9000RPM

Hey guys,

Just wanted to share this tool I found to manually check our 958 base engine oil level. I was surprised when I did the oil change and found out that there was no dipstick last August. Since our base cayenne 958s use the VW 3.6 engine, there is a special tool used by VW Techs to manually check the engine oil level instead of driving it for 5+ miles for the computer to register.

Part number is T40178. If you google around, they can be bought for about $25.00.

Here are some the instructions on how to use this tool:




As always, I will post a picture of it when mine arrives in the mail.

I wouldn't be surprised if Porsche techs use this to manually check the oil level in the bigger engines. Since it has an adjustable slide, it's just a matter of knowing where to set the slide at. Maybe someone who has access to PIWIS can chime in if it shows this kind of information? There's no way a tech is going to drive for 5+ miles after every oil change he/she does.

PIWIS2 has a routine that once it runs while the engine is idle (takes a minute or two) it will tell you exactly how much to add to get to max level.

Where is the oil dipstick tube??

I wasn't aware of this "improvement" on the 958. I think the guy who decided to delete the dip stick is a dip stick.

I took a look at the data on oil from the ICarScan - and found a readout of oil-level: It's under the oil-pressure data section on the engine DME.

"0110 Engine oil level sensor 3.15 inch" - I imagine this corresponds to some spec that the Porsche techs get with the PIWIS or is used by the PIWIS to tell the tech how much oil to add.

Just a WAG - max level might be 4" - since I'm down one-bar from full on the dash display, and each bar is ~250cc's. In that case it would be pretty easy to calculate how much oil to add (4"-3.15"=.85", .85 x250cc = 212cc ? Of course I'm sure they didn't use inches in their calculation... so I might just be full of fudge. I'll have to switch it to metric next time I hook it up.

PIWIS tells you to the tenth of the liter how much to add to get to the full level - no measurements in length given.

Thanks for sharing the dip stick part number. I bought one of this to check oil level before changing oil on our 2012 Cayenne V6 3.6. Interestingly, it barely registered on the dipstick (only a little oil on end of the stick). The oil level sensor on the instrument cluster shows oil at full (4 bars and green). This didn't make sense based on 9000RPM's instructions.

I went ahead and change it anyway (time to change anyway and dealer wants $270 for oil change!). I kept track of how much was drained. It was a little over 6.5 quarts. I put in a little over 6.5 quarts (account for lost from oil filter housing, oil filter, etc). After 20+ miles, the oil sensor finally registered to be full (4 bars and green).

The dipstick still doesn't register much, a little oil at end of stick. I am getting conflicting info between dipstick and oil level sensor! Is there something wrong with my oil level sensor? I know I have at least 6.5 quarts of oil in there. The manual calls for 7.29 quarts (I think, don't have the manual in front of me right now). I must have done something incorrectly...

2016 Porsche Cayenne 958 Base V6 - you can put a real dip stick in this engine.

VW sold a V6 Touareg in 2016, and guess what? It came with a dipstick.
If you look at the Porsche Cayenne, driver's side, middle of the plastic manifold cover, there is a plastic peg facing straight up, about 1 1/4" - about 2 1/2" total length when you yank it out.
This is the 'Dip stick Locking Pin', VW part No. 079115418B.
Pull this out, and insert VW part No. 03H115607B, a real dip stick!!
I ordered mine from the nearby VW dealer, who shipped it to me with no shipping cost, for $29.
Examples on Amazon can be found for <$20.

Bick - the part you gave is for just the dipstick. How do you use that without the dip-stick tube (that fits in places of the plug, and the dipstick goes into it, guided down to the sump)? The tube seems to be more expensive - around $58..

deilenberger

The latest Porsche iCarScan software also tells you in liters (tenths) and %. It seems quite accurate.

Ok, so you have the stick. Where ya gonna put it. Idon'tknow where there is a tube on the car.

PTEC

The dipstick tube is installed from the factory on the 2011 and newer vr6s, all you need is the dipstick from the earlier 2008-2010 vr6 cayenne and you can measure you oil accurately without having to rely on the instrument cluster.

deilenberger

Thanks for letting us know.. that's very useful info!

Just want to confirm that this is only applicable to V6 and not the turbo V8?

garrett376

Are people having rampant problems with the instrument cluster measurement failing to make this necessary?
