Hello, Took a trip down to the USGP last weekend and had my GPS on the dash. I noticed that my speedo was off by +4-5mph at varying speeds. Is this "normal". Thanks.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

It's normal. Search on this topic and you will find a lot of threads on this issue. U.S. made cars are a lot more precise, while German law is more loose. Speedometer shows 4-5 miles higher speed

My speedo is about +2-3mph @60mph.

Same here....about +3-5 at 60mph

Mine is absolutely spot on the nail. I can prove it because I also have a GPS camera detection device that displays my current speed. It is always the same as my speedo.
