Faults:

Had DTCs for various air leaks, lean faults, timing on Bank 1 and over boost codes. Also the transmission would have faults after 20 minutes with PRND all lit up at once with very poor shift quality.

Parking sensors occasionally refuse to work.

Loud tapping on passenger side of engine at idle, was intermittent, now constant.

General Comments:

The fixes (so far) are cheap enough.

Air leaks, lean code and transmission fault fixed due to vacuum hose at the rear of the engine which was disconnected. Just reconnected and all was good.

Engine timing bank 1 code and tapping resolved with hydraulic valve lifter cleaner.

You'll spend plenty of time tinkering under the bonnet, where it's easy to break a heat hardened vacuum line.

Another air leak now (between MAF and throttle body again). I'm taking the car off the road so I can replace all the vacuum hoses, diverter valves etc.

Tyres are reasonably priced, but the front brakes are stupid expensive being the Turbo S, but I knew that going in.

Fuel economy over 2k miles is over 18 MPG.

Love the looks of the Turbo S when all kitted out with the Porsche body kit.

The drive is initially disappointing, but put the suspension low, and the shocks into Sport (assuming smooth roads) and press on and it's so very much better. Interior build quality is very good, but I have a corrosion on the leading edge of the body and one of the rear doors.

Great hobby car as long as the engine is sound, but you need a reliable daily driver.

I've decided to keep my one long term as it's not worth very much.

Faults:

Airbag fault.

Front tyre camber wear.

Faulty headlamps, poor connection in damp.

Gearbox selector problem.

Drivetrain vibration at 60mph.

General Comments:

Cayenne handles and performs well in V8 form, but seems plagued with lots of annoying faults that always require a visit to dealership, who seem to enjoy treating you like you're a pain in the ass. I have to say I've owned a few Porsches and the Cayenne seems to have had the most problems by a big margin.

Faults:

Head lamp failure.

Rear washer fluid leaks through head lining.

Engine leaking coolent through head.

General Comments:

Average handling, poor brakes and the worst build quality.

Cheaper running costs with a Ferrari!

First service cost £3800 brakes etc.

One month later in for airbag light staying on and yet more light problems. They ended up finding a coo-lent leek and couldn't find it - out came the engine and gear box, one month later after lending us a mini! I get my car back with a £4,000 bill... Porsche dealer told us Porsche would pay as good will as this had never happend before? Then told us they wouldn't... Got the car back and the final kick in the teeth - my CDs are missing from the changer - Bye bye Porsche!

Faults:

Non stop problems since owning the car, which has only been 2 months. The AC does not work properly in the front if the rear is on and vice versa, even cheap cars don't do this. The Battery/Generator comes on at least twice a week, it has been back 3 times for this, the last time, the car was scratched whilst in their care - they have put this right. The window wipers screech, and again the car has been back 3 times for this. Love the car, but am very disappointed in the faults. Altogether in 8 weeks of having it, it has been back to Porsche for 17 days, and needs to go back again!

General Comments:

Love the look of the car.

Handles very well, thinks it's a car.
