The tires were changed out 2 years ago along with the fuel pump, O2 harness and O2 sensor.

Then strip, clean, rebuild and repaint the calipers.

But, it is basically impossible to inspect those components even with a PPI.

Regarding the brake flush - what would you recommend doing to get all the gunk at from the piston bores?

Additionally, since he performed the oil change about 2 years ago, I'm assuming sampling and testing that oil would not be an accurate read on the engine's internal state (corrosion, damage to the cylinder walls, etc.), right?

U may want to post in the turbo section but the tt does not suffer from bore score and does not have a imsb so lack of oil changes may not be as big of a factor.

16 years is quite some time for oil to be in an engine that has probably idled and putted around town for most of those 16 years.( hopefully it wasn�t run too hard with that oil) Keep in mind that the coolant has a lifespan as well
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello Rennlist
Long time lurker, Porsche dreamer, but hopefully soon to be 996TT owner! I found a low mileage X50 example with approximately 12k miles belonging to the original owner. I'm scheduled to check it out in person sometime over the next week. Everything seems to be fine with the vehicle except for its lacking maintenance history. After some dialogue with the seller, I've come to find out that his first engine oil service was in 2019 - THAT'S RIGHT, 16 years!!! He was under the impression that the first service needed was at 15,000 miles and was not aware of the 2 year interval for engine oil and brake fluid services. I made him aware of this huge concern and he has agreed to perform the brake fluid flush before we meet. I'm hoping there's no corrosion to the brake system components, such as the lines, master cylinder, calipers, etc. But, it is basically impossible to inspect those components even with a PPI.
Now, my second and main concern: the engine oil. Should I be worried? Or better yet, walk away?? I REALLY don't want to, but I am trying to make a logical, sensible decision. What can I (or specialist shop) do to address this red flag? I don't think dropping the engine and taking a look inside is an option. Additionally, since he performed the oil change about 2 years ago, I'm assuming sampling and testing that oil would not be an accurate read on the engine's internal state (corrosion, damage to the cylinder walls, etc.), right?
Thanks in advance for your feedback!
U may want to post in the turbo section but the tt does not suffer from bore score and does not have a imsb so lack of oil changes may not be as big of a factor.
You should be very worried, this could drain your bank account from repairs in days, possibly even hours! I will gladly buy this to save you any headache, just forward the contact information and you can thank me later.
Is the engine sump pan as easy to drop as a regular 996? If so, it can be removed in a few minutes. That would indicate any sludge or build up that would be concerning. You could always replace in situ then have it towed to a shop to be resealed after all the fluids are replaced.
Yes that would be a great concern if you are going to pay a premium for it. It probably will be fine, but the whole purpose of buying a low mileage car is to avoid maintenance that comes with mileage. At 18 years old it is going to require quite a bit of maintenance if you plan on driving it at its potential limit or close to.
add coil packs. and battery and fuel filter.
how was the vehicle stored? humidity? temperature?
depending the rubber hoses throughout the car could need replacing.
Brake rubber hoses, tires? Coolant flush, motor mounts. Pretty much everything that is rubber is suspect. Not greatly important if you are going to putt around town, but keep in mind the car is capable of 200mph (not that you�re probably going to do that).
if the price is reasonable and you aren�t being surcharged for excessive low mileage I say go for it. Sounds like the car was / is a bit of a museum piece that wasn�t regularly run. It�s probably one of a handful that have that low of mileage.
And BTW, flushing the brake system out m, doesn�t necessarily mean you get the crap out. Remember the bleeder and the inlet hose of the calipers are on the top and all the crud goes to the bottom of the piston bore.
Seller stated it was garaged stored in California weather. I did a google search on his address and saw the car on his driveway.....
I'm debating asking him to cover the cost of either a compression test or parts (coils and spark plugs) during the PPI.... I'd rather know the status of the engine and lose out on one of those costs (compression/leak down or parts). But, still mulling it over.
What would you suggest to do then? The flush was going to be done at the PPI shop.
16 year old oil that has been started 1000 times and doesn�t get to operating temperature often will get water and also gets acidic from the fuel wash. Usually this is harder on the bearings than piston rings and compression. It�s probably fine, but I wouldn�t call it well maintained with that service history regardless of the low mileage. 16 years is quite some time for oil to be in an engine that has probably idled and putted around town for most of those 16 years.( hopefully it wasn�t run too hard with that oil) Keep in mind that the coolant has a lifespan as well
Its definitely about the price, because a well maintained fluid changed 12,000 mile car would be more valuable than the one that has been purchased and just driven.
How old are the tires on this car?
That�s a long time! But how long is a lifetime? Craftsman tools were lifetime.and still are, but you will spend half your lifetime trying to get the correct replacement.
The tires were changed out 2 years ago along with the fuel pump, O2 harness and O2 sensor. The oil and filter were changed out at this time as well. Regarding the brake flush - what would you recommend doing to get all the gunk at from the piston bores?
Really couldn�t tell you but disassembly. I�m sure there�s lots of cars running with older brake fluid than that. I think you are going to get a flush and maybe all will be well.
1) Don't panic.
2) If you like the car, and it drives well, buy it. Expect to need to do catch up maintenance and random things to quit working. It is, after all, a 20 year old German car.
3) This advice is worth what you paid for it.
4) If you can really buy it for $60k, buy it immediately sight unseen and flip it on BAT for 90k+.
I wouldn't worry too much about "gunk" in the brake fluid.
The flush is mainly to get any moisture out and replace it with pure brake fluid.
Also it is to help prevent corrosion.
I see cars all the time that are as old or older with even more miles on them that have never had the brake fluid flushed.
Most have no issues.
I would never do that with MY cars, but I do see it constantly with client cars.
If for some reason you believe there is gunk, remove the calipers and flush the lines.
Replace any rubber lines and possibly master cylinders.
Then strip, clean, rebuild and repaint the calipers.
