maxed out at 621358 miles, 1 gigameter limit?

[alphaseinor]

Okay, here it is... quite possibly the highest mileage 2003 I've ever seen... and the odo is stuck here, trip still works... tracking mileage with the 2000 mile marks on the trip odo.

sorry for the large photo... hopefully it will show up correctly...
if not...

Any ideas on making it move again? already tried vagtacho and vagcom methods...

oh and a gigameter is the getting close to the diameter of the sun... and a million kilometers or... 10^9

Wow. That is pretty awesome. You should still have about 12 -13 miles left before the 1,000,000 km mark. How many miles of those are yours?

 

[alphaseinor]

it's actually closer to 650,000 miles ( a little over...) the trip odo is mine since sunday.

 

[fase2000TDI]

The coolest thing about that is over 600,000 miles it likely used less than 13,800 gallons of fuel. $40,000 of diesel at today price.

 

[biopete]

you should tell vw and maybe they'll put in in their museum one day. At least they may want to give you a better odometer that can count higher like this guys's 240D that got 4.6 million KM.

I was just thinking a 1,000,000 KM = 621,371.192 miles so your odo should have gone a bit higher before it stopped at 999,999 km.

 

[alphaseinor]

I'll have to do a scan again and look at the actual value stored...

at least the trip odo works.

now does this constitute beyond mechanical limits?

3 engine rebuilds plus original *(thats if it was still original when he got it at 500K) but even it was 4 engines thats still way impressive 1.15Million KM / engine

 

[flatlanded]

It's gotta be a VW thing, my 95 went from 299,999kms back to zero...

 

[Lug_Nut]

That was an A3 thing, not a VW thi....ummm....idiosyncracy, that's a better word.
A VW Thing would be the Kubelwagen

The B4 of the same era don't revert back to zero after 300,000 units (miles in the USelessA, Km in Canukistan apparently) the way the A3 do.

Still, the coincidence of 621,000 miles being so close to a million Km is enough to make the association plausible.

USelessA

I happen to own a 240D, and I can assure you the tachometer does not go to 4.6 million kilometers. As a matter of fact, the odometer/speedometer has broken two times. It fails far more often than the engine, which is still running strong. We have lost track of mileage though. It is somewhere between 400K-500K miles, I presume.

 

[740GLE]

what about the P1800? now thats a great ride worth putting that many miles on

 

[manual_tranny]

mmm... that would be nice

 

[alphaseinor]

If I recode to read KM (canada) in the instrument cluster it reads all 9's (999,999)

 

[Steve99]

The odometer could technically go to 655350 miles before running out of a way to store the value in the cluster but I guess they limit it to 999,999km's which is why your miles stopped early.

 

[JetPuf]

So will you be making it to TDIFest with this beast??

 

[jcrews]

If the user storage area for the ODO is in an unsigned packed decimal format, the limit makes perfect sense.

999999 requires 3 bytes of stroage, or 4 bytes if signed: 0999999F.

3 bytes in binary format would be FFFFFF, or 16.78 million.

 

[Steve99]

Its actually only 2 bytes, stored in miles, multiplied by 10 for the readout.

 

[alphaseinor]

the adaptable value is 65535 (X10 km), that's a limitation of adapting (two byte), there could be an artificial limit in place in the programming so it doesn't "roll over".

Once it goes past 655350km, I doubt you will be able to readapt (even with vagtacho), but it will still count upwards

 

[Steve99]

I guess they had to find a way to do it with only a 16 bit counter. The least significant digit is calculated/stored differently then the other digits in the odometer

 

[alphaseinor]

The adaptation is only 16 bits, I'm sure it's a 24 bit or a 32 bit value, but has a max value of 999,999 for the counter loop. The trip odo still works, so at least I can keep track of it.

giggity... unfortunately not, I've got some plans for a wedding to go to... I tried to get them to PDX for the wedding but NOOOOOOO... they had to smash my glory so they could get married...

 

[Steve99]

Sorry, its all only 16 bit. I can show you the cluster eeprom files if you want to see exactly how its done/stored/calculated.

 

[cmitchell]

I would like to see photos of the car... just to see how it held up!

 

[alphaseinor]

I've got the carfax and autocheck and it shows a consistant 100,000 mile increase year over year, stopping at the 628k mile mark...

If you can show how it's done, stored, calculated that would be great, maybe I can modify it for a rollover scenario.

 

[jcrews]

Sorry, its all only 16 bit. I can show you the cluster eeprom files if you want to see exactly how its done/stored/calculated.

I'd like to see it. Or send me the file. I don't know what I did with some cluster memory I had earlier.

 

[Steve99]

I will see if I can find a file I can share this evening. Or if you find one jcrews post it somewhere and I will tell you the stored mileage and how I got it.

 

[kooyajerms]

Contact Derek, he may know a couple things with being able to rebuild clusters (some of them). dewhite2485@hotmail.com

 

[ymz]

So the odometer doesn't go over 621358 miles ???

Car's obviously a lemon...

(I guess our 2003 is only just broken-in at 618990 km...)
