Tips:

In the case of not disassembling the meter, do not know what the CPU is, can be judged by the odometer number.

Both MQB48 5A and MQB49 5C has 1401, 1402, 1407 dashboard numbers. The menu is different, and the algorithm is also different.

How to tell 5A and 5C cluster:

The best way is to scan the key if you have one. If no keys, you can find out which is which by finding those little EEPROMS as on the picture.

EM = 5A: PCJ = 5C

Verify the chip on the board.

If it marks EM, then it is 5A dashboard.

If it marks with PCJ, it is 5C cluster.

Connection diagram:

Mini ACDP APP/software has the corresponding diagram and instruction inside. It’s easy and safe to connect the Yanhua Module 34 interface board, dashboard and ACDP 2 properly.

For example: Lock fastening R7F701407 interface board installation

1.Push all PCB lock fastening on the interface board to the unlock position.

Find the interface board installation area on the instrument, according to the visual positioning mark on the interface board.

2.Find the correct positioning holes of D1, D2, D3 on the instrument.

3.Check that the D1 and D2 positioning pins are completely aligned with the D1 and D2 positioning holes of the instrument, and ensure that the PCB lock buckle is completely aligned.

4.Finger down pressure interface board, push the PCB lock buckle to the Locked position to lock the interface board, installation is done.

5.Confirm again that the interface board D1, D2, D3 positioning pins are completely aligned with the D1, D2, D3 positioning holes of the instrument

Operation guide:

Select VW>> VW MQB IMMO>> MQB49 (R7F7014xx 5C)>> ICP ODO (R7F701401, R7F701402, R7F701407)>> Interface board number

There are two modes: Auto mode and step mode.

Use Step mode to read ODO data and save the data

Then use Auto mode to detect Pin, identify chip info, and then input the target mileage to write

Wait a moment till the mileage correction is complete.

For example: MQB RH850 5C R7F701401 KM
