This article describes changing the engine oil and filter in my Cayenne diesel. This procedure roughly follows GNAT's procedure over at 6Speedonline. The car requires an oil change every 5K miles. The diesel uses a special low ash oil to Porsche oil spec C30 or VW TDI oil 504 00 or 507 00. You'll need about 8 quarts. I buy two six packs of the Castrol VW TDI oil from Amazon. The Porsche oil filter is P/N 958 107 222 20 or Mahle OX420D and M14 x 20 x 1.5 drain plug crush washer ( ECS Tuning ES248399 ).




The steps I followed are:

1. Remove both parts of the under tray using a 10 mm socket and remove the engine cover making sure you get all four of the rubber cover bushings off.
   
2. Safely raise the car and put wooden blocks under the front wheels. Those with air suspension can do some tricky stuff to raise the car.
   
3. Wrap the cross brace under the oil pan with aluminum foil to keep it clean from oil drain
4.

5. Remove the oil filler cap to let the crankcase vent
   
6. Put a suitable drain pan under the drain plug and remove the drain plug. It takes a 6 mm allen. Make sure you are removing the engine drain plug and not the front differential drain plug ( 8 mm ) as GNAT says.
   
7. While the oil is draining go topside and crack open the oil filter housing and let it drain internally for a few minutes. The oil filter housing takes a 32 mm socket. The oil filter, oil filler cap and my added VW dip stick are shown above.
   
8. Remove the oil filter cap and old oil filter. Discard the old oil filter and oil filter cap O-ring. Install the new oil filter cap O-ring and the new filter into the cap. Lubricate the new O-ring with engine oil or some silicon grease. Notice the locating pin on the oil filter.
9.

10. The oil filter cap and new filter can now be re-installed on the engine. The oil filter locating pin fits into a hole in the engine oil filter housing shown below. The locating hole in the engine oil filter housing is at about the 2 o'clock position. Insert the new oil filter and cap with the locating pin at about 12 o'clock. The locating pin will mystically turn into the locating hole as you tighten the oil filter cap. Below is a photo of the empty oil filter housing with locating pin hole.
    
11. Tighten the oil filler housing using the 32 mm socket to about 23 ft/lbs
    
12. Using a fresh crush washer re-install the engine oil drain plug and tighten to 22 ft/lbs
    
13. Add 7 quarts of engine oil
    
14. Start the car and check for leaks. If no leaks then you can re-install the under trays. If you are missing under tray screws like I was the part number is N 91034501 which are a dealer item.
    
15. Lower the car and let it run to warm up the engine to check the oil electronically or use the dipstick I installed with no waiting. Make sure the car is level. The dipstick is VW P/N 059115611AM from Idparts.com or a VW dealer. The diesel is the only engine you can do this with regrettably. I added another quart of oil to bring the oil level to half way. Tighten the oil filler cap.
    
16. Re-install the engine cover
    
17. Using a Durametric or other tool reset the oil change maintenance interval. With the Durametric you select Instrument cluster and then select Commands and the three maintenance intervals will be displayed. Again you want to reset the oil change interval.

Nice post.

Funny how you wrap the crossmember. I don't mind much oil, that is, spilled drained oil from the drain getting on anything, those parts will last the longest from being protected from corrosion.

The techs at the dealership wash off the cross member with brake cleaner after draining the oil. I want things to be clean so I can inspect for the dreaded back of engine oil leak ( so far so good ).This was my first oil change after the end of the pre-paid maintenance plan.

aluminum foil is interesting.

I get my oil here: https://www.ecstuning.com/b-mobil1-p...iter/p0103469/ $7.99 per quart

Thanks much for the great writeup.. a copy of the DIY is being put in the Cayenne DIY subforum!

Thanks for the shout out

Nice touch with the foil. I like that idea

mcipseric

Thanks! More info about the dip stick please.

You just buy the VW dipstick and trim the handle so it fits under the engine cover then remove the dipstick tube cap that comes with our engines and you are in business. No more waiting for engine to warm up to get a level measurement.

Do you have the part number for the VW dipstick?

r553

The VW dipstick is P/N 059-115-611-AM which I purchased from idparts.com for $39.

How much did you have to shave off and its accuracy correlating to the digital measurement within the dash?

r553

When the actual dipstick reads full the electronic dipstick reads a bar down. Close enough.

Hahah ingenious!!
I wonder if cravenspeed will produce a non hacked up one that is accurate.
I wonder if this is possible on the 981

Thanks for posting. Just amazing that the only thing missing is the dipstick and we don't have to rely on the electronic sensing.
