Slight increase in oil level on dipstick;- Multivan TDI

[Silver Caravelle]

The manual for my 2008 model has a section on DPF. Note the DPF light has never come on in mine with a sooted up DPF. Regeneration has always occurred as expected. The DFP collapsing is apparently unusal. I don't even put myself in the category of being a timid driver. Even in the city, mine gets warmed up sufficiently! I actually notice regeneration after a long round trip of a few hours on country roads.
Regards,

Scott

DPF regen happened yesterday, so I know that is all working fine! I will monitor closely for any oil level increase after next oil change (soon).

As it is due for a fuel filter at 60k, hopefully this might sort out the slightly rough running/jerkiness at 1500 rpm. Otherwise further investigation needed.

Cheers, Scott

Hi Scott
I have just had 2 years of chasing this problem. Oil analysis proves it is diesel. VW warranty replaced tandem pump, complete cylinder head & no different. Then they reprogrammed the ECU & it was fixed for a while, now it's happened again.
Here's an experience that I found appropriate:

hi there , iv got a mazda 6 diesel 56 plate , my dpf light came on last year , checked my oil level and it was way above the max level but there is also a x marked on the dipstick further up and mine was above that . took mine to a independant mazda dealer he did a regeneration clean. reset the light job done. keep an eye on your oil level, as if you do only short journeys it clogs up the dpf filter which causes unburnt diesel to be dumped into your oil sump , if you look on your dip stick you have min and max then further up is a x mark , make sure you change your oil before it gets to this point as it can blow your engine. dont worry about your oil level rising its doing its job , taking your car out for a spin 45min or more once a week helps stop it rising to much , thrashing it dont help its getting the car up to working temp that helps burm the filters clean ,make sure you use fully synthetic oil aswell, hope this helps

I am doing an experiment to get rid of the STUPID "dpf"

just wondering what year model was yours to get this work done under warranty? did they pressure test the new tandem pump? i have learnt the hard way, just because they put a new tandem pump doesnt mean it works.

Built late 2007. 128kw BPC engine.
It was an 18 month old demo 1,880 km when I got it. Problem first occurred at 28,000 km just before warranty expired so they honored the repairs and responsibility for the problem.
We seem to have exhausted all possibilities which is why I have given up on VW solving the problem. I have to assume that their work is OK regarding the tandem pump, I don't think they pressure tested it, they replaced it first up.
The DPF has been removed now & ECU program modified to suit. I now need to do about 4,000 km to see if the diesel stops getting in the oil, that'l be about March next year.
500 km so far since the DPF delete & very happy - Heaps more power & looks like 20% better fuel consumption.
