IMS on a 99?
I've read somewhat conflicting reports on whether a 99 is or is not a good, 1% chance that is, candidate for the dreaded IMS failure. The readings I have made in favor of a 99 says that the design of the bearing, vs a 2000 to 2008(or was it 09?), insured that there was a very slim possibility of a failure. I think that I also read that the design change to the bearing was made sometime in the 99 manufacturing schedule. So if this is true then it seems that it would be a good idea to know how to tell if the 99 you were considering buying or owned had the older style bearing or the newer(bad) bearing. I would have to think this would be traceable by using the Vin# to look at Porsche's records.
Am I right in all this? Is there a published mfg date or set of Vin numbers or serial numbers that one could use as a guide?
