coolant pipe rupture 4.5S

[tiskev]

Is it inevitable that my engine coolant pipes will rupture ?
If and when they do will I get home with it or have to call ot the AA or someone ?

 

[Mike_Pollock]

All pipes will go eventually! - (wasn't aware of any particular problems for Cayennes)

If they go, it would usually be a flatbed to a garage.

Thanks Mike ,
I get the impression that most of them have been replaced.
It certainly seems fairly common

Pipes going is one of the few known faults.

No coolent means pull over asap and call the tow truck Im afraid.

If they are going to burst i am wondering if i should
pre empt it and have it done before it happens as I do
motorway runs in France and would hate to get stuck
somewhere .If it is a known fault would Porsche replace them for free ?
The car has done 40k miles but it is an o3 (owned from new )

When I was looking for a Cayenne some time ago I was informed by the OPC Technicians that plastic pipes are a real problem as they get brittle with engine heat.

Thanks Peter
Anyone know of a modification to the composition of the pipes .
Is there a particular mileage one should be aware of ?

Hi Kevin

I think the best bet would be to as the OPC or an independant.

I recall from memory that they may well be replaced with metal pipes as a mod.

 

[tiskev]

Thanks will ask Tonbridge .If metal is available i will go for it and have it done
probably in France as labour is only around £50 ph . which would reduce the cost
considerably.

I can categorically state that it costs 2K Euro for a French dealer to replace the pipes.
I've seen the invoice

 

[tiskev]

Thanks David .I am really surprised that it is more .Perhaps it was Antibes ?
I get all my Mercedes serviced in France but have never had the Kn done there or the Boxsters .
I had a quote today from OPC of £1200 give or take £100 for the job .Apparently you can have the option
of metal or plastic pipes .Porsche declined to contribute to the cost .Malheureusement [:-]

My coolant pipes failed suddenly and dramatically without warning,under full throttle up a hill,I thought there was a fire and actually called the fire brigade,it was fixed under extended warranty and the replacements are updated and are metal.
I was upset at the time,ask your dealer for a deal on the labour and parts if it is a preventative fix.
My Cayenne is an 06 MY S ,above 90k at the time.Been perfect ever since.

 

[majorporsche]

Surely then the fact that Porsche will not contribute means that they do not see it as a real problem. I have extended warranty and wonder if it happened to me it would cost them a lot more in the long run. So why wont thwy do it before the pipes go ?

 

[tiskev]

Thanks Mark .Maybe i am jumping the gun too much if you got
to 90K miles before it happened.However mine is an 03 so perhaps
that should be taken into consideration ? Although I have had it
from new i have never extended the warranty so i suppose that is a
saving of several thousand pounds .A second OPC has offered to knock
off the club discount from the work and has said they are now all metal .

 

[tiskev]

Well Major I guess if they just accepted there was a problem
it might open the flood gates so I guess they do see it as a real problem.
I wonder when the actual modification came in obviously after 2006 .
Roughly speaking it is £500 for the spares and £500 for the labour
on that basis about a 4/5 hour job .
DARE I DO IT MYSELF ? .................

New pipes look like these;

We have the kit in stock, worth taking with you if your going on a long journey!

Can be done DIY if your good with the spanners, allow a days work though

 

[tiskev]

So that is what it is all about
Many Thanks

I have had them done by my OPC.
They are quite solid plastic pipes OPC said they were actually OK
I dont know if they had gone hard with use or whether they are hard
plastic to start with.Anyway it gives peace of mind having them done .

Now of course the drive shafts have started to rattle again
