Hey guys. This last weekend I drove to and from Portland, and noticed something I hadn't seen before with my (relatively) shorter trips.
The first thing I noticed is that my odometer trip reading was far off from what I was expecting. My Google Maps trip length was 167 miles, but my odometer only read 149, with 10 or so miles on there from before. I also compared the trip odometer readings to mile markers though I'm not sure those can really be trusted for any degree of accuracy; my trip reading was generally 85 to 90% of a mile between each marker. Using a GPS based speed app on my phone, my speedometer is reading within a couple percent of my 'actual' speed. My tires and rims are stock sized.
I'm wondering where the inaccuracy is coming from. How accurate are the odometers in these cars generally? Is it possible my 1.8T gauge cluster is screwing with this somehow? (That gosh darn previous owner... )
I wouldn't be all that worried about this except that I want to be good with scheduled maintenance. If I'm going to be replacing my timing belt a little before the next 100,000 miles, then based on the odometer reading there might actually be more like 115,000 miles on my belt... It's also of course nice to see how my FE is doing.
