Speedo Inaccurate

[logger]

well, no speedo is 'out by 10kph' - it's out by a percentage.

Yeah thats right. There are (for the MK5) 7 known distance multiplier settings ranging from 21848 to 22532 impulses per KM, which gives a spread of 684 representing ~ 3%. So If your digital and analog speedos overread by 6% as mine do, I could only expect to halve the intentional error in both which I have elected not to do, for reasons already stated.
Out of interest Coreying, do your analogue and digital speedos match like mine or do they differ? Obviously there is always going to be some paralex in the analogue dial presentation which would account for a 1% or so.

Sorry - you're correct, the Passat hasn't been updated yet, only the Passat CC.

But the answer to your question is no, all recently updated VW's have done away with the '3 dial 2 display' aircon system.

Yes they can but as Coreying said they most likely won't.

I will put the pressure on them.

Let us know how that goes

Buckleys chance I would say.

In my Polo GTI, the analogue speed is out by 7% (based on the resetting of trip metre whilst on average speed).
I don't have a MK6 Golf yet, but the two GTI's I've driven have been 6% out between the digital display in the MFD and analogue speed as you've observed.

I will put the pressure on them.

It's been an issue since at least the launch of the Mk5 some 6 years ago. I don't like your chances.

It's not that hard to just deal with it, haha.

I can deal with 2%, not 7%. If this is a common problem with VW, then it is poor form on their part. Every other car we have owned, and there have been a lot, don't have this issue.

I respect others that don't find it an issue, but I want to see as close to my actual speed as possible and I will decide if I am driving at or below the speed limit.

Cheers,

Dave - this is not a 'VW Problem'. It is something that ALL car manufacturers are being ENCOURAGED to so do by governments and regulatory bodies all around the world.

Since the population tend to drive 65 in 60 zones, 110 in 100 zones etc, the purposely designed 'error' in the speedo means that you're then basically doing the speed limit.
The other thing is that since speed cameras are giving less than 3% tolerance these days, and your 'seating' position can also introduce an error that you read an analogue speedo, the higher tolerance also means you have less chance of being booked for speeding.
There is then the issue that changing from 17" to 18", or even worse, 19" wheels and tyres (which is allowed under current laws) can also introduce up to a 1.8% error and the speedo has to allow for that.

So please do not critism VW for a 'problem' which is not a problem at all but which is regulation.

Come on guys just enjoy your G MK6's and get over the overread.
