My Cayenne maintenance book says for 10K miles "Also drain water from/replace fuel filter". I checked the Audi Q7 TDI forum and they said there is a drain plug on the filter housing, but I don't see a drain plug on the Cayenne housing. Has anyone figured this out yet? Replacing the filter itself looks pretty straight forward.

Nope no drain on the Porsche :censored:

I just did this and documented it over on 6spd. It's really a simple procedure and dealing with the diesel fuel is the worst part.

BTW the related PIWIS documents are very explicit that you need to keep the fuel from getting on the coolant lines.

Also you have no idea how high a Porsche dealerships overhead is, yes they charge a lot but there is a reason for that. If you do the work yourself and it goes wrong then you have no recourse, all the work performed at a Porsche dealer is guaranteed and they have to stand behind it.

Yes an oil change is a relatively easy job to do, and I'm not suggesting you aren't very capable of doing it, BUT how much is a new Porsche diesel engine. Also it is not the same engine as fitted to other cars in the VAG, despite what many people think.

Just my 2 cents

This is utter BS pure and simple. I'm sorry, but it is.

The engine is absolutely the same engine that is used in the T-Reg and Q7 TDIs here in the US. It's just ECU tweaks and a few other minor modifications (none that are going to impact oil changes).

Additionally as long as you follow Porsche's procedures and use approved parts (oil and filter), you still have your warranty if something goes wrong. They aren't going to replace your oil pan if you over torque the drain plug and strip it, but as long as you can show you used the correct oil and followed the correct procedures federal law prevents them from denying your warranty unless they can absolutely prove something you did was at fault.

There is also absolutely no excuse for the "overhead" Porsche dealers are charging for oil changes on these things. My area ranges from $375 to $675 for the 5k at the Porsche dealers. I did it myself for <$100 including a few tools I didn't have and just had the 10k oil change done at a VW dealer for a whopping $112! The only reason for Porsche dealers obscene prices is greed and people's stupidity to believe that a oil change on these cars is some how special.

Draining the water from the fuel filter (part of the 10k) is also an insanely easy process that requires a ~$90 tool (if you use the VAG extractor vs a generic one) and an hour if you go slow about it (now that I've done it 30 minutes is easily doable). I talked to one Porsche dealer and they wanted $300 for that on top of the $425 they wanted for the 10k oil change. The VW dealer would have done it for $120 (the procedure is apparently different than on the T-Reg and they weren't sure if they could still do it in 30 minutes).

I'm all for using and supporting your dealer, but not to the point of being absolutely robbed for the "privilege".

MFD said 17 degrees this morning which is the coldest mine has seen (yesterday was colder, but I didn't drive it). It actually started right up with no delay at all.

I've seen a few colder mornings, but not significantly so. I turn the key all the way every time and have never seen the glow plug light. I just get the "engine starts" message in the MFD and then it will start. The longest I had to wait was about 5 seconds (25-30 degrees out), but I've never had to turn the key multiple times.

I should have mine in a couple of months, but every time I've been in one I keep forgetting to look for a good place to mount the concealed display. Anyone have pics on where they put theirs?
