I am getting ready to take my first road trip in the box. This will be through the Mojave desert where authorized Porsche service centers will be non existent. Bubba's service station is about as good as it gets! My car is a 98 w/92k on the clock. Since it had the original water pump that I recently changed out and with no indication the AOS has been changed in 18 years, I ordered a new Genuine Porsche unit from Pelican to replace this week. However reading Ben006 thread with JFPinPA and Jake Raby stating new units failing all the time, I am reconsidering. Sometimes TMI is TMI. I am certainly not afraid of the work but I do not want to change working fine old for possibly failing new. I also know the "if working fine why mess with it" theory. I would like to change but now not sure. This is a Genuine Porsche AOS, any suggestions to reduce my anxiety???

Thanks
