I have a 2000 Passat with 53,000 miles. The service manual says to replace the timing belt and tensioning roller every 105,000 miles except for CA, VT, and MA. For those states, it says to replace at 60,000 miles. Why the difference? What's special about those states? Is it emissions?
Ha! Never noticed that before...I'm curious about this difference too. Your statement about emissions gets me thinking of how a belt could affect emissions. If a rubber-fabric belt can stretch with use, and/or teeth on a belt can chamfer or wear thin, then timing will be slightly altered by the worn belt features.
Personally, I would change my timing belts (on any car that has them) between 60-70K miles. If you are going to stretch it to 105K, make sure the specified belt inspection is performed according to the maintenance schedule. You can inspect the belt yourself, all you can really do is remove the covers and look for damage and/or fluid contamination (oil, mostly) anyway.
That's all the dealer techs can see...obviously a properly documented check would be best.
Might be refering specifically to TDI's as well...not sure.
Standing in the shadows with a huge hammer, waiting for all your dreams and hopes to materialize into bunnies!
Josh is right on regarding the interval...every 60K is the interval. I have seen a couple of examples of cars that didn't make it to 105K before the belt broke..VW covers those cars under warranty (Powertrain, which is 10/100,000 for the original owner and 5/50,000 for subsequent owners) up till the expiration of the warranty, after that its on you. However, all newer models have the 60,000 mile replacement interval, and TDI timing belts are to be replaced every 40,000.
OK, I'll change it at 60K. I just don't get why California, Vermont, and Massachusetts are singled out in the service manual. What? The belts don't last as long in those states? Maybe the lawsuits are costlier for VW in those states. Who knows?
