One of those $249 notebooks perhaps?Hate dual boot partition and/or virtual machines. I'd rather buy a windows portable and chuck it.....

I have no issues whatsoever running W7 under boot camp; you don't even know its there until you use it.

MSRP on the mirror motor assembly is only $100.

Parts are obviously cheaper over there unlike cars.

Not available locally, had to be shipped from Germany actual price $163.

My Porsche Indie did this for me parts for one side about $170 + 2 hours labour.

Stripped gear on the drive caused by someone manually putting the mirrors back into place. The gears become brittle with age.

I'm not sure of the wording in the UK warranty but this is an extract from the PCNA warranty:

Note: Your vehicle is a mechanical device. All mechanical devices make some sort of noise and/or vibration, and these

noises and vibrations can differ from vehicle to vehicle. Porsche Cars N.A. recognizes those noises as normal and characteristic

of the product. Normal noises or vibrations as determined by Porsche Cars N.A. can be anything from brake squeal to road

vibration. Therefore, normal noise and/or vibration and/or deterioration as determined by Porsche Cars N.A. or its representative

are not covered by our new car Limited Warranty.

No PDCC or Sport button beside the PASM controls until 2008 but they are still a fun drive. The number of people who by a $100k luxury SUV with serious offroading in mind is limited hence vehicles fitted with the offroad package (including rear difflock) are rare. Offroad traction is achieved by use off a lockable centre diff and automatic differential braking (of wheels) front and rear.

If you're getting vibration in the armrest area it might well be the cardan shaft.

The DENSO part No for your car is DPC28010

If I google 60-01801 NC I am taken to the web page of discountacparts.com for Panamera 4.8L 2010-2012 which has a DENSO part number DPC28014 which clearly a different DENSO part number from the one which you require.

If now look up Porsche Cayenne 4.5 liter on the same site I again come to their ID no. 60-01801 NC. Click on the thumbnail to obtain a larger view and you get a reasonably detailed view of the compressor with this written underneath it

This is an exact* picture of your part. We do not use generic pictures. Our cataloging team is the best in the industry and it ensures that you get the right part, the first time.

If I zoom in on the label on the compressor there is a Mercedes logo and what appears to be a Mercedes Part No 000 230 62 11 (closest I can find to an actual part number) which again has a different DENSO part number DPC17111

All are 7SEU17C compressors but they are not identical

So, do both compressors look the same; have the same model and version numbers? Pictures?

Mine only affected me at low RPM until it wouldn't rev at all.

Have you had any fuel pump problems yet?

955-522-080-03-9B9 Support (in satin black) -- US MSRP $5.38 each

Difference between 04 and 06? Looks the same on my 05 and 09s :huh:

There have been three different part numbers for these - so maybe the newest ones do not break.

That would be nice! Thanks :thumbup:

I have a broken one of these in sand beige, so a useful exercise for me too! I think this should be it.

The unit is clutched but not magnetic clutched. If there is a single electrical connection on the body (see below) which ultimately leads to the rear of the unit, this provides the control signal for the solenoid operated proportional valve which angles the swash plate. Please note in the illustrations in my previous post there are entries for clutch type but no entries under voltage which indicates that the clutch is not electrically operated.

If you have a wire going to the front of the compressor connecting to a unit like the second illustration, you have a magnetic clutch.

According to the DENSO catalogue, (I found the latest one) all 955 Cayennes are DENSO SE type compressors 7SEU17C in the V8s and 7SEU16C on the Cayenne V6s.

A good explanation of the various compressor types and the clutch operation on direct drive units can be found here

McBit500 post shows it should not be clutched.

My illustration is taken directly from the Denso Catalogue, which interestingly does not list an application for the V6 Cayennes.

If the unit does not have a magnetic clutch it will have a torque limiting slip or fail device, normally termed a clutch. This is designed, dependent on type, to slip or fail in the event of system overload or compressor failure and should reduce the likelihood of serpentine belt failure, yours may already have done so!

I would find it a little odd if both magnetic clutched and direct drive compressors were fitted to identical AC units on the same vehicles as the direct drive compressor requires an infinitely variable supply voltage to provide proportional control of the swash plate and the 'Mag' clutch version requires only a switched 0v/ 12v supply. Just my thoughts, I have no evidence to the contrary

The cross referenced type designation for the AC compressor on all 955 V8 engines is Nippon Denso 7SEU17C this unit has no magnetic clutch and is continuously driven.

cool. so the 'there is different compressor for 4.5 non turbo and another for 4.5turbo' is kind of bs.

I have this info from few sources now, 2 compressor types, one for 3.2 and another for 4.5 (all flavors). Thanks.

Please read the post again; there is one part number for all 955 V8 engines.

According to Sonnen's website, the part 94812601101 has been superseded to part # 95812601400

My understanding is that this a Porsche updated part number for the same item.

According to my copy of PET there were 4 different part numbers for the A/C compressor on the 955 V6 and one part number for all of the 955 V8 engines. However for MY2005 your dealer is correct there is one unit for the V6 (955 126 011 01) and another for the V8 (948 126 011 01)

The standard boost pressures for the 955 CTT and CTTS are well documented: 1.6 bar and 1.9 bar respectively. Does any one know what the equivalent boost pressures are for the 957 CTT and CTTS are?

There are a few threads on similar issues on Rennlist which all seem to be pump related. How is the Inland Sea these days?

Glad to hear that your problem is solved. Batteries are funny things, I just bought a 2009 CTT which had a dead battery when I went to look at it; I had it PPI'd and the shop confirmed that the battery was shot. The car did not have service book with it so I obtained the FSH from the local Porsche dealer (at which point i discovered that this car had actually been owned by them since new) and found that the CTT had a new battery about 18 months earlier. Since putting the latest new battery in I have issues at all with the car. However, I have a 05 CTT which is still running well on the original battery 8 years later.

As a side note, receiving the FSH of a dealer owned vehicle was a real eye opener as all the prices, parts and labour, on the service sheets are COST not retail. One example being Mobil 1 at 60c/ltr as opposed to the $1.25/ltr that they charge the public.

Since the occurrence of your problems seems restricted to starting or low speed running I would suspect a low voltage issue: bad earth/ battery/ alternator.

I believe 2006 CTT and CTTS are capable of a maximum boost pressures of 1.6 bar and 1.9 bar respectively with the gauge reading only the portion above atmospheric pressure.
