I have a weird problem with my audi a6 c7,

When i'm cruising down the highway with 100km/h and activate the cruise controle, the cruise controle speed says i'm driving 106km/h.
It's not just with 100km/h but with all speeds the cruise controle speed is always 6km/h faster than i'm actually driving.

There are no fault code's active.

What is showing the 100km/h speed?

I get a similar difference between a GPS device and the speedo/cruise in my car - mainly because by law speedos have to over-read by between 0% and 10% (i.e. they must not read too low) and typically over-read by around 5%.

The speedometer shows 100km/h (the digital one in the center as well as the one with the needle) when i activate the cruise controle it shows 106km/h ( the green text that pops up when activating the cruise controle)

That is indeed quite strange.

Please post an Auto-Scan so people can see what your car is made of and how things are configured.

My Passat:
Cruise control set to 100km/h (visible on the MFD).
Speedo needle showing cca. 101km/h (one needle width after the 100 mark).
Phone GPS reading 93 or 94km/h.
It's been like that since day 1.

6-7% is within the allowed tolerance of 10%, most average around 5% - so absolutely normal.

I would not complicate on the 6 km/h difference. The main speed gauge always displays some 5 % higher speed than more accurate meters - GPS and other car electronics.
This was done intentionally in the past as speed was measured by electromechanical means with relatively low accuracy, judged by present standards. They just added safety system error to stay on the safe side.

So to be clear i added a photo, my questions is about the difference in speeds in the centre of the display. my actual speed and the cruise controle "set" speed.

Have you verified your "actual" speed by using an independent GPS device (e.g. smartphone, etc.)? This would show which one of those speed readouts is closer to true speed.

the actual speed is closer to gps speed, the CC set speed is 10km/h of

Is the difference always 6 km/h? What happens if you set it to a slower or faster speed?

yes, it's always 6 km/h with every speed

Sounds like a software bug of some sort in the car.

Your ECU has software version 0002. There are updates to 0003 and 0004 available.

If it were mine, I would pay a dealer to run a complete SVM session on this car. You have other modules that could clearly benefit from this as well, e.g. the belt pre-tensioners.

It's normal for some cars to have their speedometer read a bit high, for safety and regulatory reasons. The car always knows how fast it's really going, within the bounds of mechanical possibility. It's only changed for driver display. My old B5.5 Passat and my Phaeton have the offset, but my 2018 Golf R doesn't... but in other markets the Mk7 Golf does seem to have a displayed speed offset. I don't know precisely what countries have what rules.

I have to deal with this sometimes for openpilot. I don't think there's any worldwide shipping configuration where the car displays two different numbers once it reaches steady-state cruise: both the displayed speed and displayed CC setpoint should present your true speed, or they should both be transformed/offset. Something is wrong here.

yes, it's always 6 km/h with every speed

Given that you're seeing a constant positive offset at every speed, this does sound like problem with software/regulatory offset configuration. But how and why...

Do the "Revision" and "Serial number" fields appear like that in your original Auto-Scan, with the "2" between them? Or is that a copy/paste oops? If your instrument cluster puts out truncated/corrupted spam when asked for its Revision, that's bad, mkay? See this example scan with a non-garbage Revision. It means the EEPROM is corrupted, possibly due to tampering. Do you know the full history on this car? Is it possible anyone has used non-dealer/locksmith tools to match new Immo keys, or to defeat Component Protection (not sure if either are actually applicable to this car) or used sketchy tools to tamper with the odometer?

If the Revision thing was just a copy/paste issue or a fluke, then take a look at the Coding value. Look for anything related to regions of sale (Europe/RoW), markets, countries. Make sure it's set correctly. Failing something in 17-Instruments, look for the same sort of thing on 01-Engine, which controls the CC setpoint and relays it via CAN for the instrument cluster to display.

It's normal for some cars to have their speedometer read a bit high, for safety and regulatory reasons. The car always knows how fast it's really going, within the bounds of mechanical possibility. It's only changed for driver display. My old B5.5 Passat and my Phaeton have the offset, but my 2018 Golf R doesn't... but in other markets the Mk7 Golf does seem to have a displayed speed offset. I don't know precisely what countries have what rules.

I have to deal with this sometimes for openpilot. I don't think there's any worldwide shipping configuration where the car displays two different numbers once it reaches steady-state cruise: both the displayed speed and displayed CC setpoint should present your true speed, or they should both be transformed/offset. Something is wrong here.



Given that you're seeing a constant positive offset at every speed, this does sound like problem with software/regulatory offset configuration. But how and why...

the "2" is in every scan i have from this car. i do not know the full history of the car. What i do know is that it had front end damage before i bought the car 2 years ago

Well, that's not good. Unless @Uwe or @Eric have other thoughts, I'd consider your instrument cluster to be highly suspect/potentially damaged.

You can and should (I would!) hunt around in the Coding options anyway, as I outlined above. Maybe this particular symptom is fixable.

I just looked in a scan from my car i owned before this one, And with that car there is a 1 instead of a 2 (never had any issue there). I have a limmited vin vcds. is it possible the 1 and 2 stands for the number of vins have been used?

It's possible that it's not a real problem, though I didn't see it when I looked at another example car. That's why I invited comment from the VCDS head honchos.

Nah, that shouldn't have anything to do with it.
