Speedometer on Jetta is off at least 5-6 miles per hour and the clock keeps gaining time...........what are the solutions??? Thanks in advance > Speedometer on Jetta is off at least 5-6 miles per hour So how fast is it going when it is parked? :-) That is adjustable with a VAG-COM. You need to find someone with one. It is a computer interface specific to WV's Most shops will not have one unless they specialize in WV's. Remember that it is normal to indicate about 5% over the actual speed. They do this to assure that if it is off, it will not end up causing you to get speeding tickets, you get to do that on your own. BTW how are you computing that 5-6 mph error? > and the clock > keeps gaining time...........what are the solutions??? The clock sounds like a time warp problem. Frankly I have no idea about it. Could you wife be setting it ahead in an attempt to get you on time? > Thanks in advance  SignatureJoseph Meehan Dia 's Muire duit In news:483360a8$0$7070$4c368faf@roadrunner.com "Joseph Meehan" <sligoNoSPAMjoe@hotmail.com> wrote: > BTW how are you computing that 5-6 mph error? In the range of speeds I normally drive (30-80MPH), my '02 Passat's speedometer reads 3MPH higher than my actual speed as shown on my GPS receiver. My wife's '02 Saturn reads dead on. I've had people tell me that the high reading is required by some German law. This makes little sense, so it's probably true.

This makes little sense, so it's probably true. it is, more or less. They are allowed some small error fast, but none at all slow. I believe that 5 MPH at normal speeds is probably pushing it, though. I don't remember exactly what the law states is an allowable error... nate Signaturereplace "roosters" with "cox" to reply. http://members.cox.net/njnagel > > <sligoNoSPAM...@hotmail.com> wrote: > [quoted text clipped - 16 lines] > -- > replace "roosters" with "cox" to reply.http://members.cox.net/njnagel And I thought it was just mine that had this issue... I have a 2006 Jetta and it's about 5 high at an indicated 60, around 6 or 7 high at an indicated 80. At first I thought the GPS was off, but had two units with the same numbers, and then consistiently got clocked by one of those "your speed is" signs at the same indicated by the GPS. Oddly, as far as I can tell, the odometer is still pretty accurate (gps agrees with it, and a bit of dead reckoning at highway speeds over long periods matches up. 170 miles till X on the Caltran signs agrees with the odometer reading upon arrival). Can't say I've been having an issue with the clock though. Anyone brought this up with the dealer when taking it in for a service? I'll mention it next oil change and see what happens. -Chris If you check the odometer on your next 100 mile highway road trip report if the odometer is correct. Many people with cars from the 03 era report the odometer is dead on but the speedometer tends to report about 5% fast. 10% fast would be rather annoying. >> > <sligoNoSPAM...@hotmail.com> wrote: >> [quoted text clipped - 37 lines] > >-Chris >it is, more or less.

I don't remember exactly what the law states is an >allowable error... In some countries, no error on the slow side is allowed even with the largest possible tires that could fit in the wheel wells. Which would explain why the speedometer reads fast with OEM wheels and tires. Signature------------------------------------------------------------------------ Timothy J.

But some cars had the cluster recoded to correct if it was faster. As for the clock there may be a tech bulletin or you may be a new cluster. Dealer should be able to help out. > Speedometer on Jetta is off at least 5-6 miles per hour and the clock > keeps gaining time...........what are the solutions??? > Thanks in advance > Speedometer on Jetta is off at least 5-6 miles per hour and the clock > keeps gaining time...........what are the solutions??? > Thanks in advance All designed to make it last longer. <:) |
