 and MY19 T6 sometimes have different engines with same power output. It's the emission control system which makes the difference. Confusing - yes, indeed

The same happened with early T6 - early ones had late T5.1 engines (without AdBlue).

 

[Pau1GTI]

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 perhaps.

Thanks

Exactly that.

Hi Pau1GTI, did you get anywhere with this and what was the engine code of the car? Friend of mine having similar issues with his 2018 T6

 

[Badjamin]

There's an video about oil level creep that may be what you have happening?

I forget the code but it's the 150bhp euro 6.

I got the oil changed and don't turn the van off if it's doing a regen. I just let it idle until its finished. The oil level seems to be fine now. I hope that helps

I am sure it is quite common for the dealers to overfill the oil when changed. Mine also had the coolant way overfilled at last service.
When I did an "intermiate" oil change on mine I overfilled it slightly, and suspected that I would get the overfill warning, but I didn't.
I have since checked the oil level using live data from VCDS and it is showing 94mm (100mm is supposedly maximum), and hence not getting any warnings.

I read somewhere that the ECU does a recalibration when the oil is changed somehow, so suspect that is why the decrepancy between the dipstick and VCDS.

Has anyone seen the info on the recalibration? I think it is something like having ignition on when refilling, and mayby when resetting the change interval.

I will recheck at next oil change to see if things change and the dipstick and VCDS allign.

Quick update - I was rotating the tyres today, so decided to remove a little engine oil while the van was raised.
It is now reading just below the full on the dipstick and down to 74mm on VCDS (with engine off). With engine running it drops to 63mm on VCDS.
