Question:

Is it possible to add new keys or do all keys lost to VW MQB RH850/V850 Cluster by Launch X431 tool?

Here is the answer from EOBDTOOL.co.uk engineer:

Yes.

Currently, Launch X431 X-Prog3 Key Programmer not only can work with Launch RH850 Adapter to read and write Renesas encrypted RH850 R7F701xxx 48-PIN, 80-PIN, 100-PIN, 144-PIN, 176-PIN MCUs (click here to review), it also can work with X431 IMMO Plus, X431 IMMO Elite, IMMO Pro, IMMO PAD, etc to program key to some VAG MQB RH850/V850 R7F7014xx 5A clusters as follows.

• R7F701401
• R7F701402
• R7F701404
• R7F701406
• R7F701407

Note:

1.Add key and all keys lost are supported. All keys lost require sync data.

2.Mileage correction is not supported.

The corresponding wiring diagram can be checked on the Launch X431 Tablet.

Some clusters require removing some components (resistors) or cutting wire.

X431 X-PROG3 comes with an integrated MQB2 calculator.

Under the 'All Keys Lost' function, there is an option to 'Obtain Sync Data'.

With this built-in MQB2 calculator, you can retrieve the sync data for free. You will need to collect the Component Security (CS) codes from each module: the instrument cluster, ECU, gearbox (if automatic), and Kessy (if keyless).

• Instrument panel CS code: 16 bytes
• ECU CS code: 16 bytes
• TCU CS code: 16 bytes
• ELV CS code: 16 bytes (if present)

Once you have gathered these, you will be able to obtain the sync data for free.

In addition, CG100X supports mileage correction for MQB RH850/V850 5A and 5C clusters.

Xhorse Multi- Prog/VVDI Key Tool Plus Pad supports MQB RH850 5A clusters IMMO programming.
