How to Resolve 'Try Frequency Failed' Error with Xhorse VVDI Prog and MQB Adapters

Hey there, welcome back to our channel! Today, we're tackling a common issue faced by users of the Xhorse VVDI Prog and MQB Adapters: the dreaded "try frequency failed" error. Have you ever found yourself stuck in this frustrating situation? Well, stick around because we've got the solution you've been searching for!
Now, let's delve into the problem. Some users have reported smooth operations when using the VVDI Prog with the soldering method to read multiple dashboards. However, when it comes to the MQB48 solder-free adapters, things tend to hit a snag with the try frequency failed error.
But fret not, because we're here to guide you through the solution step by step. First off, if you're encountering only the frequency failed error, it's crucial to check the FLMD0 voltage. Here's how:
Step 1: Disconnect the MQB adapter from the cluster.
Step 2: Connect only the MQB adapter to the VVDI Prog, ensuring both are powered with 12V.
Step 3: Proceed to read by TEST_OPTION_15.
Step 4: Measure the FLMD0 voltage. Typically, it should hover around 3.3V.
If you discover that the FLMD0 voltage is lower than expected, fear not! We've got a solution for that too. You'll need to supply 3.3V to FMLDO on the MQB adapter. Check out the image attached below for a visual guide, courtesy of the DK Veteran solution. Rest assured, this method has been thoroughly tested, guaranteeing seamless reads and writes without a hitch!
Now, if you've diligently followed these steps and still find yourself grappling with issues, it's possible that your VVDI Prog is faulty. In such a scenario, it's best to send it back for repair. Once it's been serviced and restored to its optimal condition, you'll be back on track in no time.

YO TENGO EL MISMO PROBLEMA PERO CON OTRO ADAPTADOR ES EL XDNP80 ME DICE QUE NO ENCUENTRA LA FRECUENCIA

[@elilevi19811111]

look when u are saying at step2 " connect only the vvdi adapter " , and u show that it is connected to the cluster ...
