I freaked out the first time i went the rounds with the dipstick on my car... WTF!!!

these cars are just plain different!!! no idea why the dipstick cant even be normal.

why the heck redesign a dang dipstick? maybe its not intentional by VW to have a retarded dipstick on the V10, but I wouldnt be surprised if they had to do some weird crap to make it fit or something.

every time i dip it I get a higher reading until it reaches the actual reading.. haha ive even had it in and out of there 5 times or more... i guess its fun after a while.

 

anyone know why this is???

+1 - damdest thing I ever saw. Takes 5+ dips to get any reading at all some times.

 

by this time in the engineering world and on such type vehicle, an electronic oil measuring feature should be involved.

many years back Porsche had it on their vehicles and was told by my Porsche tech while I owned my 2000 Boxster "S", that the electronic measurement was more accurate than the physical dip sticking method

Curious to know if Cayenne fleet is so equipped and I wonder whether there is a possible hack to facilitate electronic measuring

 

What is the correct reading on the dip stick?

It does have an electonic level check as such. There is a warning that oil is low on the MFD when the level gets to Minimum, John

 

an "oil at minimum" is a useless means for maintaining a proper level

this warning should be substituted for an electronic bar scale meter like in any current Bimmer or late model Porsche

I'm gonna bet you that countless v10 owners have over filled due to the stupid dip dip dip stick read check measuring and we all know what over filling does to cats and other emission related devices

 

Must admit only way I've found to check reliably is park dead level, start motor, run 5 - 10 secs, turn off, wait 30-60 secs, dip, wipe, dip. Normally any extra dips after that are the same but usually do a few more. A bit like why the Irish use 2 condoms ...... to be sure, to be sure. I got caught once with the level reading below minimum, added 500ml checked again and over full. Syphoned out 400ml and level perfect????!!!?!?!? Also checked a few thousand km after a service and found over full. Took the cover off the top of motor and found oil weeping around the PCV hose area. John

 

Checking Oil Level in Touareg V10 TDI

The Touareg V10 TDI dipstick often does not show the correct oil level. Others have noted a "dip-wipe" sequence is needed three to five times before the level is shown correctly. The first reading often shows no oil at all and might tempt you to wrongly add oil.

I think the reason for all this is that the dip tube that extends down into the engine oil reservoir is substantially longer than the dipstick. Normally the level in the dip tube should be the same as the level in the engine. However, when the engine is running a fairly large volume of oil is pumped up into the engine, various oil lines, oil cooler, etc. When you park the car and stop the engine, this oil drains back into the engine, raising the oil level in the oil reservoir back up. The level should equalize into the dip tube, but the dipstick seals the open end at the top--you can see a small O-ring that fits tightly into the tube. Since the top is sealed, the rising oil level in the tube compresses the air column and can only rise so far, but not far enough to reach the bottom of the dipstick. So the dipstick shows no oil.

The solution is to pull the dipstick out, breaking the seal and allowing the oil to equalize into the dip tube. This may take anywhere from 15 to 60 seconds or even longer depending on the oil and the temperature. The "dip-wipe" sequence is essentially providing this time. It may even help a bit by "pumping" the air column. After this the levels are equalized and you get a correct reading.

You can test this by pulling the dipstick out just slightly when you stop the car, just enough that the O-ring doesn't seal. When you come back later and push the dipstick in fully you will get a correct reading the first time.

I can't see the inside details of the engine, so I am really guessing at all this, but it sure seems to fit the facts.

Hi Joyler
i think you have nailed it imho i totally agree with these facts about the vacumn in the dipstick tube and the fact that it takes a few minutes for the oil distributed around the internals surfaces of the engine to all drain back into the sump in my 50yrs of checking oil levels with a dipstick that has always been the way to do it wait a while then check it
Basic common sense

 

I check in the morning before I start the car.

 

Holy Sh*T. What? This is screwed up. I think I've been overfilling and wondering where my oil keeps going. Did I miss this in the FAQ? I am Yosemite Sam cursing right now. Check oil - nothing - add oil (over fill) - check oil (LOTS) - probably burn extra oil cause - it's overfilled. Check oil in a week - nope it shows dry. Rinse and Repeat. Goddammit.

 

You do know you have to wait a while after removing the dipstick for the level to rise? Maybe an hour even.

 

I've had it years and nope. I wonder if part of the cluster f*** of my cam replacement they lost the dipstick and replaced it? New o-ring might contribute to this "new result". I have NEVER had issues and I checked my oil frequently - then - suddenly this weird ****. Which - it seems everyone already knows about?
They quoted me 2800 to replace the turbos - the ones I had just had rebuilt while the engine is out. I knew they were guessing - shocker. But taking it elsewhere to the "VW/Porche Specialists" was no better.

 

I wonder if the tip of your original dipstick might have broken off, a known issue, and the replacement is bumping into the old one down in there.

 

If a dipstick had broken off it would fall into the sump

 

Not necessarily!

There have been quite a few cases recorded over the years on here and elsewhere of the bottom of the V10 dipstick snspping off and subsequently being successfully recovered by putting heat shrink tubing on the long part, inserting it carefully then running the engine up to temperature before withdrawing a whole-again dipstick!

 

On my v6 the dipstick tube doesnt have a bottom in it because i slipped a length of stainless steel wire down it and it went right down without any restriction or the use of force
