when i first got my tC my mph was on the dot. now its like 2 mph off...it only has about 3k miles on it so i cant be the tire wear right? is the counter thing dirty?

 

how can u tell its not accurate? what counter thing?

 

uhh.. what?

what are you comparing it against?

 

the side of the road speed radar. theres a few around where i live. when it my car has barely 100miles it showed the same speed as the radar.

now its about 2 miles off.

also my sisters beetle does this too but its more like 4mph higher.

 

I think he means the speedometer, not the odometer, you might want to change your title....

 

the "side of the road" radar is crude equipment... 2 mph off is like nothing on an analog meter..

if you're that crazy about it, get yourself a GPS and use that instead to compare.. not some run-of-the-mill radar thing on the side of the road.

 

psh. i dont think its that big of a deal. i have gps, and it is roughly 2-3 mph off the my cars spedo, and my dads truck's spedo.

 

yah my gps is off by 2-3 too. you cant get everything dead nuts. ive seen those side of the road radar displays too. i try to see if it can keep up, but it never does.

 

the OP of this thread fails...

speedometer indicates MPH, your odometer indicates overal total mileage accumulate.

road side radar is not 100% accurate, neither is GPS tracking devices, and neither are speedometers, they are about 98-99% accurate. so 1 to 2 mph off isn't a big deal. when traveling with my garmin nuvi, it was off by about 1 mph from the speedometer, not a huge deal.

 

Lay off the pot man. Your speedometer is fine.

 

hahahaha "accerate"

yeah i have seen the radar things on the road and they're usually 1mph off., sometimes 2....so don't worry about it and worry about driving

 

My speedo is off by 1 mph. GPS says so.
