Cayenne Coolant Pipes / Hose - Warning

[hadenough!]

I recently bought a Cayenne, as part of my due diligence I ensured I had a reciept for the coolant pipe replacement works.

At the weekend it left me stranded having dropped its coolant at the side of the road, fortunately the warning flashed up and I pulled over and switched off the engine before the temperature started to rise.

Turns out theres a coolant hose (not pipe) part No 955 106 323 50 which has split. This would have been done at the same time as the rest but wasn't.

The result, a £600 bill to replace a £30 part...which is likely to need replacing again in another 50000 miles to be on the safe side (The cars an 04 reg with 75,000 miles).

Sorry to hear this, are you saying that the plastic pipe was replaced but not a hose? If the hose that has failed was also fitted along with the water pipes (alu) then would it not be covered by the 2 year warranty on porsche genuine parts?

Might be worth a quick call to the garage if it was an OPC that carried out the work.

Good luck.

The hose wasn't replaced. It would have made sense to as its a known weak point and would have been accessible.

The pipes were done at Tonbridge along with other works totaling over £3k in july 2011.

I've emailed porsche giving them the background and suggesting the replace the hose when replacing pipes in future.

We'll see if I hear back.

you can't win with stuff like this, you done the right thing in checking that the coolant pipes had been changed and then get hit with this, just bad luck. Interesting thought now arises, is it better to get a car without the pipes having been changed, but obviously reflected in the price and then personally over see the job, with the standard "whilst your replacing them is there any other items that should be addressed" quote at the service desk.;)

Might be worth getting the plastic T piece (specific to the turbo) looked at also at the back of the engine as there seems to be some talk on rennlist about these starting to fail.


Good luck, and I'm still on the hunt for a car...

It's the plastic t piece that went...

Hi the hose you found had split is a seperate issue to the plastic pipe failures,rubber pipes can fail at anytime even if they look ok.I have fitted 5 coolant modified pipe kits in the last 12 months without any further issues.

I understand its separate but given it gets brittle with age it would make sense to replace it while your in there anyway for the sake of a £30 part given the labour involved with getting to it.


Wouldn't it?

OPC Silverstone replaced same said plastic T piece when I asked them to preventatively resolve the coolant pipe issue on my 03 Turbo without asking for it specifically. Bill came to £1200 from memory.

[hadenough!]

OPEC tonbridge charged similar but didn't bother.

The part numbers 955 106 323 50 if anyone interested.

We had two of them fail around 6-9 months after we replaced the lines to aluminium pipework. After that we offer to change them when we are in there for around £150 extra. At the end of the day it is not a usual pipe that splits or cracks.

It is a mouled pipe with a plastic T piece and this fractures.

There are a lot of pipes that you "could" replace whilst there but where do you stop ?

As it happens after changing this T piece pipe it seems to be the end of this problem.

Thanks mike, that sounds positive. Go on, upset me, how much would you charge to replace it as a stand alone job?

Around £450

To be fair, the dealers haven't stung me to badly considering then. Thanks.

I've seen a lot of serious debate on here on this topic, and to be fair I don't know how concerned I should br. I bought a January 06 plate Cayenne S in April from a Land Rover dealer and in the seven months I've had it, apart from a few trim and stereo things to sort, it has been absolutely perfect in every way, apart from the lack of air suspension over speed humps.....

I paid 14.5k for a six year old car with a perfect OPC fsh (Solihull) and 45k on the clock, now 49k, should I be worried, or should I chance it? I read the OP's thread when he was buying his Turbo, good read, thank you, but does anyone have a "feel" for how likely this problem is, and is a fairly hefty preventative bill worth paying for to avoid the downside? I'm not enquiring about achieving perfection, just a balanced view on risk versus hole in pocket?

I would be grateful for a steer from those "in the know".

Personally I'd get it done, the hose in question here is specific to the turbo so won't be an issue for you though. If the main coolant pipes go in a big way, they can release coolant in to the bell housing which may result in future gearbox issues (someone please jump in if I'm talking st).

For the sake of peace of mind now and future resale I'd suggest doing it.

It would yes but where do you stop?

You could replace a whole load of other bits and bobs "just in case" while you have it in bits.

Pain in the arse I agree

I was I have to say rather ignorant of this potential problem when I bought my 04 4.5S in November 2010 62K miles. I found out about it when the coolant pipes went at about 75K and happened as I was pressing on somewhat on a nice stretch of A road near Great Missenden and braked heavily for a roundabout . The horrible warning tone (you think oh what now - I had had several bulb problems before this with the cornering lights) followed by "check Coolant level" I was able to limp back to the office and then home where I topped up keeping a wary eye on the temp guage. It didn't leave me stranded is what I'm saying. More topping up and ended up taking it to a local BMW specialist who had been brilliant with my previous car (Tim at TCS - top man). He confirmed that the coolant pipes had gone and there was a kit from Porsche about £500 I think but the final bill was nearer £1,200 as a lot of stripping down to get to them.

Touch wood no problems since then now on 83K and goes like a (1st class) train I love it.

This is the conclusion I'm coming to, just one of those things I guess...the pipes were changed almost 18 months ago an I'm not sure this t section hose was a known issue then.

[hadenough!]

So, cars back and I'm £510 lighter, but porsche reading have been excellent, mad parting with my hard earned (almost) a pleasure.

Great news. Is the car pretty much 100% now?
