    Are any of you still running first generation exhaust variators? I just purchased a one owner '99 with 4K miles that has the original variators. The car shows in the Ferrari system as having the variator campaign completed, but we have confirmed this is a mistake. I am working with a very helpful service manager at our local dealer to correct the car's status in the Ferrari system so that we can hopefully get the work done and have Ferrari cover the car under the campaign.

    My concern is over how long I should wait before getting the work done while we sort through the issues with the Ferrari system and incorrect campaign status. The belt service was done two weeks ago at a different local dealership.

    I have read all of the variator failure/concern posts and while there seem to be a few failures of the early design on tracked cars I have not seen much for street cars. I have also seen the posts on the updated variator design failures.

    Thanks!

    Even if you get it corrected in the system Ferrari only covers it during a belt change so changing them 2 weeks ago wasn't necessarily a good move.

    Having said that, my car had over 20K on gen 1 variators and a number of track days with no incident. I had them changed recently. Ultimately this comes down to your risk tolerance. The variators can fail and they don't give notice so how much risk do you want to take?

    My soapbox rant: You guys want these low milage cars with one owner.. here you go: the one owner never had the campaigns done and the system sounds like it was erroneously recorded as entered.

    My response: Variator failure is relatively rare. The reason they fail is the stem where it connects to the exhaust cam on the variator is long. This stresses the metal and cracking occurs. The updated variators are 190042. I presume the part numbers on the variator are what was used for comparison? The risk is small but real, there is no way to tell if/when they will fail. You will make the determination whether to drive or not. BTW the repair manual states that the variator has a lifespan of 100,000 KM! Most failures, including the 3 bolt starter ring seem to be greater on tracked cars than street machines.

    My car had absolutely no records at all. No manual, no conversation with the prior owner. None.
    I was able to determine based on belt serial numbers that the belts were changed in fall of 07'. Thus this fall they get changed out. I don't know personally if the campaign was done (mine is a euro).. but seeing how the fuel sender does read completely full, the OBD2 port mod has been done (has it on yours?.. just some wiring to the OBD2 port).. I wouldn't be surprised if the variators in my car have been done in the past. This is the one advantage of multiple owners. Someone will have asked that question in the past and they stand a higher chance of being updated.

    Thanks guys. Appreciate and understand the soapbox rant (LOL), but I was not looking for a low mileage car nor was I looking for a Ferrari as this is my first one - this car happened to become available and given the condition, color combo and options I decided to go for it. '99 F1 coupe, grigio titanio, blue interior, all leather interior options including matching steering wheel, carbon racing buckets, spare tire and integrated battery charger.

    The car has had the starter ring gear and instrument panel campaign done (I have the service reciepts) and has not had the variator or OBD port campaigns done.

    I wish I (and the dealer that did the belts) had caught the variator issue when the belts were done a couple of weeks ago...

    On all of this we do agree. And yes I know that we don't always agree and I probably rub you the wrong way sometimes; but, I do respect your contributions and abilities.

    Anyway, as you know the campaigns are not tracked on euros so you can only depend on what you see and what you have service records for, not FNA records. I had my variators checked during the last belt change, then I had them replaced. It really isn't that bad. We had to take the cams out and machine them off but think of it as an opportunity to degree the cams and fix that leaking valve cover gasket :)

    I have 102km so I would imagine mine have been changed ...I will do a belt services this winter ( even though Karl said I had a few more miles to go) and will have the checked

    Skidkid not at all! :) These forums are best when people disagree on things... it gets us talking and some spicy debate is a good thing in life! Thank you for acknowledging whatever I can offer to the forum. :)
