Reliability & Ability of 2007-2009 Cayenne V6, Your Thoughts?


oioioi

Recommended Posts

Hi, I’ve been looking at purchasing a Cayenne (V6) for some time. I’ve got my eye on three that fit within these parameters: 2007-2009 models with between 80-100,000 klms), most services (not all) done by Porsche.

I have searched this site and gained a fair bit of information, but I would appreciate your advice on 3 points if you would be so kind:

1. How reliable are these engines when they are 4-5 years old with this many miles, if they have been serviced relatively well?

2. Are there any inherent problems that I should look for with a used Cayenne (v6)

3. I have a 16 ft aluminium boat. The specs indicate a v6 should be able to cope with towing a boat of that size - anyone have any comment on that?

Any advice appreciated

Cheers

oioioi,

cant offer any answers here, but also interested in a Cayenne. I would like to know what they can tow, as I have a 3 horse float, so need to be able to accomodate about 3200kg. Interested in anybodies experiences....

cheers

To haul 3200kg i reckon you might want the torque of the V8 or the diesel.

I hear the diesel is just about the pick of the bunch for general duties - including towing as it has bags of torque.

Excluding outright performance from the V8 turbo of course.

My 2 cents worth is a good mate of mine has one and raves on about it so much he just bought a second one and states the new one is just mind blowingly fantastic.

Suggestion: ring a couple of indipendent work shops for a model trouble seeking guide.

Note: don't know how true this is however ensure your tow bar / electricals are installed by someone who knows the car as apparently the wiring on these models are very complex and many a tow fitter has totally shagged the electricals on a Caynne by accident through traditional methods which is a very costly repair. At least this was the reason the dealership gave him for an exceptionally expensive tow bar fitting.

Thanks for the advice so far - it's really appreciated.

I found out that the Cayenne V6 at Gold Coast Porsche (for sale on car point - $67,000 with 125 Klms) has a new engine as the previous one 'failed'. This is of course a bit of a concern...

Here is a email from the person i was talking about who i flicked this to - just incase it helps:

"Thanks for the plug on the forum Doish. The V6 is more than adequate for towing as we have towed the trailer and motorbikes from Sydney to Albury and it has done the journey about 8 times. It is so easy in fact you forget the trailer is behind the car. In hindsight, the tow bar does need to be fitted by Porsche or a Porsche recommended fitter as there is a single wire that services the whole car. The trailer electricals need to be spliced in to that wire as it operates all the warning lights. The V6 engine, according to both Porsche and Autohaus will run forever if well serviced. 2008 was first of the revised shape and I think, has the better looking front end of any of the models…"

I'd like the power of the V8 (I'd love a turbo) - but looking at fuel economy, so I prefer a V6. I know they aren;t as popular, but if it'll tow my boat that's all the power I need. ( I have some performance cars to go fast in, so no huner for speed) I think diesil would be good but I only want to spend 60-70K, so out of my price range.

Doish13 - thanks for the info.

This forum is very helpful to a Virgin-porscher like me.

Speaking about Cayennes in general:

They are fairly heavy on brakes. That's just physics: it's three tons of fun designed to stop like a hot hatch. Somethings got to give - in this case it's pads and discs. (Newsflash: Heavy, fast vehicle in heavy on brakes shocker!)

They also use up cardan shafts. There is a rubber flex disc which gives up, that can be replaced. There is also a central support bearing that can't easily be replaced, but your friendly independent Porsche specialist can supply an OEM cardan shaft for less than going to a Porsche dealer. Just like they can do for other parts on other models.

There is an aftermarket two-part replacement for the support bearing out there, but I have no first hand knowledge on how good it is or isn't.

In common with many cars from many manufacturers, the plastic coolant reservoir is something of a consumable. Again, not an especially expensive part.

Although the OP asked about the V6, the next point applies to early V8 models: The early V8 cars had plastic coolant pipes which were later replaced with alloy. It's a popular, straightforward and worthwhile coolant system upgrade to V8 cars to install a "valley coolant hose kit" if/when the plastic pipes leak.

Finally, the cars are now reaching an age where I get regular requests for starter motors.

Lest this read like one of those bits of internet "wisdom" that look scary, these are all really just reflection of physics and the age of the vehicles.

Without answering your question directly...many modern engines are more economical in $ terms when running higher octane fuel because they are able to advance ignition timing further.

Cheaper fuel doesn't necessarily save you money.

I'd go along with whatever it says inside the fuel filler door...or higher octane.

By the way, how critical is it to use premium unleaded? Do these engines really need a higher octaine level - the compression doesn't seem that high?

Don't take this as a dig as it's not meant to be but if you don't want to fork out the extra money for good fuel then you may want to reconsider getting one. It's a Porsche and even in this great day and age of getting parts from OS to service a car its still not going to be "Cheap" to maintain. The cheapest item on the service list of any car is good fuel..

Some more reading on used (high mileage) Cayennes.

Two warnings:

1. It's a bunch of whingeing Poms

2. When you see what Poms pay for cars, you'll wonder why they whinge. (Hint: Look at the colour of the sky outside today.)

No worries, not taken as a dig. I run premium fuels in my performance cars (GT40 & 360 Ferrari), but it seems most cars these days recommend that premium is used (even my daughter's Yaris!) so I wanted to find out from those with more Porsche expiriece, whether there is a genuime reason. I dont; mind spending money - but not unneccessarily. Thanks for the advice - I'll be buying premium based on this feedback.

I can kick in a little experience of Cayennes, having spent a reasonable amount of time behind the wheel of each variant....

- Every day performance difference between V6 & V8 on road is negligible.

- Turbo Cayenne is wicked at Autobahn speeds

- I would buy a DIESEL Cayenne EVERY SINGLE TIME.

why ?

The day to day performance 0-60, or 70, or 80kph is sublime. :):):)

Effortless fluid torque....... giving you usable power where and when you want it.

Perfect for towing for instance ;)

V8's are renowned for munching coil packs .....@ $600 each. .....do the maths.

I am not sure if the V6's do this as often. James ??

Obviously not an issue in the diesel.

Also be mindful of all the cabin electronic auxiliaries - heating / ventilation. $$$ when they dont work correctly.

I haven't seen much of the V6's at Autohaus Hamilton, so can't comment on whether the V6 eats coils as frequently as the V8's do.

$600 a coil pack? That sounds like a dealer price...it would be a LOT cheaper at an independent.

Q, I missed your post earlier.

I try and flag up in as many words when I am plugging Autohaus Hamilton, as opposed to just providing opinion.

In this case it was a comment on independents in general vs Porsche branded workshop pricing. Your original post re: $600 coil packs just depressed me 'cause I can only dream of charging that much for a coil pack. B)

And lest I be accused of bashing, there are reasons why one may prefer to take a vehicle to Porsche workshop. As with any automotive brand, the independents will always be less expensive.
