Who's running the highest miles?

raptor2004

My 2004 Yaris is only on 122k miles. 

Engine is still sweet as a nut. 

The only thing I had to replace outside of consumables was the alternator (bearing was going) which cost a pretty penny.

What is OBD 11/VCDS ?

Yes I would like to know the mileage
It stopped working after I pressed button to zero trip, message came “ Error “ after that it stopped showing mileage.
The odd thing is when it’s very cold in winter you can see faintly the trip mileage .

OBD2 is the vehicle's On Board Diagnostic system.
It's the industry standard way to read the cars electronic brain/brains (ECUs).

VCDS is short for VAG-COM Diagnostic Software.
It's a manufacturer specific piece of (Third Party) software that runs on Windows that allows you to read the cars electronic brain/s via the OBD2 system.

You would need to buy the adaptor that works with your vehicle and the VCDS software, plus the VCDS software.

This adaptor fits into the car's on board diagnostic port (it looks like a old Scart Socket that you find on the back of VCRs and TVs under your dashboard somewhere) and connects it with the Laptop/VCDS software.

It will allow you do/see pretty much what a VW dealer would be able to do/see inside the car's electronic brain/s, including reading the mileage stored there.
It's only your mileage display that is broken, the mileage is still recorded and stored.

The adaptor and software can be a bit pricy just for a mileage read (though I think there is a Lite version for free, but functionality will be very limited) but most VAG forums have local owners that have the kit and would happily do a quick scan for you for a "drink" if you took it around.

Also, as VCDS is quite similar to the manufacturer specific software main dealers use, lots of VAG independents will use it as well.
They'll often have a set fee for a scan of the ECU based just on the time it takes to do it.

Before you start to read up further, most cheap, generic ODB2 adaptors and cheap/free software will not read the mileage that is stored.
They will only usually read the first set of generic diagnostic trouble codes (DTCs) of the engine ECU (generic P codes), if you can get them to work in the first place.

DTC's are usually split into two

Generic all manufacturers use. 
And
Manufacturer/model specific.
Each code usually come with a further set of sub codes to further help with diagnostics.

There are more than one ECU within a modern car, these days there are a number of them all with their own fault codes.
Engine DTC's are usually P codes.
Chassis (like ABS) are C codes
Body are B codes.
Communication are U codes. 

Obviously to delve into the mileage stored you need something that can reach.

Just one minor point is that when I referred to OBD 11 I meant OBD eleven which is aimed at VAG cars (plus some recent additions) and was a little cheaper than VCDS but now has some sort of subscription model. That's the tool I use on my two VAG cars as it's good enough for most things.

You're right though that a lot of forums have people who will run a scan for a pint.
