Quick Question

Is there any easy way to check the Porsche dealer service history of a 964?

I have the history of my 91C4 which has a bunch of paper history which seems to indicate that there was a warranty replacemnt of a faulty flywheel back in 1996 at 28,000 miles. The part number from the sticker and scrawl on the back of a work order is 964-114-012-02 which, fingers crossed, seems to indicate that a LUK was fitted......but I'd love to make sure....

Also I finally braved up to check whether my 964 had one of the early problematic engines - now here I was not hopeful as my car has a build date of 1-7-91 according to the drivers door label but,
and please no-one tell me I'm wrong here cos that would ruin my day, my engine number is 62MO7566
which puts my engine some 700 units after the changeover (which I've read came after engine 62M06836).... I guess I was surprised (but relieved)that a car built so early in 91 should be so deep into the second gen engines????

Great Web site - keep it up

 

Hello Ruairidh,

Trace the owners of the car before you, ask them where the car was serviced, and go or mail to the dealers for a follow up history.

And on the Engine thing, ask Adrian + Roland Kunz from Rennlist, because they are the specialists!

High,
According to the numbers you should have the engine update, actually 1/91 isnt that early in the production run, i think it actually started in 9/90, my production date 11/12/90 w/ engine 5798 unfortunatly didnt make the cutoff, BUT has NOT leaked a drop of oil in the 12 years i've owned it....you should be good. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

 

ruairidh:

You have a LUK dual mass flywheel in your car and the engine has the factory updates! I checked the part number for the LUK part with AllData.

Dear Ruairidh,
I will only deal with the first part of your question. Bill has provided answers for your second question.
Verifying the maintenance history of any auto but in the this case a 964 C4 is not easy. There is no requirement for repair facilities to keep records and histories. My personal experience with this is massive memory loss. Mind you to be fair. Why should a facility in 1992 keep any particular auto in mind.
In the USA you have the Cardex system which will provide the initial data from delivery into the USA.
7th January 1991 is quite deep into the model production year. Those engines may have been sitting around for a few months already. It is quite complicated to explain but quite possible for somebody with an early build 1991 model to have a very late engine serial number. A common cause of this is initial engine installed, fails and has to be replaced,
Ciao,
Adrian

PS: To confirm a LUK is installed takes a little effort but can be done. You have to lift the C4 up. Remove the engine cover, slide in underneath, locate the starter motor. You should be able to see the fylwheel starter ring. This is welded on a LUK and quite visible. I do not think you need to bother because the paperwork confirms a LUK.

 

hallo
Hre in Europe we read the Date backward !
So 1.7. 91 is 1 July 1991,not 7.January 1991 .
So your car is a very late 1991 Modell.
