2006 Volkswagen Jetta Q&A
2006 Volkswagen Jetta Question: Speedometer is off
I would check your road speed sensor data or mph sensor, by using a data streaming scanner, or have a shop do it. Then you can compare the road speed sensor data with the speedometer, to see if there is a difference. Does the car shift normally? Is there a Check Engine Light on. I ask this because this may help you solve this issue. If the road speed sensor was defective, there may be a Check Engine Light, for a speed sensor code. - dandd
do you have the right size tires on the car? tire diameter will affect this greatly. it is also acceptable for a speedo to read higher than the car is actually going by up to about 10%. some questions are does it read "0" when stopped? does the odometer measure miles correctly? - some guy
I have the same problem and I have confirmed it against a GPS and road milieage. My 2006 records a faster speed than it is actuially doing (105 km/hr when it is only doing 100)I brought this up with my VW dealer. They informed me that a this was within tollerance. This error allows VW to end my warrantte at 5% kms sooner, so when I reached by 80 000 km and ended my warrantee, I had really only put 76 000 kms on my car - Pissed. In addition, when one calculates the mileage per gallon, one gets a reading of 5% higher than it really is. - cejma
I just bought the car and drove it 5 times with no issues at all but all of a sudden the speedometer and tachometer?? does not work. Any suggestions?
The speedometer sits at 0 even when im going 60. It will jump up to the correct speed and then drop back to 0. The horn makes no sound at all.
recently I washed the engine in my car shortly there after I began to have problems with the dash board lights the airbag light came on and the battery light flicker on and of and the rpm and speed...
