VVDI PROG VW Polo MQB D70F3526 Try Frequency Failed Solution

 How to read immo data from a Volkswagen Polo of cluster using the Xhorse VVDI PROG + MQB48 Solder Free Adapter? Initially, I’ve met an “Try Frequency failed(00)” error that prevented successful data extraction. But after some troubleshooting, I was able to identify and fix the issue.

The following are the procedure:

Open the VVDI PROG software,

Type: 5-DASHBOARD

Brand: VOLKSWAGEN

Chip: MQB-LOCK(D70F3526)-READ(ADAPTER)

Follow the diagram to install MQB board & the XDNP79 solder-free adapter, then connect to VVDI PROG and 12 volts power.

Click “Read”.

Unfortunately, we have an error here.

It says:”Try Frequency failed(00)”.

It took me long time with so many hours to find the solution for the error.

And now it’s very easy.

Just take a separate wire to connect the VVDI PROG for 3.3 volts and clamp FLMDO pin on the adapter.

Make sure you don’t touch any other pins.

Let’s try to read again.

If all the pins are touching correctly the board now, we should read the immo data.

This may take about 10 minutes……

Reading success.

Save the data file.

Disconnect all the 12 volts & VVDI PROG, let’s connect to VVDI2.

Open VVDI2 software,

Key learn >> MQB platform instrument immobilizer >> Instrument with locked NEC35xx(MQB48, VDO/JCI)

Decode immo data >> Yes >> Upload the saved file

Press OK to save MQB48 immo data file.

Now you’ve successfully got the MQB immo file, it can be used for key adding.

VVDI MLB Tool Calculation Failed Error Code Solution

 Problem:

One of our customers tried to add a spare key to Audi Q7 2020 with the Xhorse VVDI MLB Tool. However the tool failed to collect key data.

Error “Key data calculation failed”.

Common Issues with Collection Failures

• VCC1 and VCC2 are reversed.
• The capacitors were removed incorrectly or not removed.
• Short circuit in soldering.
• Data collection requires wireless reading of the key simultaneously; if the key is not positioned correctly, it will not be detected.

Check the above and collect key data again.

Xhorse Toyota XM38 Only Works when Push Start Solution

 Problem:

Trying to make a Smartkey for Toyota Land Cruiser 2018, 433.92mhz FSK. I prepared a Xhorse XM38 XSTO01EN key and I programmed it with IM608 Autel. The remote worked well but the transponder only works if you pushed the start/stop button with it, If I moved the key a few centimetres away from the button, the car would not detect it, and the engine would not start.
The only problem is that for the vehicle to detect the transponder and start the vehicle, you have to stick the key to the start button, as soon as you separate the key a few centimeters, the transponder signal is lost. Why the new Xhorse key only works over the start/stop button and not works if you moved away a few centimeters.

Solution:

Change signal strength had that issue on Hilux.

Change the signal strength.

On the menu of  vvdi mini Key tool, you look at

Toyota smart Key setting, and the signal value would be reduced.

If it still not working, try the following solutions:

Sometimes a smart key generated successfully may not fully function the vehicle: remote doesn’t work, doesn’t have smart feature or even one button fails etc., which needs us to modify smart key’s values manually.

Possible reason:

Xhorse XM smart keys are universal keys, not particular for one model like Toyota Tacoma 2016, so we need to customize XM smart key to find correct values for each car.

Path: Special Function>>XM smart key customization

1. Modify Frequency

Sometimes the frequency options given to us is slightly different from that of the smart key to be programmed.

So read out the frequency “A” that your vehicle wants by Xhorse devices, then read original XM smart key frequency “B” and set “B” to “A”.

2) Modify Baud

Read key’s Baud, increase it by 400, and test if it works perfectly.

If not, add Baud again by 400 until it works well. (The last two numbers may vary automatically, which is normal.)
