Yeah Tom our cars are brothers I suppose!!! <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" /> The car was registered to its first owner in June of 1994... So I guess it was among the first 993's that hit the streets in USA...
Who said that 94's came with a lot of problems?
Mine knock on wood well on the 40K's is running very strong! The only thing I have seen is the more I look in the engine compartment the more 964 numbered parts I discover as well as parts made in 1993.
By the way yesterday my mechanic checked the car with the new diagnostic tool from Porsche and the ABS/ABD passed without faults of any kind.

Time for an update:
My car was at the dealer (Newport Auto Center): The brake fluid was flushed and the resevoir replaced because it was apparently full of deposits.
The fluid flush and resevoir change came close to making the pedal feel normal (still not quite firm), but the ABS pump is still a problem according to the diagnostics they ran (right front ABS sensor problem). They recommend replacing it along with the master cylinder.
Newport says the ABS pump is NOT one of the old style that is mentioned in the bulletin and according to Andial, so the control unit does NOT need to be replaced as well.
Anyway that would be ~$1800 for the pump and another $500 for the master cylinder (now that I think of it I'm fuzzy on why he said I need
a new one) and of course labor ~$500.
The deal is that Porsche would likely help out with the pump but only if I can come up with service records that show the brake fluid was
flushed at least twice (once every 3 years). I only have one of the previous owner's records in the car, which gives me the name of the dealer in Texas the car was purchased at and serviced for brake pads. The place I bought the car from (Tilos) told me they did a 60k service on the car to prep it for sale but I don't have their record on that either. Newport service manager said he would try to obtain the service records but I am not optimistic. Apparently the Newport mechanic said it looked like the fluid had never been replaced.
For now I will drive the car as is (not a safety issue as I understand it) and hope to find the missing service records.
Oh, also had an alignment ($325) and a new rear tire put on while it was in the shop. Sure nice to have it back.

Guys,
Here is some little facts about the 993 and the USA.
No 993s were imported into the USA with a 10th digit in the VIN being an R. All were S or model year 1995. However the build dates may show that they are, as already posted actually 1994 models. In fact they are 1994 models with a 1995 VIN. If you pop open your trunk lid, look on the underside of the lid near the front latch you will see a label. On the bottom line you will see the word "options". In this line should be option 718. This means that the VIN has been changed to the next model year. So you have a 1994 model year 993 which should have been updated to 1995 model status, will most likely have a 1994 model year engine and you will have S as your 10th digit in your VIN.
Confused, well Porsche did this a couple of times in other series as well. The 964 this was done twice. First with the RS Americas then with the 964s 1994 model run for the USA only.
I hope this clears things up,
Ciao,

PS: Model years are not calendar years. The model year runs from Aug 1st to July 31st (well most places, Porsche is an exception). If your 993 was built from Aug 1st 1993 to July 31st 1994 it is actually a 94 model. 993 production started in Jan 94 and the 1994 model year actually ended July 31st 1994. The 2300 993s from this production run that went to the USA went as Option M718 1995 models. In the 964 series model years started as early as May and major changes were made in the middle of a run as well. The USA version of the 964 1991 model year run started in May 1990 and major additional changes were introduced in July 1990 and in November 1990 and the run finished in July 1991. The first of the 1991 model year 964 and the last were actually quite different autos. None of this data is reflected on the data plates or delivery documentation either.
PSS: None of this applies to 993 owners with ROW versions. This only applies to US versions.
