How to Secure VVDI Super Chip in Xhorse Remote?

 There are many methods to secure xhorse vvdi super chip in universal remotes.

1).

Using adhesive lined heat shrink. For example, this particular car was a 18 camary all keys lost. oem flip key. The user cloned super chip from a new H key. Generated remote. Use IM608 to learn key then remote. All working good.

2).

Super glue works just fine too.  But sometimes will stuck cap etc messy and many times have to open a new tube for every Job. Gets annoying and messy.

I use hot glue, and position it into the tip of the flip key. Some of the remotes have a small LED you might be covering.

3). some use silicone

4).

I use glue stick for glue guns but just use my lighter to melt the glue. No need a glue gun or wait time to warm up etc. takes literally 10secs to drop some glue on it and done.

5).

just buy super remotes they have built in super chip.

NOTE: XHorse makes several versions of Toyota look alike keys, but they don’t have chips. It’s not like the Ford style where you get to choose with or without chip.

How to Fix VVDI2 Cannot Read Kline VW Polo Golf4

 Here comes the DIY solution to xhorse vvdi2 unable to read VW K-line dash problem.

Unable to read k-line polo, golf4 VDO dash but able to read Sharan k-line edc15 ECU but unable to learn keys to the very same car (can’t connect to immobox or similar error).  Took apart but there is no burnings.

It was id44. Separated immobox behind the odo with edc15. Pin from ecu, precode 7935 to VAG id44 and learn thru channel 25.

DIY Solution:

The vvdi2 is working again. Here is the solution

After disassembled the vvdi you MUST be extremely careful with the big yellow backup battery pins!! If you connect them the DALLAS (security chip) will be deleted immediately and you have to send back to china to reprogramming. There is no other way to repair!!! YOU HAVE BEEN WARNED!!!

1: Remove the cable from the vvdi and check the connection with multimeter. This two pins on the first picture must be connected

2: Disassembly the vvdi2 vag and attach the cable to the vvdi and check with multimeter the connection between the obd plug pin #7 and the marked pin on the pic

3: There is a MOSFET relay which is switching the port. Check for burning marks Here is the datasheet

4: On the third picture there is a multiplexer. Because only one kline driver working in the vvdi2 if any other pin using the kline somehow able to switch to pins. This multiplexer doing this. Here is the datasheet Mosfet pin #4 connected to ADC1606 pin #22

5: UART to Kline bus driver. This device is “translate” between the car kline network and the vvdi2 MCU. Here is the datasheet ADC1606 pin #28 connected to KLine driver pin #6

You can’t really test the switching components. The only sure way when you replace them. You can replace the mosfet from any other neighboring one, but the multiplexer isn’t available for me thus i skipped that part. Instead of i replaced the Kline bus driver, after the change my vvdi is able to communicate on kline again.
Hope it helps.

Xhorse Condor II Breaks Cutter 1.5mm when Calibration?

Problem:

I have a problem with my xhorse condor mini plus 2! I am new at this work. I have broken 4 milling cutter (1.5mm) the latest I broke is yesterday when i make a update and I want to recalibrate  I use 1.5 mm cutter for calibration. when I start the machine I put hon66 calibration key but not a blank key I have used this key before for calibration and It broke 1.5 milling cutter.

Solution:

You set the blade speed to the highest speed. Don’t put max speed. The rule is to slow down.

Use cutter 2.5mm to cut any type of key without changing. You will not find any problems at work.

If not working, put di-electric compound on the tip of your probe and cutter. After that do an electric conductivity test before calibrating under the device information tab at the bottom of your Keytool Max or Xhorse App. It sounds like you’re probe and/or cutter is not getting proper electrical conductance.
