FWIW, many German cars (Mercedes, BMW, VW, and Audi to name a few) are optimistic by a few MPH about how fast you are going, that said, the odometer and the trip computers are usually dead on accurate.

When I told my dealer that my 2007 A4 speedometer was reading 70 when I was only going 67, they replied that the industry standard is to be within 10% of actual speed, so my speedometer is OK. I realize now that this is the first car in which I have ever checked the speedometer, so all of them have likely had an error in them. At least now I know how to judge my speed.

The reply from the dealer is a bunch of crap. I've had a GPS for years and used it on a lot of American "cheaper" cars. It was ALWAYS within 1 MPH. I have a new Toyota RAV4 and the speedo totally agrees with my GPS while my much more expensive AUDI speedo reads 5 MPH high at 70 MPH. This is unacceptable, I thought German engineers were into precision. When I'm going to bring my A4 in for my 5K check I'm going to tell the dealer to fix this problem. If they tell me that the industry standard is 10% accuracy I'm going to ask for the AUDI specs in writing. I want to hear this from the factory. Also if it reads fast then my 36K miles lease is only 33K miles. That is fraud. I'm going to ask them to explain that.

Like I wrote earlier, every German car I've evern owned or driven has been optimistic in the Speedometer department. I believe they are actually designed that way on purpose and as such, your Audi dealer won't be able to "fix it".

#11 of 26 A4 spedo. by steve150m

I have an 03 A4, 04 S4 and a 01 Jetta all with spedo. readings of 4 to 5 mph high. All were checked with gps. computer in car seems accurate. A good friend of mine who is in the automotive OEM business says by law, spedo accuracy must be +or - 4 percent for cars sold in the U.S. When I compared my odometer to the freeway markers my car only recorded 9.6 miles over a 10 mile stretch. The above speed check was at an indicated 80 mph.

Same problem here. I've owned Audis for years and the speedometer has always matched trip trip computer exactly, on A4'4, A6's, even the current A3 loaner that I'm driving. I recently purchase an "Audi Certified" 2005.5 A4 2.0T 6MT with 32,000 miles on it. With in 5 minutes of picking up the vehicle I noticed that he speedometer was reading high (+5mph) when compared to the trip computer. This was tested w/ the cruise control on at highway speeds of 60-65mph. It was also verified against a roadside radar speed check, and an external GPS unit. All matched the trip computer, and the speedo reads +5-6 mph. The car is currently at the dealer while they try to figure out the problem.

Let me know what the dealer says. I brought my A4 in at the 5k check and told them to fix the speedo also. They checked it with radar ar 40 mph and said to speedo was reading 42 so they did nothing. I've always checked mine at highway speeds and at 70 the GPS says 65. I did the same test with the GPS reading 40 mph on cruise control and the speedo reads 43 mph. I have a ;ease car and if I actually drive 36,000 miles the odometer would say 38,000 and at 20 cents/mile that would cost me $400. So please let me know what your dealer says.

Will do ! I'm interested to see what their "supertech" has to say.....
 
 This has never been a problem before on my 2000 A6 2.7T, or the wife's TT. Even the loaner A3 I'm driving right now is dead on when comparing the trip computer's average speed indicator (in cruise control) to the speedo.

Very unacceptable
I have to be honest I have never heard this problem before
I have never used GPS I guess I have to get 1 any suggestion which 1?
Since you mentioned that toyota rav4 totally agrees with your GPS then what can I say 1 more reason to buy a toyota,lexus cars. japanese cars seem to do everything better
 
Does any1 know if bmw has this problem?

No way !!! I've had the AWD Lexus IS300, and although it is nice I much prefer the way the Audi's drive. We get 5 months of winter in New England, and nothing beats the Audi Quattro for traction in the winter. But, that being said the speedo. issues annoys the hell out of me. Audi is bringing in a "supertech" to look at it tomorrw. I'll keep you guys posted as to what transpires...
