My '05 TT with 6.7K miles has used 9 qts. of Mobil 1 to date. The 1st 4K miles, it averaged 1 qt. per 1K miles. This increased to 1 qt. per .5K miles from 4K miles till present. After discussing this several times with the dealer, and having to listen to the "it is a characteristic of the vehicle" line from both the dealer and PCNA, they finally agreed to do an oil consumption monitoring program.

I took my well detailed vehicle in to the dealer, and received a dirty Ford Explorer with some elses drinks still sitting in the cup holders. The vehicle was clearly used by chain smokers, as just sitting in the car for 10-15 minutes caused the smoke odor to transfer to my clothes and hair.

The dealer checked for leaks, and of course there were none. If there were, I would have noticed oil on my garage floor. I had explained this to the dealer, but I realize they have to check. They logged the miles, as well as the oil level, and asked me to return after driving approximately 1K miles, so that they could log the oil level again.

What concerns me is that they can not tell me what will happen once they verify that the vehicle is consuming excessive oil. If this level of consumption were truely "characteristic of the vehicle", then everyone with a TT would experience it, not just some of us. Although I am willing to do my part in this, I am not very optimistic of the outcome, as several other posters have written about similiar oil consumption, and have not gotten anywhere with it.

 

That ain't normal....I barley used 1/2 qt after my first 3500 miles. Be nice the dealer. Tell them you want a new one if they can't resolve this...If not, get a lawyer and lemon it...

 

This has been my contention from day one, that using this much oil is not normal, otherwise all owners would experience it. I am trying to work with the dealer, but am not hopeful, since their initial reaction was not "you better get the car in, something must be wrong", but rather, "this is characteristic of the vehicle."

The shame of the thing is that the TT performs like no other SUV I ever driven. The responsiveness and handling remind me much more of the '01 Mustang Cobra I had for 6 short months before it was stolen. Other than the Cobra, I have driven SUVs for the past 10 years since I need the interior space, as well as the ability not to get stuck in snow. The TT gives me the perfect balance between functionality and the "wow" factor. If only Porsche could work out this issue, and the others which plague other posters, they would really have a winner.

 

Best of luck getting things resolved. It is too bad there is such varying quality control issues with the Cayenne. I guess you have to be lucky. On the S I had before my turbo, had the steering wheel vibration thing going on w/ a variety of other recalls and fixes... My point is, from a SUV standpoint, there is no other substitute...Any of the others...ie BMW, Mercedes or RR would be a huge disappointment in comparison to the satisfaction I get with this truck, but eveyone has a breaking point. When you spend 100K on a truck, YOU deserve some satisfaction and if the dealer or Porsche NA cannot provide it, a good lawyer can...

 

Amen to that. Unfortunately, Porsche gets away with what they do because of the acceptance of this attitutde by a significant number of their owners. Immediately prior to the TT, I had a Lexus RX300. Other than scheduled maintenance, the RX300 spent a day at the dealer. I was always treated like a celebrity when I brought the car in, always got a sparkling Lexus as a loaner, and never had ANY issues with the car. And the sad thing is the Lexus was less than 1/2 the cost of the Cayenne.

Anyhow, I will keep everyone updated as to how the oil consumption goes.

 

i put in the 8th quart at 8k miles and have gotten the "that's normal" line of schit from PCNA re: both the oil and the 6k miles my conservative driving wife (4 months was pregnant and 4 with infant) got out of the first set of tires. hey, maybe one of these days they'll figure out the life threatening hesiation. at least the vibration (bad enough you want to take your hands off the wheel) present since the day we bought the car new ("must be the roads because everything is in spec") appears gone (though it's only been driven 20 miles since) after tire replacement yesterday.

 

Just had my engine replaced due to excess oil consumption, so I know what you are going through. Believe me PCNA did not want to pay for it and the "documenting" took 8 months(I don't drive that much)

 

Maybe there is hope for me. Sorry to hear about your troubles, but glad that someone else refused to accept this "characteristic of the vehicle" nonsense.

 

TKDKid,

What dealer are you using out of curriosity who told you it was normal oil consumption until you pushed the issue...

Porsche has a TSB out for certain Cayenne S's due to faulty oil scraper rings. Oil consumption on the order of a quart every 300 miles in these cars. I have the VIN numbers for the vehicles this applies to if anybody wants them.

 

Both his and mine are turbos for which there is no TSB.

 

But aren't they the same engine base, so it could be the same issue with no TSB yet. CT owners could just be more gullible and not have created such a stink yet. This is what happened on my Audi Avant a few years ago with the ignition coils, then when enough people complained and they had enough repairs in to document it, they created a TSB.

 

tt buyers aren't necessary more gullable but just buy elsewhere the next time instead of investing the time and energy to resolve something that should have been voluntarily (to say the least!) resolved (or even acknowledged) by now in such a high end SUV. this is not the sort of activity that generates the necessary motivation to become a repeat buyer of a product which carries up to a 100% premium over the rest of the products in the market.

 

Good point...

I hope you know I was joking about the gullable part. I was referring to the typical high-end vehicle dealer attitude of you have to "pay to play". I remember hearing this alot when my dad went in for service on his ferrari many moons ago and I remember hearing it the from a stereo dealer when I asked how much to reprogram my crestron. In the end many of us just accept it. It's the ones who don't who change the world

Cheers,
Corey
