How to Get MQB ELV CS to Calculate AKL Sync Data

Autel MaxiIMIM508S/IM608 IIandLaunch 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.

How to Solve OBDSTAR DC706 Fail to Read EDC17CP14

OBDSTAR DC706programmer won’t connect to VW Bosch edc17cp14 ECU on bench mode (shown as image below)?

Possible reason and solution:

1.

Some people use the power supply that came with DC706 to connect ECU. That’s incorrect.
The power supply only used to charge the DC706 tablet. Requires an extra better power supply 5amp.

For BENCH & BOOT (workbench) operation, please use a reliable high-power DC regulated power supply (current not less than 5A) to power the ECU.OBDSTAR’s standard power adapter (current 2A) is only used for device charging and is not recommended for ECU. power supply, otherwise communication may fail due to low power of the power adapter!

 

2.

Make sure you bridge a120 ohm resistorbetween CAN H and CAN L and try again.

 

 

If all fails, edc17cp14/cp20 sometimes have High TPROT and not possible on bench. Only boot.
You can remove TPROT, but you will need to do it BOOT mode first to get rid of TRPOT. Then you can go back to bench mode and make read when this is done.

Yanhua Mini ACDP2 Change BMW 160DOWT and CAS4 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 mileageon 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. ConnectACDP 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.
