How to Decode VW MQB ELV CS to Calculate Sync Data?

 Autel MaxiIM IM508S/IM608 II  and Launch X431 IMMO Tools both have built-in MQB2 sync data calculator.  With that calculator, users can calculate sync data for MQB NEC35XX locked all keys lost programming.

But to calculate sync data,  CS from each cluster, ecu, gearbox (if automatic),  ELV  (if keyless)  are required.

The CS code from ELV module is difficult to get. Many people ask how to read CS from MQB ELV.

Xhorse VVDI2 just released software V7.3.7.

*** 2024-11-19
*** Require firmware V7.3.5
===== VAG V7.3.7 =====
1. Support decode/update MQB-ELV data read by Multi PROG
2. VW NEC+95320(873B) type: Support decode immo and repair KM with FLASH+EEP
3.Support Brazil Instrument immo G4/G5(Gol/Fox/Saveiro)

Hyundai Kia MB91F061 MB91F067 Mileage Correction Tools

 Customer question: 

I need mileage correction in Hyundai i30 2018 dash with fujitsu mcu MB91F061, a Kia Sorento 2016  fujitsu mcu MBb91F067 and SPORTAGE 2020 with Renesas mcu RH850. What is the best tool to do this?

 

Several tools exist to correct mileage on fujitsu mb91f061/MBb91F067 or renesas RH850 mcu clusters.

SMOK: If you have SMOK then use their microcalc2 to calculate the new km. A friend of us did a 2016 it was MB91F061BS did with SMOK.

DP4: Diagprog4 can do it via Obd port.

Enigma:  Enigma makes them all on bench. Simple 5 or 6 wire connection and done.

iProg+ original:  Iprog+ Cardiag script can do this, Honda, Hyundai, Perodua Axia, Toyota Rav4, Toyota Innova, Kia
That is the best script for Fujitsu Mcu MB91Fxx series. But it cannot do RH850 yet.

X-tool:  Take the cluster out of vehicle and with x-Tool under the Fujitsu Spansion (Denso adapter) section choose Kia Sorento 2015+ Mb91f067 exact same processor and mileage location as Hyundai santa fe . Take off back cover and solder on 7 wires from Denso adapter as showing in diagram and use to write flash and eeprom I posted and change mileage same under Kia Sorento 2015+Mb91f067.  Follow instructions and Solder on the 7 wires on the sante fe cluster the points are clearly marked ,uin,uout,gnd,mdo, rstx,ign,gnd. Read your original flash and eeprom save it and then write the good flash back.

CG100X: CG100x does correct mileage for Hyundai Fujitsu Mcu MB91Fxx series. But it cannot read and write Hyundai 2019- RH850 cluster yet.

for cg100 use the pro v2 line

wire 4 = uout

wire 3 = uin

wire 7 = rstx

wire 6 = mdo

wire 12 = gnd

wire 1 = 5v

wire 2 = ign ( if you use kia k3 2016 script to read)

use the programmer to read dflash and post for modification because you don’t have a script for kia cerento in cg100 or use kia k3 2016 mb91f067 connection its same dash.

 

 

Yanhua Digimaster 3: D3 will correct mileage for Hyundai Sonata 9 MB91F062BS, IX25 MB91F061BS, Verna MB91F061BS, CELESTA MB91F061BS

For MB91f067, Digimaster iii also does it, go to Programmer-> select MB91Fxx. D3 does not have have wiring diagram for this. Need to find diagram by yourself.

 

D3 cannot do 2019- clusters with Renesas RH850 MCUs yet.

Yanhua ACDP2 Change BMW 5 Series Mileage

 Yanhua Mini ACDP has an interesting feature that will allow us to change the mileage on quite a few BMW vehicles. ACDP2 is capable of correcting the mileage on all the F-series BMWs.

Here we will show how to change/correct mileage on a BMW 5 series using the ACDP2.

 

What you need
Yanhua Mini ACDP2
BMW CAS4 module

Module 4 for BMW 35080, 35160DO WT mileage
Clip adapter
gloves

 

Make sure you don’t leave any fingerprints, use gloves during the process.

The cluster is showing 146861 km. We are going to test it and take it back to 145861 or somewhere very close to that.

The actual process for the BMW vehicle is a bit more complicated than on other vehicles. It requires the instrument cluster to be processed also the CAS module. The security module also needs to be reset.

 

1. Change the mileage on the cluster

We start with the instrument cluster. We need to take it apart.  Then find 160DOWT chip. Make sure the contacts are clean.

If the instrument cluster has been updated to the latest I -level (to the latest software version),  mileage correction will be almost impossible to do.

You might want to downgrade the software of the cluster in a situation like that one.

Select BMW->M35XX-> 160DOWT->Backup data

Connect the ACDP device with M35XX adapter (comes in ACDP module 4) via eeprom clip adapter.

Made connection. It detects the pins. Back up file successfully.

Select Modify Mileage. ACDP shows mileage 235,999km. Input mileage you desired: 234,330km and save.

Finish correct mileage for cluster. Reinstall cluster.

 

2. Change the mileage on CAS4 module

We move on the CAS4 module. Connect ACDP CAS4/CAS4+ interface board with the CAS4 module.

Make sure that some of the contact points are making contact as they should.

Select BMW->CAS4/CAS4+/ ICP mode-> 9S12XDP512 Mask 1L15Y->Reset Mileage->Reset Mileage (Auto)

Reset mileage automatic as an observation all of the software is running somewhere on a server. Make sure you have a good connection to the internet.

Two LEDs are on showing that you have contact good contact on that side of the board.

Decrypting chip

ACDP read mileage and auto reset mileage.

Reset mileage on CAS4 module successfully.

 

Install CAS4 module to vehicle. Check the mileage. It is very close to the value we want it to be.

Connect Xhorse Multi Prog with Godiag GT107 or GPT Cable

 Some users reported they had difficulty connecting VAG DSG gearbox TCU DQ200, DQ250 etc with Xhorse multi prog.

Here we will show another easy way to connect multi-prog with gearbox TCU and engine ECUs.

 

You will need Godiag GT107 or GT107+ DSG gearbox adapter (for TCUs) or Godiag GPT Bench Boot adapter (for engine ECUs).

To connect multiprog with both adapters, you also required to purchase a Godiag G-V ecu cable converter.

With these cheap godiag adapters, you will connect multiple TCMs/ECUs that multi prog will do. You can get this kit as a whole. Check full godiag TCU ECU kit.

 

These are some wiring diagrams.

 

Wiring diagram to DQ200 gearbox

Wiring diagram to DQ250 gearbox

These set will also read other VAG gearbox TCUs. Check coverage in Multiprog software.

They will also read engine ECUs on bench or boot mode.
