HEELP !! My mileage now shows ERROR - after playing around with Vag K-Can Commander 3

[Cornholio]

As topic says, I have a Vag K-Can Commander 3.0 borrowed from a friend. I took it in the attempt to read out my SKC code from my cluster so I can add another key to my car ( I only have one ). My cluster model is BOSCH RB4 ( so not a VDO ). Commander was not able to get that code read out. However the mileage read on the commander was way off : showing something like 428 milion km. My in car cluster was showing the real mileage value : 248.000 km, so I decided to change the one in the Commander. After hitting SAVE, dash turned off-on for 1 sec and then instead of some km, I have ERROR in my dash. Trip mileage works fine, although it started from 0.0 after this little issue. Everything else seems to work perfect with the car. What do I do to get rid of that ERROR ??

Some guy in a forum, said he replaced the first line in the whole code with : 000000: 54 D2 9C BF A7 EC 0F 64 80 96 FB 48 0A 96 25 03. That solved the error problem for him, but that also put a 159.000 km on his dash. To be honest I wouldn't exactly mind to have that as long as I get my ERROR code outta there but right now I am quite afraid to do any more adjustments or code alterations as I am fully aware that I can have my immo not recognise my key or even worst things....

I would really appreciate some help in this matter.

Thanks so much.

Sell it now with 159000km... LOL

Holy crap...is it a chinese version of Vag K+can? Noo ...Noooo....I had that thing. Cost me $110 and it's in the garbage. When you tried to set the mileage didn't a window pop up in broken english notifying you that the procedure "might result in destroy eeprom"?
DO NOT WRITE ANYTHING TO THE EEPROM!! Just don't do it unless you have the 100% right tool to communicate with the RB4, that chinese tool isn't reading the actual eeprom as it's encrypted in the RB4 cluster. Since your mileage is already in KM's divide the number of KM's by 10 (so 248,000/ 10 = 24800) and enter that into the box and reset mileage. That's typically how the interface expects the mileage to be entered....I don't know if the cluster will accept that, but it's REALLY likely that writing new un-encrypted values to the eeprom will brick your cluster- or worse, the wrong coding can turn your fuel pump or fuel injectors on permanently and possibly even set the airbag off.
If you can read the eeprom i can tell you where the SKC is encrypted/stored in the eeprom...i have the info somewhere.

lol I dont intend to sell the car in the near future :) However I need to get rid of the ERROR in the dash... I would probably settle for 450.000 too instead of that error :P How can I create that first line of code with my correct 248.000 km ?? Well, I dont even know if the line editing thing works or not in the first place.

That's why I could use some info from some of you guys.

LE : I think I have my explination which worries the sh1t outta me :(

This came off the Vag K-Can User Manual ! :((

if the car was showing the right millage in the first place why did you change it? not very smart on your part to purchase such a tool and then just start changing things that you THINK look wrong in the programming.

in the states trying to change the millage is a huge no no legality wise.

wish you the best of luck but i'm not holding my breath, hope you have some extra cash for a new cluster.

[rollerton]

Whatever you do, DON'T USE THAT TOOL TO WRITE THE EEPROM! It's very likely to make your cluster worthless.
Seriously. Vag K+can is NOT the tool that does that. The tool you need is Vagdash com+can.
You could try disconnecting the battery or clearing the codes with VCDS- in an Immo3 car your original mileage is stored in the ECU also. It might work.
The ONLY thing I would do with that, and at your own risk, is like i said, divide your mileage by 10 (248000/10) and enter that figure into the correction (24800). It's not likely to do any more damage than is already done.

You don't need the SKC to add a second key, now your cluster is effed up.

Cmon, u are in Romania, pretty much any autoshop should be able to change your mileage to whatever u want.

romania must be a verry disonest and dangerous place to live then...

[Antekaudi]

Did you read the base file and save it before you started playing with the odometer ?

[kwimberly]

All your kilometer are belong to us.

[BASARAB]

romania must be a verry disonest and dangerous place to live then...

LMAO, all eastern Europe is like that. Even in Western Europe (Germany for example) they roll the mileage back, because its not a federal crime like here in US. I am not even talking about third world countries.
When u buy car nobody really looks at the mileage, u only check the year, because "everybody knows that everybody rolls the mileage".
Even here in Metro Detroit there are few shops, which will do that for 200-500 hundred (I even saw someone advertising on CL lol).
U must be living in a bubble.

[Cornholio]

First of all let me tell you why I decided to play with mileage. When I first purchased the car I checked it with some dude's interface to see if it has the correct mileage and it showed us the 428 milion km so I figured that HAS to be incorrect so I left to that. Now that I saw the same thing in the Commander I thought : OHHH GREAT, here's why. So I decided to have that value show the correct 248.xxx km so it would start showing the correct mileage BOTH on the dash and on any interface one would use to check in the future. I haven't tried to input a LOWER mileage in order to mislead anyone as I don't intend to sell the car at least for quite a few years from now on.

Offtopic: I think that 95% cars purchased from GERMANY have their mileage rolled back. Although I know in GERMANY this is very much illegal, they still do it. Anyway this is not relevant in our case here as I didn't try to go lower :)

From what Commander manual says, I need to keep the Cluster fuse pulled off for a few minutes and then trying to log-in on it again. I kept it off for 15-20 minutes today but didn't have the time to re-log as I had to leave for work. I will get back home and try to log-in again, this time using CRYPTO version as the first choice and see what happens. I may be able to read the correct code plus mileage adjust.

Will keep you guys posted and I appreciate any input from anyone that knows anything.

LE : Fuse pulled out for 20 mins - didn't help.

How can I tell for sure if the Cluster is RB4 Crypted or just RB4 ?

[rollerton]

I think Rb4 are all encrypted after 2001 in the A4.

[pati]

Heloo everybody! I can tell you better sitauation ;)

Now I have A4 2001 with crypto dash to repair it after that when somebody who tried to repair non funkcjonal speedometer, conected it to commander I don't know witch version.. I don,t know why he did it, but after that def appeard. He tried to repair it and he didn't do it, becouse of no dump written to file. After that my client gave him a cluster with ECU with unknown pin code, but he lost a chip 24c08 after desolding ;D. Now i have oryginal RB4 D25 with known pin and but with DEF on day milage odometer, and i think D36 (kolor MFA) without memory. For me the situation is unreal but it happend. Do you have any ideas how to repair the def? I tried to program other dumps to D36 but def appeard. I havent got any other RB4 D25 files with known pin code. Thanks for any ideas!!!

//note to self - never buy a used car from an Eastern European country.

I am pretty sure u know about it more than anybody on this forum, so u probanly wont get a good advice

[pati]

Really do you think so?? After one post... thanks. Good advice is that to bay another one with known pin code? Isn't it?? True is that, i heve never repaired it yet. If it's possible i can send a dump with it (known pin etc).

[rollerton]

Why desolder a chip on the cluster? if you have the proper version of Vagcommander and can edit the eeprom you can turn the Immo off.
How do you know you have the right PIN? If you have the right PIN then adapting the cluster is pretty straight forward.
I am 95% sure Vag commander cannot read the PIN from Rb4 clusters- maybe euro/ candian would work. I think only Vagdash com+can can do this.
If you can dump eeprom you can decode pin from the proper Hex address.

[pati]

I have only the 1.4 version and it works good but not with RB4. I didn't destroy the dump but somebody before me!!! And i have pin but there is def on the display and i didn't try to adopt it without of the trouble. Tommorow I will try.

Ok i Have now the another one of A4 (olso D25) but the dump don't work too in the first A4. After that I experimented with the second one. I read the dump with known pin kode and after that i changed it in ECU end i adapted the cluster to ECU with diffrent pin but the some vin and immo number. It went good, and after that ( i did it about one hours ago so i heven't got to much tiime to think about it) I compared the two files with only pin diffrent. After that i think the pin is written in lines: 40, 120, and 220 in two bytes in each line (xxx6 and xxx7 hex but i don't remember now). This is that what I todey observed. It's hard to work with it because my commander is reading but only about 50 lines of 16 bytes pages, and somtimes less and stop transmission. So i have to desolve the EEPROM when i want observe any changes. If any body know somethink more i'm open for ideas. Good of new year!
