955 longevity?

Hello all,

I have owned my 2005 955 for the last 10 years. I’ve mainted the car regularly by changing all the fluids frequently and had the known issues with this model repaired. My current mechanic and past have been independent specialists. It now has ~140k miles on it and it’s now my wife’s daily which she puts 8k a year on it. I know the car is not worth much compared to it’s original price and therefore we won’t see much in a trade in. My question for all of you is at what point should I get rid of this car before it costs too much to maintain? I am looking to know when major failures typically start to happen and the repair cost/car value doesn’t make sense anymore.

Thanks, Leo

Leo,

At this point - as you realized the vehicle isn't worth much anyway.. high miles, 12+ year old German luxury cars don't go for any real money. You're probably best off driving it until something that costs more than 1/2 the value of it breaks and at that point, donate it to a charity and get something new. Or sell it for a few thousand bucks as a mechanic's special or a parts car.

Leo,

I second Don's comments. It's California car if nothing has rusted out, unless your living in a beach community.
I would suspect that it has not been driven hard to cause premature drive train failure,no car payment is perhaps a plus.

I'm in the same boat several cars several cars over 10 years old but with low miles, with no value.
My motto is drive it till the wheels fall off.

I am expecting 500,000 miles and I just crossed 230K last week. She's running stronger but a bear to keep up. So much in fact I call mine Hitler's Revenge and what a sweet revenge at almost $3 a mile to run.

Buy a low-miles Co-Part salvage and store it in a dry place. There, you just prepaid parts cost to go to 400k....

You guys with these high miles, have you ever had the turbos replaced?
i am looking at a 2005 with 146k and am wondering how long the turbos might potential last before having to drop the engine for replacement.

Thanks

I’ve been reading the Cayenne forums for about a decade now and have yet to see a post about a turbo failure.

Agreed, I have read that Turbos are made by Mitsubishi and could be rebuilt if needed by a company like Turbolab. I saw a post or DIY, guy removed the Turbo in vehicle took a week but save the dreaded engine drop.
I have almost 170K on my 985TT. Just replaced the diverted vales as PM.

+1

I've read about 1 cracked housing, yes exactly 1. Some turbos were replaced incorrectly before the crankcase ventilation system was understood and oil showing up in the driver's side intercooler was mistaken for blow-by and a failed turbo, when it was really condensed oil vapor being put back through that side for emissions purposes.

Yes. It was posted on another group by a Porsche service adviser that snapped the picture while it was in for an oil change.
