Read and Write Audi Air Suspension Control Unit by Xhorse VVDI Prog

 Here is the Audi Air Suspension Control Unit.

It has 2 micro chips.

The first microcontroller.

The second microcontroller.

In general, there was a problem that at a speed of over 120 km/h, the air suspension dropped into an error for all 4 level sensors, when dropping below 120 km/h, all errors disappeared. It was decided to reflash the unit. It contains 2 Motorola microcontrollers. Xhorse VVDI Prog programmer can flash and read them.

General appearance

Connect module with vvdi prog.

Read and write Motorola MC912D60 secured chip.

Updated!
The firmware flash helped! There are no errors when increasing the speed. I was driving at 160 km/h and the car dropped to the first position.

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 Prog and VVDI2 2010 Ford Transit All Keys Lost

 2010 Ford Transit Mk7 all keys lost and active Cat1 factory alarm.

Key learning cannot be carried out by normal OBD operation with alarm active as key learning by OBD is blocked.

Removed BCM, read key data (chip MC9S12DG256) directly from the module using xhorse vvdi prog on the bench, added a new key on the bench with xhorse vvdi2, installed BCM back to the van, switch ignition on with registered key and alarm is deactivated.
Now we can erase all keys and add new all by OBD.
