I found this on Rennlist:

Hi all,

I received a letter today from my Porsche (UK) dealership stating the following.......

"Through regular quality inspections at Porsche AG, it has been identified that there is a possibility that the engine in your vehicle has been installed with the incorrectly machined crankcase. Due to a machining error, the intermediate shaft may not sit in the designed position in the crankcase. To determine whether this fault exists in your vehicle, the engine must be checked and depending on the result, it may be necessary to install an additional spacer to the intermediate shaft bearing cover."

I've booked the car in for the check (takes approximately 30 minutes) and will have to wait and see whether it's affected. Has anybody else on the forum received a similar warning?

Today I checked with service department at my dealer in Thousand Oaks, CA. Same story. Only a limited number of cars were possibly affected. My 997S was not one of them.
